PREFACE

The last report on the status of the National Standard Reference Data

System appeared nearly two years ago. Since that time a number of new data

projects have been started, and the management structure of the Office of

Standard Reference Data has been substantially changed in order to focus more strongly on the use of reference data in the attack on important

national problems. The progress of the system, the plans for the future, and

the relationship of the National Standard Reference Data System to other

organizations are summarized in this Status Report.

The National Standard Reference Data System is intended to provide a basic service to the entire scientific and technical community of the United

States. The success of the program depends very critically on feedback from

the users of the output. We welcome all comments, suggestions, and

criticisms on the program.

CRITICAL EVALUATION OF DATA IN THE PHYSICAL SCIENCES

A STATUS REPORT ON THE NATIONAL STANDARD REFERENCE DATA SYSTEM

January 1977

I. GENERAL SURVEY

A. Origin of the National Standard Reference Data System

The formal existence of the National Standard Reference Data System

dates from 1963, when the Federal Council for Science and Technology asked

the National Bureau of Standards to assume primary responsibility in the

Federal Government for promoting and coordinating the critical evaluation of

numerical data in the physical sciences. The text of the Federal Policy

statement is given in Appendix IA. The program was conceived as a decentralized national effort, with financial support coming from a variety

of Government and private sources, but with NBS responsible for the overall

planning and coordination. The existing data compilation activities

supported by NBS and other Government agencies were to be strengthened, new projects started in neglected technical areas, and the entire effort molded

into a coherent program.

The technical scope of the program gives primary emphasis to welldefined physical and chemical properties of substances and systems which are well characterized. Also included are materials of commerce (alloys,

ceramics, etc.) whose composition may vary only within clearly stated

ranges. Materials of uncertain or widely variable composition are not

included. Properties which depend upon arbitrarily defined characteristics

of the measurement technique are generally excluded. While these definitions

leave many borderline cases, the overall intent is to concentrate the effort

on intrinsic properties that are clearly defined in terms of accepted

physical theory and substances whose composition is so well known as to

justify evaluation of the data. Biological properties and data relating to

large natural systems (e.g., the atmosphere, the oceans) also fall outside

the program.

The major aim of the program is to provide critically evaluated

numerical data to the scientific and technical community in a convenient and

accessible form. Certain secondary outputs, such as annotated

bibliographies and procedures for computerized handling of data, are also

made available. A second aim is to provide feedback into experimental

programs to help raise the general standards of measurement. That is, by

communicating the experience gained in evaluating the world output of data

in the physical sciences, NSRDS helps to advance the level of experimental

techniques and improve the reliability of physical measurements.
B. Organization of NSRDS

When the National Bureau of Standards accepted the primary

responsibility for the National Standard Reference Data System, the Office

of Standard Reference Data (OSRD) was established at NBS to manage the

program. This office is now located under the Associate Director for

Information Programs. The OSRD performs several functions. It has the

responsibility for allocating that part of the NBS budget which is spent on critical data evaluation, both within the NBS technical divisions and

through contracts with outside groups. The staff of the office act as monitors for all projects which are supported. The management of the

publications program of NSRDS is also in the hands of OSRD, and an information service is operated on a limited scale. In addition, OSRD

maintains close contact with other data compilation activities, both in the

United States and abroad. It attempts, both domestically and

internationally, to avoid needless duplication and to improve coverage of

all important technical areas. Finally, a small group within OSRD is

engaged in research and development on computer handling of data and in

application of automated procedures to the activities of data centers.

The actual compilation and evaluation of data takes place in many widely

separated groups. It is these groups which form the components of the

National Standard Reference Data System. The fact that these groups vary

greatly in size, organizational structure, and source of financial support

leads to a certain degree of diffuseness in the system. However, it is

instructive to recognize two broad types of components in NSRDS. The first

is the continuing data center, which has a charter (formal or informal) to cover a certain technical area on a continuing basis. Ideally, such centers

have an assurance of stable long-term financial support. The task of a data

center is to search the world literature on a regular basis, to retrieve and

index papers within its scope of interest, to extract the numerical data,

and to carry out critical evaluation leading to publication of tables or reviews. Many of the centers are highly mechanized and have large,

computer-based files from which bibliographic citations and data can be

retrieved. Generally, they are able to respond to requests for specific

information from the scientific public.

The other type of component is the individual scientist (or small group

of collaborators) who produces a "one-shot" compilation or critical review

as a part of what he regards as his normal scientific activity. Many

valuable data compilations have been produced in this way. Such individuals

do not consider themselves part of a formal data center, and there is

generally no commitment for continuity or updating. The rapid growth of the

scientific literature makes it increasingly difficult for an individual to

do this type of compilation. However, the continuing data centers can serve

a useful function by providing bibliographic back-up for individual

scientists in other locations who wish to write critical reviews or do

critical compilations of limited scope.

In the pattern which has emerged, it is clear that both types of

components are essential for the successful operation of the National

Standard Reference Data System. The concentration of the bibliographic

phase in a relatively small number of continuing data centers offers many

advantages. While these centers carry out some of the critical evaluation

of the data, they generally do not have the expertise on their own staff to cover every aspect of the field in question. By enlisting the help of

specialists in other institutions for evaluations and critical reviews, the

data centers can greatly increase the utilization of their resources.
One of the primary goals of the Office of Standard Reference Data is to

establish continuing data centers in all technical areas which fall within

the scope of the program. In addition, the office attempts to provide funds

for individual compilations and critical reviews of well defined scope and

duration. Since the resources of OSRD are limited, every effort is made to

persuade other agencies and private organizations to participate in the

support of these activities.

C. Organizational Structure of the Office of Standard Reference Data

For management purposes, the Office of Standard Reference Data

originally divided the total scope of its technical program into seven areas

on the basis of their discipline-related content. Those seven areas were:

Thermodynamics and Transport Properties, Atomic and Molecular Data, Chemical

Kinetics, Solid State Data, Nuclear Data, Colloid and Surface Properties,

and Mechanical Properties.

Early in 1976, OSRD restructured its program along application lines

rather than in accordance with scientific disciplines. Organizationally,

the OSRD now consists of an overall management unit, four applicationsrelated data programs, an information service activity, and a data systems

design group. The four data programs are designated Energy and

Environmental Data, Industrial Process Data, Materials Utilization Data, and

Physical Science Data. Briefly, the programs have the following content:

Energy and Environmental Data - Projects dealing with data that have an important application in some aspect of energy R&D or environmental

quality improvement. Projects in chemical kinetics, nuclear properties,

spectroscopic data, and interaction of radiation with matter are currently incorporated in this program. The output of these projects is

particularly important in R&D on new energy sources, environmental

monitoring techniques, and prediction of the effects of pollutants

introduced into air, water, or land.

Industrial Process Data - Projects dealing with thermodynamic,

transport, colloid and surface, and physical properties of industrially

important substances are included in this program. Such data have

particular application to design of new processes in the chemical and

metallurgical industries, optimization of currently used processes, and

general productivity enhancement.

Materials Utilization Data - Properties required for material selection

and R&D on new materials. The structural, optical, electric, magnetic,

and mechanical properties of solid materials are included.

Physical Sciences Data - Projects which involve basic data of very broad

applicability, or which are associated with an important frontier field

of science, are included in this program. Examples are fundamental

physical constants, data on fundamental particles, and data relevant to

radioastronomy

While the new organizational structure involves a substantial change in

management emphasis, the basic disciplinary framework of NSRDS will be

retained. The scientific expertise required for critical evaluation of data

in a particular discipline can best be obtained through a data center

focussed on that discipline. However, the priorities within a data center

will be strongly influenced by the identified needs for data in the

appropriate application areas; thus, the scheduling of tasks within the
disciplinary scope of each data center will reflect the priorities

established for the application areas in the new OSRD organizational

structure. In addition, more emphasis is being given by OSRD to the

packaging of data in formats appropriate to the various areas of

appl ication.

Obviously, the technical output of many of the data centers is

applicable to more than one (frequently to all four) of the program areas.

The OSRD program managers maintain close communication with one another to assure that the full resources of the system are available as needed without

any constraint which might arise from arbitrary dividing lines.

What the new organizational structure offers is a better, more readily

identified match between the needs of outside users and the capabilities of

NSRDS to supply reliable data relevant to major national problems. Taking

full advantage of this match requires close interaction with data users,

with Federal agency representatives who are working to solve these national

problems, and with data programs in other countries. Such interaction is

discussed in Section II of this Report.

D. Information Resources in OSRD

1. OSRD Library . The Office of Standard Reference Data has built a broad, although selective, collection of reference data compilations and

ancillary publications within the scope of the NSRDS. A list of the

holdings was published in September 1970 as NBS Technical Note 554,

Annotated Accession List of Data Compilations of the NBS Office of Standard

Reference Data . NBS TecHnical Note 554 listedabout 1300 documents^ The

collection has continued to grow. As of September 1976, the OSRD Library

housed about 3000 publications—one of the most extensive holdings of this

scope in the world. This is not a lending library, but the use of the

documents by visitors within the library is encouraged. In the summer of

1976, the OSRD Library was relocated physically as part of the main NBS

Library. The data collection occupies its own separate set of shelves but

is also treated as an integral part of the Library's reference material.

2. Inquiry Services . The Office of Standard Reference Data attempts

to answer, within restrictions imposed by limited staff and time, inquiries

concerning data in the physical sciences and engineering. Information and

data are provided from NSRDS publications and other available sources. Inquiries may be referred to data centers and individual specialists in NBS

and elsewhere. At times references are provided; if available and

appropriate, copies of publications or excerpts therefrom containing the

requested data are furnished. OSRD normally receives about 1000 requests

and inquiries per year. Under the system-wide cost-recovery policy, custom

services which require a substantial amount of time are billed to the

requestor

E. Data Systems Design Activities

The Data Systems Design Group devises computer techniques to enable the

NSRDS data centers to automate their work in such a way as to reduce

clerical costs, speed up publication, reduce errors, and reduce the cost of

typesetting their output. Activities of the group are focussed on the

design, implementation, and application of a number of general-purpose

computer programs for storage and retrieval; file manipulation; and
computer-assisted text preparation, editing, and printing. In the latter

area, the group is working in close collaboration with the Computer-Assisted

Section of the NBS Office of Technical Publications in developing and

applying a variety of computer-based systems for more effective use of the

Electronic Composing System at the Government Printing Office.

Current Activities of the Data Systems Design Group include:

1Design , Implementation , and Appl ication of the NBS Typographic System

The text handling system based on the General Purpose Scientific

Document Code (GPSDC) is used as the common data code of the NBS Typographic

System. Interface programs have been written that permit information

keyboarded on three different computerized text-editing systems to be

converted to GPSDC. Another program is used to convert a GPSDC file into a Linotron driver tape used to typeset material on the Linotron 1010

Phototypesetter at the Government Printing Office (GPO) . This. allows the use of a Model 37 teletype or equivalent ASCII coded terminal with an online text-editing system to prepare material to drive the Linotron at GPO

directly using the NBS Typographic System. For those without access to one

of the accepted on-line text editors, provision is made for input from

cards, paper tape, or ASCII coded magnetic tape.

The three on-line text editors that interface are: the ATS system that

runs on IBM 360 or 370 computers; the EDTEXT system that runs on UNIVAC

1108' s ; and the RUNOFF system that runs on Honeywell and some Digital

Equipment computers.

For cases where character size and page characteristics vary within a document, a set of commands keyboarded in red has been implemented. These

special commands along with the formatting commands required by the on-line

text-editing system are used by the NBS Typographic System to control the

format of the phototypeset page.

Because editing of data and text files in the GPSDC system is

cumbersome, a program was written and implemented to convert GPSDC files

into ATS Archival form. In this form corrections and formatting or typesetting commands can be entered easily from a keyboard. This technique

is now standard procedure for publications keyboarded in GPSDC format.

2

Automatic Typesetting and Composition of Data Tables

A major fraction of the effort in this area involves production of NSRDS

publications from existing card files and computer tapes. The program

SETLST with multiple table substitution has proved to be most versatile for

handling fixed field information on data tapes. It is used to rearrange the

data as desired and to insert typesetting codes required for input to the

typography programs at the Government Printing Office. It is also used to

convert data to the required form for input to the NBS Typographic System.

3 • Source Automation of Technical Manuscripts

During the calendar years 1975 and 1976 over 20% of the pages published

in the Journal of Physical and Chemical Reference Data were prepared for

publication using automated procedures which feed more or less directly into

computerized phototypesetting machines. During this same period 50% of all

the publications of the Office of Standard Reference Data that were printed

via the Government Printing Office were fully or partially automated.
4 . Data Analysis and Retrieval System

The data analysis and retrieval system OMNIDATA (previously called

TODARS) has been modified to improve its efficiency, and more modules have

been added to enhance its capabilities. The general-purpose system has been

used productively both interactively and in the batch mode to operate on a number of NSRDS files (including unusual data bases), NBS files, and files

of users at other agencies. Examples of production uses include the

correcting and updating of the crystal data files in preparation of NBS

Magnetic Tape 9, the publication of the crystal data space-group tables, and

the production of various types of indexes associated with JPCRD. It is

presently operative not only at NBS, but on the 1108 computer at the

Department of Housing and Urban Development. The final documentation for

OMNIDATA is in process, a training course has been given, and several

workshops and further training sessions have been planned.

Recent Data Systems Design Accompl ishments

Productive uses of the OMNIDATA System include:

a. A portion of OMNIDATA in absolute form and expressly tailored to run

on the computerized version of the crystal data files was demonstrated online as an adjunct to the following talks:

"The NBS Crystal Data File: On-Line and Off," Mighell, Ondik, and

Breen, presented at the Tenth International Crystallogr aphic Congress,

Amsterdam, The Netherlands, August 1975.

"Crystal Data: On-Line Computer Search Capabilities," Mighell, Ondik,

and Breen, presented at the American Crystallogr aphic Association Winter

Meeting, Clemson, South Carolina, January 1976.

b. The system was used extensively to analyze and update the crystal

data files, in order to prepare them for sale as NBS Magnetic Tape 9.

c. The publication, "Crystal Data Space-Group Tables," Mighell, Ondik,

and Molino (Breen) , appears in Volume 6 of the JPCRD. Without the aid of

many of the OMNIDATA modules, this publication would have been delayed a minimum of two years.

d. The module KWOC (Keyword Out of Context) is a powerful tool for

indexing and has been used productively to prepare various indexes for the

JPCRD. Included are an index of words in the title and one for keywords and

properties. The module has the facility of putting in special flags,

recognizing certain characters (_i.e. , a shift symbol) , and outputting a file

which can then be sent forward for typesetting.

e. OMNIDATA has also proved useful for handling other types of data

bases, both at NBS and in other agencies, such as the Department of Housing

and Urban Development. NSRDS Data Files Available for Distribution on Magnetic Tape

The Office of Standard Reference Data has made three additional magnetic

tapes available for sale by the National Technical Information Service.

They are:

NBS Magnetic Tape 8, EPA/NIH Mass Spectral Data Base 1975 Edition , contains

about 11,300 mass spectra which were acquired by EPA and NIH for the Mass

Spectral Search System.
NBS Magnetic Tape 9, Crystal Data Tape , Derived from the 3rd Edition o£

Crystal Dat a Determinative Tables , contains the cell parameters, Z, space

group, measured density, X-ray density, formula, inorganic name, and

determinative ratios for approximately 24,000 crystalline compounds.

NBS Magnetic Tape 10, Atomic Spectral-line Intensities , contains the

intensity, character, wavelength, spectrum, and energy levels of 3900 lines

in the spectra of 70 elements.

F. Standard Reference Data Legislation

The Standard Reference Data Program was established under the general

enabling legislation of the National Bureau of Standards. In addition, in

1968 the Congress provided specific legislative authority for the program

through passage of Public Law 90-396, the Standard Reference Data Act. The

text of the Act is given in Appendix IB.

One of the principal features of PL 90-396 is the provision of authority

for recovering some of the cost of the program through user charges. In

order to make this possible, the Secretary of Commerce is authorized to

copyright publications which result from the program and to assign this

copyright to others. Several contracts have been negotiated under this

authority. In particular, OSRD has contracted with the American Chemical

Society and the American Institute of Physics to publish the quarterly

Journal of Physical and Chemical Reference Data . This Journal has completed

its fiftTT~year of puBTTcation. With the appearance of the last issue of

Volume 5, 88 data compilations have been disseminated to users through this

medium; in addition, two major compilations have appeared as Supplements.

Over 1200 subscriptions to JPCRD are now in force, including foreign

subscriptions in 44 countries.* Subscription to the Journal and sales of

Supplements and individual reprints have provided a useful financial return

to the program.

Other channels for cost recovery have also been established. They

include

1. Sale of reports and magnetic tapes through the National Technical

Information Service (NTIS)

2. A formal system by which Data Centers charge for custom information

and data services.

3. A cooperative undertaking with Plenum Press in the publication of a series of NSRDS-der ived bibliographies on specialized topics.

Australi

Denmark
G. Advisory Mechanism

For good management, the NSRDS program must have reliable feedback from

the scientific and technical community. Such feedback is provided on a formal basis by the NAS-NAE-NRC through the Numerical Data Advisory Board

(NDAB) . The scope of the NDAB includes numerical data of concern to all

parts of science and technology. The NDAB also serves as a focus for

coordination with certain other national information programs (such as the

National Materials Advisory Board) and international programs parallel to

NSRDS. In this latter role, NDAB has responsibility for the US National

Committee for CODATA. International undertakings are described more fully

in the following section of this report.

The NDAB administers advisory panels in several of the program areas of

NSRDS. These panels meet periodically to discuss needs and priorities

within each program area. The membership of the panels is drawn from

industry, universities, and Government; an effort is made to achieve

coverage of the major specialities within each area. The NDAB submits a report to OSRD after each panel meeting, in which the current activity is

appraised and suggestions made for future emphasis.

In addition to the principal advisory panels, ad hoc subpanels are convened at the request of OSRD to discuss problems of a more specific

nature. Subpanels of this type have been organized in fields such as Mossbauer spectroscopy, interatomic distances, electrical properties of

solids, and thermodynamic properties of aqueous electrolyte solutions.

Meetings of such groups have led to the establishment of new compilation

projects or (in some cases) to the recommendation of procedures for

obtaining and reporting experimental data in the particular field. The NDAB

also serves as co-sponsor with OSRD of symposia and conferences on special

topics when a broader level of professional interaction appears appropriate

to a special subject.

In its broader responsibilities, NDAB is concerned with data outside the

physical sciences and with data on less well-defined properties and

substances.
II. RELATIONSHIPS WITH OTHER ORGANIZATIONS

The two specific authorities under which the NSRDS and the OSRD operate,

a 1963 Federal Policy and the Standard Reference Data Act of 1968 (Appendix

IA and IB) , both identify the need for participation by other Federal

agencies, as well as other appropriate non-Government activities. OSRD has

pursued this objective vigorously. Changes made in 1976 to the

organizational structure of OSRD, designed to match NSRDS capabilities and resources more accurately to the data needs inherent in major national

problems, have brought into even sharper focus the importance of effective

relationships between OSRD and others responsible for attacking and solving

such problems.

A significant fraction of the work of OSRD staff is devoted to

establishing, developing, and utilizing relationships with other individuals

and organizations involved in data generation, data compilation and

evaluation, and the application of data for the solution of problems.

While all of the professional staff members share in this

responsibility, a specific focus has been created through the establishment

of a new position - Special Assistant for Technical Liaison - set up in the

fall of 1976. This Assistant will lead the efforts of OSRD to inform users more effectively of the data available through the NSRDS program and will

strengthen efforts for determining what data are most needed.

Analyzed in the broadest practical terms, OSRD relationships can be

considered in three classes — with other Federal agencies, with private

users and suppliers of data, and with foreign national and international

organizations

A. Relationship with Other Federal Agencies

The National Bureau of Standards has been charged with the

administration of NSRDS; OSRD is the organizational unit of NBS set up for

that purpose. As operator of a national system, OSRD welcomes formal or informal collaboration with data evaluation projects in any of the Federal

agencies, but as a practical matter, adherence to the system by a specific

activity must arise out of the explicit wish of the sponsoring agency. A

number of Departments and other Executive agencies have found it appropriate

to join forces with NSRDS in pursuit of common goals. The longest-standing

and most extensive relationships have come about with the Department of

Defense (and its three Service Departments) and with ERDA (also formerly

with AEC) both of which sponsor their own information analysis centers on topics within the scope of NSRDS. Equally meaningful relationships exist

with the Department of Health, Education, and Welfare, the Department of the

Interior, the Department of Transportation, the Environmental Protection

Agency, the National Aeronautic and Space Administration, and the National

Science Foundation.

The kinds of relationships between NSRDS and other agencies vary widely,

but fall into four broad categories:
1

Common planning to meet existing or anticipated data needs . Another agency may identify a present or new need for data, and may

work with OSRD to determine what data are already available, what

current data projects could supply data, what experts might assist,

or how a new data project might be set up. A frequently used device

for common planning is a conference or workshop under joint

sponsorship.

2. Specific advice to agencies from OSRD . Another agency, or one of

its internal information projects, may ask OSRD or NSRDS project

leaders for guidance on data handling, evaluation criteria, use of

computer techniques, etc. OSRD staff members frequently serve on advisory panels for data and information projects supported by

other agencies.

3. Joint support of data work. In many instances, other agencies have

transferred funds to NSRDS data projects to support some fraction

of the work. Frequently, a specific data task is involved, and a specific product is provided. In several cases, OSRD contributes

funds to a data project (usually at an academic location) which is

also supported by another agency.

4. Project management by OSRD . Here another Federal agency contracts

with OSRD to manage a program of substantial extent, involving

several component projects, in order to develop a series of data

compilations relevant to a major aspect of a problem-solving

effort.

Illustrations of these relationships are given below.

OSRD Cohosts Meeting on Transport and Transformation of Pollutants on Land

and in Water

Approximately two hundred scientists met at NBS on May 11-13, 1976, to

discuss physical and chemical processes affecting pollutant behavior in

water and on soil. The Symposium, entitled "Nonbiological Transport and

Transformation of Pollutants on Land and in Water: Processes and Critical

Data Required for Predictive Description," was cosponsored by NBS, EPA,

ERDA, and NSF. It was chaired by L. H. Gevantman (OSRD) and R. G. Zepp

(Environmental Research Laboratory, Athens). The 21 speakers dealt with the

specifics of relating laboratory and field observations and the

incorporation of these results into observational and conceptual models

which could generalize the environmental behavior of pollutants.

It was the consensus that the meeting succeeded in highlighting the

importance of the physical and chemical processes in the environment.

Moreover, while it appeared possible to define and evaluate pollutant

reaction paths in laboratory surroundings, it was far more difficult to

relate these data to observation in the field. More data and more accurate

data were considered vital to further progress in predicting pollutant

behavior

Radiation Chemistry Data Center Advisory Committee Me e t

The Advisory Committee of the Radiation Chemistry Data Center (RCDC) met

on April 30, 1976, at the University of Notre Dame for the purpose of

10
reviewing the past activities and future plans of the data center's

operation. The day-long meeting included a presentation by L. H. Gevantman

of the Office of Standard Reference Data on the new program structure of the

Office and the impact of that program on the data center's activities. The

representative from ERDA was also asked to comment on his agency's view of

the data center. The RCDC is sponsored jointly by the OSRD and ERDA.

The Committee endorsed the data activities of the Center and offered

valuable suggestions for improving the Center's image as a contributor to

the broad field of physical science rather than its narrowly defined area of

radiation chemistry. The Center was asked to increase its efforts toward

improved communication with scientists outside the radiation chemistry area.

OSRD Coordinator in Compiling Energy Storage Data

The Lawrence Livermore Laboratory (LLL) has reached a contractual

arrangement with the OSRD in which the Office acts for LLL in compiling and

evaluating physical properties data on materials of importance for use in

energy storage systems. Under this arrangement the LLL specifies the

materials and properties for which data are required. These requirements

are presented to OSRD, which arranges for the work to be carried out through

its system of data centers or other centers of expertise as required. The

final products, prepared with the guidance and oversight of the OSRD, are to

be submitted to LLL for incorporation into an automated data storage and

retrieval file residing at the Livermore Laboratory. The automated file,

which is under the direction of Viktor Hampel and his associate, Terrence

Quick, will be made accessible to ERDA contractors and others requiring the

stored data. Where appropriate, the OSRD will also publish the data through

its established outlet, namely the Journal of Physical and Chemical

Reference Data and the NSRDS-NBS series.

A pilot study to test the efficacy of the arrangement has been

initiated. It deals with selected properties data of molten salts,

individually and as mixtures, which have potential use in storage batteries.

The Molten Salts Data Center at Rensselaer Polytechnic Institute has been

designated as a source of expertise for the effort. Funding of the effort

has been accomplished by a transfer of funds from LLL to the OSRD.

B. Relationships with Private Users and Suppliers of Data

The ultimate value of reliable reference data lies in their application

by users to the solution of real problems, ranging from the planning and

interpretation of basic research to the design of engineering components, or the identification of a trace contaminant in water or air. OSRD regards its

relationships to its users as the key factor in program management. These

relationships call for good communication in both directions, a continuing

educational program, and constant exploration by OSRD of additional channels

for reaching and satisfying its customers. OSRD also recognizes its

responsibility to work with private suppliers of data, to cooperate with

them in avoiding duplication of effort, to supply data to them when

appropriate, and to utilize fully their capabilities for disseminating data

to specialized or general user groups.

A systematic effort to imptove technical liaison with users is already

in effect, as evidenced by the presence of a new staff position within OSRD.

Other members of the OSRD technical staff continue as always to consult with

users, to plan and manage cooperative data projects, and to associate their

activities with those of private data suppliers.

11
Four categories of liaison and relationships are at present most

important:

1. Cooperative data projects with private industr ial users . The 1975

Status Report described the establishment of a project (with sponsorship by

several industrial corporations) to develop a definitive set of

thermophysical and related thermodynamic properties of ethylene. That

project continues and has shown good progress. Further details are given in

the relevant project description under "Industrial Process Data", Section

IV. C. below. A second, and potentially much more far-reaching cooperative

project is now in the early stages of exploration. It concerns the

feasibility of a joint industry—government data base for use in chemical

engineering process design calculations. The nucleus of the data base would

consist of continuously upgraded data on the thermophysical and

thermodynamic properties of 500 to 1000 ubiquitous chemicals which all

industrial chemical manufacturers must deal with from time to time. While

this new project is only in the early discussion stages, with no commitments

of any kind, it indicates clearly the continuing role of OSRD as a partner

of industrial data users.

2. Wor k with professional societies . OSRD has found repeatedly that it can obtain valuable leverage and increase the effectiveness of its

communication with data users by working with professional and technical

societies in cooperative planning and joint data projects. An example is

the recent formation of an ad hoc panel on data for pollutant-soil

reactions, convened at the annual meeting of the Clay Mineral Society in

Corvallis, Oregon. The panel met on August 1, 1976. L. H. Gevantman of the

Office of Standard Reference Data led the meeting. Representatives of the

Environmental Research Laboratory, Athens, were also present.

Each of the participants reviewed briefly some of the aspects of the

state of knowledge concerning pollutant-soil interactions. These

presentations were followed by a discussion period which focussed on which

data were suitable for compilation and evaluation. The consensus was that,

despite the variety of reactions observed between soil and pollutants, a matrix of about 25 soil systems and a small selected group of typical

organic and inorganic pollutants defined the area of primary interest, and

that a critical review of the data relevant to these contributions would

make a valuable contribution to the literature.

3. Work with specialized data groups . The establishment of dataoriented committees, panels, etc., for specialized scientific topics, is

becoming a frequent occurrence. OSRD encourages such groups, sometimes

sharing responsibility for bringing them into existence. The programs and

outputs of these groups depend on the need in the field of concern. One common focus is on the quality of data being generated and reported in the

primary literature. For example, a set of "Recommendations for the

Presentation of Raman Spectral Data" has been formulated with approval of

leading professional societies and with input from practitioners of Raman

spectroscopy in the United States and Canada. The recommendations evolved

out of discussions which began under the sponsorship of the Numerical Data

Advisory Board of the National Academy of Sciences with the informal

cosponsorship of the Joint Committee on Atomic and Molecular Physical Data

(JCAMP) A. Lee Smith, of Dow Corning Corporation and. Chairman of JCAMP,

chaired the first session.

12
Gregory Rosasco, of the NBS Inorganic Materials Division, spearheaded

the subsequent 6-month effort in which the recommendations were drafted,

reviewed, and put into final form with the cooperation of JCAMP

(representing 10 professional and technical societies) and the ASTM Special

Committee on Molecular Spectroscopy. An appropriate channel for publication

of the recommendations is now being considered. A similar set of

recommendations for Mass Spectral Data is also being developed.

This particular phase of the NSRDS program goes back to the 1966

"Specifications for Evaluation of Infrared Spectral Data," prepared by the

Coblentz Society Board of Managers, which has had substantial impact on the

several reference catalogs of IR spectral data published throughout the

world. Both the Raman and IR recommendations were prepared by groups of

experts representing U.S. industry, government laboratories, and

universities. NBS leadership in these efforts is recognized by the

participants as a highly valuable catalyst for development of common ground.

4 . Cooperation with publishers of handbooks and other data

distributors . While OSRD tries to make its own publication efforts as effective as possible, there is clear recognition that many data-users have

other channels for access to the data they need. Handbooks rank high among

these channels. Accordingly, OSRD takes every opportunity to see that its

data compilations get further distribution through other publishers and

disseminators. For example, the 56th (1976) edition of the familiar

Handbook of Chemistry and Physics contains 17 tables of data derived

directly from NSRDS compilations. Another example has an international

flavor. A professor at a Japanese university has recently taken a major

initiative in helping to distribute NSRDS-NBS publications in Japan.

Increased Japanese interest in these publications, particularly those

produced with the cooperation of the Radiation Chemistry Data Center (RCDC)

at the University of Notre Dame, has spurred the establishment of a unique

arrangement between the Office of Standard Reference Data (OSRD) and the

Japanese data distributor. Under this arrangement he collects orders for

each document from scientists in Japan, and then sends an order for the

required number to the OSRD. The first exchange, involving the sale of over

200 copies of four reports (NSRDS-NBS 43 and Supplement, NSRDS-NBS 46, and

NSRDS-NBS 51) has been completed. The OSRD hopes that this new arrangement

will lead to increased exposure and sales of its publications in Japan--not

only those in the NSRDS series, but also the Journal of Physical and

Chemical Reference Data .

C. International Cooperation

In the period since the establishment of NSRDS, data evaluation

activities in other parts of the world have increased considerably. Formal

governmental programs similar to NSRDS have been established in several

countries. In the U.K., the Science Research Council administers a program

which includes the support of a number of data centers in the physical

sciences. In the Soviet Union, the Academy of Sciences supports several

data evaluation projects, and the State Service for Standard Reference Data

(GSSSD) has broad responsibility for scientific and technical data. The

Federal Republic of Germany has recently (1975) established an overall

organizational structure for an information system for physics data

(including some physical chemistry aspects) to be operated by the

Zentralstelle fur Atomkernenergie-Dokumentat ion (ZAED). In France, the

Bureau National pour 1 ' Information Scientifique et Technique (BNIST) is

developing a substantial information program with a strong data component.

The Office of Standard Reference Data maintains liaison with these groups

13
with the aim of avoiding duplication in data compilation projects and

promoting maximum compatibility of output. Proposals requesting support of

projects in subject areas of mutual concern are exchanged for comments.

The establishment of the Committee on Data for Science and Technology

(CODATA) in 1966 has provided a continuing formal framework for

international cooperation. CODATA is a committee of the International

Council of Scientific Unions (ICSU) and contains representation from twelve

international unions and, at present, fifteen countries, plus two associated

organizations. The Secretariat is located in Paris. The main purpose of

CODATA is to encourage, on a world wide basis, the production and

distribution of critically evaluated numerical data. One of its first tasks

was to publish an International Compendium of Numerical Data Projects

(Spr inger-Verlag) , New York-Heidelberg-Berlin, 1969). This volume lists

identifiable data compilation projects throughout the world, with

information on their scope, mode of operation, and form of dissemination of

output. A revision is in progress. A major feature of the CODATA program

is a series of biennial conferences, which bring together leading compilers

of data and sponsors of data programs throughout the world. The most recent

of these conferences, held in Boulder, Colorado, in the summer of 1976, is

described in Section III of this Report.

CODATA has established Task Groups in a number of special areas,

including Chemical Kinetics, Presentation of Data in the Primary Literature,

Accessibility and Dissemination of Data, Fundamental Constants, Key Values

for Thermodynamics, Training in Data Handling, Computer Use, Transport

Properties, Data for Industrial Needs, and Internationalization and

Systemat ization of Thermodynamic Tables.

In other areas, CODATA task groups have received endorsement and

sponsorship by Unesco on topics of common interest. The resources of CODATA

are used by Unesco in constructing UNISIST, a developing world scientific

and technical information system. Members of NSRDS data projects and staff

members of OSRD have been active in all of the CODATA task groups.

While CODATA provides a major sponsorship for multinational attention to

data needs, there are other international foci as well. For example, a subcommission of the International Union of Pure and Applied Chemistry

(IUPAC) met recently to discuss the development of a specific data program.

Subcommittee V.6.1. on Solubility Data of the International Union of Pure

and Applied Chemistry (IUPAC) held its 3rd annual meeting at Virginia

Polytechnic Institute (VPI) in Blacksburg, Virginia, on July 9-11, 1976.

The meeting was chaired by A. S. Kertes of the Hebrew University and was attended by 13 other members and observers. L. H. Gevantman of the OSRD was

invited to attend as an interested observer. The business of the

subcommittee centered on the details of issuing a series of publications of

data on the solubility of substances in three main categories, namely:

a. The solubility of Gases in Liquids

b. The solubility of Liquids with Liquids

c. The solubility of Solids in Liquids

Discussions on technical guidelines for compiling and evaluating data,

formats for reporting data, and assignment of responsibility to subcommittee

members for identifying and persuading experts to carry out the actual work

in the assigned areas took up the bulk of the allotted time. A course of

action designed to deliver sufficient material to the publisher (Pergamon)

14
for issuance in 1978 was agreed upon. The next meeting of the Subcommittee

was scheduled to take place in Warsaw, Poland.

OSRD relates to other long-established international data projects as well. The International Association for the Properties of Steam (IAPS) is

the organization that provides the International Skeleton Tables for the

Properties of Steam and the accompanying industrial and scientific

formulations. The Skeleton Tables provide the thermodynamic and transport

properties of steam used in the specification and design of power equipment

the world over. At a 1976 meeting of IAPS, new formulations were proposed

for viscosity and surface tension. These will be circulated for

international ratification in the coming months. Work also proceeded toward

the development of a new formulation for thermal conductivity, a new scientific formulation for the thermodynamic properties, and development of

a data base for the chemical reactions of the minor components in the power

cycle which can lead to expensive failures. NBS was represented at the

meeting by J.M.H. Levelt-Sengers and Lester Haar of the Heat Division and by

Howard J. White, Jr., of the Office of Standard Reference Data. White

serves as the Executive Secretary of the International Association for the

Properties of Steam.

Among the bilateral interactions in which OSRD participates, the most

extensive is that with the USSR. Cooperation with data groups in the Soviet

Union has taken place for a number of years under the auspices of

international organizations such as CODATA and IUPAC. This interaction has

been particularly strong in the area of thermodynamic data, where

representatives from the NSRDS Thermochemical Data Center and the Institute

for High Temperatures of the Soviet Academy of Sciences have worked together

on the establishment of key values of thermodynamic properties. Following

the US-USSR agreement on Cooperation in the Fields of Science and

Technology, signed May 24, 1972, these interactions have been brought under

the jurisdiction of the Joint Commission which supervises the bilateral

exchange program. At the present time, Standard Reference Data is one of

the items in the Cooperative Program in Metrology, and several exchanges of

personnel have taken place. Much of the discussion during these exchanges

is concerned with technical details of cooperative data projects. In

addition, broader problems of data dissemination are considered.

Translation and publication rights questions are a significant element of

this bilateral relationship, and some protocols were drafted in 1976 to

provide definitions for future formal action under the Agreement.

15
III. RECENT ACCOMPLISHMENTS

In the time since the 1975 Status Report appeared, a number of

significant advances have occurred in the National Standard Reference Data

System. They involve major new data evaluation projects, new cooperative

undertakings, added service capabilities, and a variety of planning efforts.

Some of these accomplishments have been described earlier in this report to

illustrate specific aspects of relationships of OSRD with outside

organizations. Others are listed below.

CODATA Holds Fifth Biennial Conference

The Committee on Data for Science and Technology (CODATA) held its Fifth

International Conference in Boulder, Colorado, June 28 through July 1, 1976.

More than 15 countries were represented among the 200-plus attendees, and

the scientific program reflected their breadth of activities.

CODATA, a unit of the International Coucil of Scientific Unions (ICSU)

was established in 1965 as an expression of worldwide concern for data,

their compilation, critical evaluation, storage, and retrieval. Its scope

includes quantitative data on the properties and behavior of matter,

characteristics of biological and geological systems, and other experimental

and observational data. CODATA covers all disciplines represented within

the member Unions of ICSU, i.e_ . , the physical sciences-, astronomy, the

geosciences, and the life sciences, but CODATA 1 s activities concentrate on problems which are common to the various disciplines.

CODATA conferences are held every second year. Previous conferences

have taken place at Arnoldshain, Germany; St. Andrews, Scotland; LeCreusot,

France; and Tsakhcadzor, Armenia, USSR. The Boulder Conference drew

participants from Australia, Austria, Belgium, Canada, Costa Rica, Federal

Republic of Germany, France, German People's Republic, India, Israel, Italy,

Japan, Mexico, Poland, South Africa, United Kingdom, United States of

America, and USSR. The United Nations UNESCO organization was also

represented

The program and conference chairman was David R. Lide, Jr., of the

National Bureau of Standards, Office of Standard Reference Data. Other

members of the program committee were Richard Donovick (USA), C.N.R. Rao

(India) , V. V. Sytchev (USSR) , and G. A. Wilkins (UK) . Attendees were

housed in the Kittredge Residence Halls of the University of Colorado, and

the scientific program was held on the same campus.

The program featured sessions on a wide variety of data problems in

general and specific areas. Especially notable were discussions on Data for

Technology, Data on Flavor and Aroma, Data Needs for Energy and

Environmental Programs, Data in the Astro- and Geo-Sciences, and Biological

Data. Other sessions covered General Problems of Data Evaluation and

Analysis, Data Tagging, Computer Techniques in the Handling and

Dissemination of Data, National and International Data Programs, Problems of

Data Center Operation, Evaluation of Thermochemical Data, and Evaluation of

Data in Solid State Properties.

Both preceding and during the conference, a number of task groups of

CODATA held discussions and open meetings. These task groups are the means

by which CODATA brings international expertise into close focus on specific

data-related scientific problems.

16
National and international programs on data were described to the

conferees, including those of USSR, Federal Republic of Germany, Japan,

Unesco (UNISIST) , European Economic Community (Euronet) , and the World

Federation of Engineering Organizations (WFEO)

Proceedings of the conference will be published by Pergamon Press and are scheduled for appearance early in 1977.

Committee to Study Needs for Reference Data

A one-year study of national needs for evaluated reference data has been

initiated by the Assembly of Mathematical and Physical Sciences of the

National Academy of Sciences-National Research Council. The study, which is

being funded by the National Science Foundation, will assess current

organized data evaluation activities in the United States and attempt to

project future needs for data collections, particularly in support of

national R&D programs in the areas of energy, materials, and the

environment. A particular effort will be made to estimate the benefits from

previous data evaluation activities.

The Steering Committee for the study, which is chaired by Professor

Walter Stockmayer of Dartmouth College, held its first meeting in San

Francisco on September 1 and 2, 1976. The Office of Standard Reference Data

was represented by D. R. Lide. Representatives from ERDA and NSF also took

part in the meeting.

OSRD Helps Revise Periodic Chart

Carrying on a cooperation which dates back over 50 years, the Office of

Standard Reference Data has supplied to the Sargent-Welch Scientific Company

needed data for a complete revision of the familiar "Periodic Chart of the

Atoms." The first stage of the NBS/Sargent-Welch relationship occurred when

Henry Hubbard, first secretary of NBS, designed a modernization of

Mendeleev's periodic table, which was published by the W. M. Welch

Manufacturing Company in 1924. Since then NBS has provided new data for

each revision of the Chart; from 1940 through 1965 William F. Meggers was

the active link, both before and after his retirement in 1958. Starting in

1967, the OSRD has worked with Sargent-Welch (successors to Welch

Manufacturing) to revise and update the numerical information presented on

the wall chart, which is well known to physics and chemistry students as a decoration of lecture halls, classrooms, and laboratories.

The latest revision is a sweeping one. All of the numerical and

graphical data on the "Hubbard" chart have been updated by NSRDS Data

Centers. OSRD has also suggested deletion of some outmoded visualizations

of atomic structure. Sargent-Welch will also use the new data in revising a loose-leaf notebook-size tabular presentation. Both updates will appear

early in 1977.

Accompanying the "Hubbard" chart is a booklet, "Key to the Periodic

Chart of the Atoms." The booklet shares the history of the chart, with

Hubbard as the original author, and revisions by Meggers. A complete

rewriting of the booklet is being made by Martin Paul, retired Executive

Secretary of the National Research Council Division of Chemistry and

Chemical Technology. OSRD is assisting in the rewriting work. A number of

NBS staff members shared in the updating.

17
Water Pollution Data

An ad hoc panel on Water Pollution Data was convened in Washington,

D.C., August 14-15, 1975, under the auspices of the Numerical Data Advisory

Board of the Academy of Sciences. The panel of experts chaired by J. Carrell Morris of Harvard University, consisted of representatives drawn

from universities, government agencies, and national laboratories deeply

concerned with the water pollution field. Their discussion focused on the

evaluated data needs required to help establish a programmed approach to

lowering the level of entry of pollutants into the water environment. The

panel reviewed those pollutants identified by EPA to be of danger to the

environment and listed in order of priority the specific types of numerical

property data which would describe their behavior in aqueous media. They

suggested that these prioritized needs could form the basis for data

evaluation projects sponsored by the OSRD. It urged the issuance of data

compilations for ready accessibility and use by modellers and other workers

in the field.

National Center for Thermodynamic Data of Minerals Established in

Cooperation with OSRD

The U.S. Geological Survey took steps in the Fall of 1976 to establish a National Center for Thermodynamic Data of Minerals in cooperation with the

Office of Standard Reference Data as a component of the National Standard

Reference Data System. The aim of the new Data Center is to acquire and

provide, on a continuing basis, critically evaluated descriptions of the

thermodynamic properties of minerals and other geologic materials over the

ranges in temperature, pressure, and composition which are observed in the

geological environment.

Primary emphasis will be placed upon coverage of numerical data needed

to understand the geological environment and to utilize its resources. Specifically, the Data Center will develop critically evaluated

thermodynamic data for all naturally occurring solid phases or the chemical

end-members, as appropriate, and will cooperate with other Data Centers of

the National Standard Reference Data System on the properties of gases and

aqueous ions.

Both OSRD and USGS recognize the importance of assuring consistency of

the output of the new Center with other thermodynamic tables. For that reason the methods of evaluation, including the auxiliary data on key

substances used in analysis of the data on minerals, will be compatible with

the practices of other centers in the National Standard Reference Data

System

The evaluated results will be disseminated to the scientific and

industrial community through the Journal of Physical and Chemical Reference

Data , the publications of the U.S. Geological Survey, by exchanges within

the National Data Center community, and other outlets as appropriate to

achieve the maximum distribution to interested users. The Data Center will work to achieve thermodynamic consistency between

its tables and related tables from other centers, will cooperate in the

improvement of correlation methods, and will avoid duplication of effort.

Vigorous attempts will be made to systematize the effort so that all groups

can benefit from the sharing of common files and output, and the user can benefit from data referred to common bases.
Planning for Self -Cons is tent Thermochemical Data

A meeting of thermochemists and thermodynamicists interested in the

compilation and evaluation of thermochemical data was held at NBS on January

20, 1975. The purpose of the meeting was to discuss ways in which data

evaluators can cooperate to provide self-consistent tables of such data and

most effectively make the results of their evaluations available to all.

The meeting was sponsored by the Office of Standard Reference Data.

At the present time, self-consistent tables are compiled by small groups

working closely together. This system is slow and the relationship of their

results to other results, obtained independently, is uncertain. With the

help of recently developed computer techniques, it should be possible to

develop a network of compilers and evaluators who feed into a central system

to produce larger, more comprehensive sets of self-consistent data.

The meeting on January 20 was an initial step toward the development of

such a network. The meeting was attended by 15 thermodynamicists including

representatives from Canada and the United Kingdom. Several others who

could not attend sent comments in writing.

Phase Diagram Meeting

The Fourth CALPHAD (CALculation of PHAse Diagrams) Meeting was held at

NBS August 18-22, 1975, under the sponsorship of the Metallurgy and

Materials Science Division of the National Science Foundation and NBS. The

Office of Standard Reference Data and the Alloy Data Center cooperated in

arranging the meeting.

The meeting was a specialists' workshop on computer-based coupling of

thermochemical and phase-diagram data and was attended by over 40 experts

representing 7 countries. Computerized numerical data bases and systems for

calculating thermodynamic data and phase diagrams from the data developed in

France, the U.K., and the U.S.A. were discussed in detail and demonstrated

in operation with the use of appropriate computer terminals and readout

devices. Access to these computer-based data banks and computational

systems is currently available by telephone connection in the U.K. and

Western Europe, especially France and West Germany. A system to make

similar services available in the U.S.A. is being started.

Sodium-Sulfur Battery Research

The Second Molten Salts Data Center Workshop was held on September 4-5,

1975, at Rensselaer Polytechnic Institute to review progress on the SodiumSulfur Battery Program. The workshop was organized by the Molten Salts Data

Center, an NSRDS center directed by G. J. Janz of RPI. The research

discussed at the workshop is partially supported by NSF-RANN and includes

work at Rensselaer and the Ford Motor Company.

The discussions involved electrolyte kinetics, measurement

standardization, electrode and cell material corrosion, and efforts to model

cell behavior so as to understand the basic electrolytic reactions. A

program for testing practical Na-S cells was described by M. Breiter of

General Electric.

The workshop was attended by L. H. Gevantman of the Office of Standard

Reference Data who presented a talk on the operation of the National

Standard Reference Data System (NSRDS) and the management functions of the

Office as they relate to physical properties data evaluation.

19
Engineering Information

A joint meeting of the Industrial Research Institute Task Group on Communication of Scientific and Technical Information and the Engineers

Joint Council Commission on Engineering Information was held at NBS on October 2, 1975. The former group consists of industrial R&D managers and

technical information specialists who are trying to promote more effective

use of scientific and technical information in industry. The EJC group is

concerned with general problems of transfer and use of engineering

information.

NBS activities of interest to the two groups were presented in a halfday session. The programs described included the National Standard

Reference Data System, Federal Information Processing Standards, Standard

Reference Materials, Standards Information Services, and work of the WFEO

Committee on Engineering Information. Considerable interest was shown in

these NBS activities, and a useful interchange took place.

Third R.P.I . Molten Salts Data Center Workshop Conference

H. J. White, Jr., and L. H. Gevantman of the OSRD attended the 3rd

Rensselaer Polytechnic Institute Molten Salts Data Center Workshop

Conference on May 7, 1976. The conference, chaired by G. J. Janz , was held

in Washington, D.C., and dealt with a review of the preliminary results

achieved toward establishing KNC> and NaCl as standard calibrants for

electrical conductance, viscosity, and surface tension measurements.

The Calibration Quality Data and Standards Program is an international

effort, with participation from over eight countries, including France,

England, Norway, Romania, Poland, and the German Democratic Republic. The

scientists presented the results of their individual measurements and

compared them with those of the others present. There followed a general

discussion on what further efforts would be required to achieve the desired

degree of agreement. The meeting was concluded with plans and

recommendations for resolving the minor disparities which remain prior to

adopting KNO and NaCl as molten salt measurement standards.

Panel on Reference Nuclear Data Meets at Brookhaven National Laboratory

Representatives of national societies and organizations dealing with

nuclear data assembled as a panel on October 19, 1976, to consider their

needs for reference nuclear data and how these needs could best be met by

the data centers now serving the nuclear science community. A number of

observers representing the funding agencies, the data centers, and the

publishers of nuclear data attended the meeting, which was convened by

Brookhaven National Laboratory. L. H. Gevantman, as a representative of the

NBS (OSRD) , presented a short description of the National Standard Reference

Data System and its role in promoting the publication of evaluated data in

all scientific disciplines, including nuclear data.

The panel, chaired by James Cline of the Institute of Electrical and

Electronic Engineers, listened to a number of talks describing the work

going on at the various data centers which issue evaluated nuclear data.

The panel then considered whether it should continue as an advisory group

for the issuance of reference nuclear data particular to the needs of their

societies. In a general discussion, the individual panel members studied

the adequacy of current publications in meeting their needs. The panel

concluded that it could serve a useful purpose in providing an interface

between the data centers and national society members by disseminating

information about ongoing data activities, and by acting as a channel for

these societies in requesting from the data centers the issuance of specific

nuclear data publications.

20
IV. ACTIVE DATA EVALUATION PROGRAMS

As mentioned earlier in this Report, OSRD has divided its overall data

program into four problem-related technical areas: Energy and Environmental

Data, Industrial Process Data, Materials Utilization Data, and Physical

Science Data. The following pages provide a description of each of the

areas; in the interest of greater specificity, the Energy Data and

Environmental Data components are discussed separately. The descriptions

indicate scope, general content, and special features of each area. Details

of the individual data projects within each area are given in Appendix II.

ENERGY AND ENVIRONMENTAL DATA

The data activities associated with these two problem areas are closely

interrelated. However, for ease of description they are presented

separately. Consequently, the energy data program will be described first,

followed by the environmental data program. In so doing, general reference

will be made to data projects which, while pursued under other OSRD program

areas, impact on the energy and environmental program area.

A. Energy Data Program

A rather substantial fraction of the NSRDS program has traditionally

involved data projects related either directly or indirectly to energy and

its applications. Past associations with the Atomic Energy Commission, as

the predecessor of the Energy Research and Development Administration

(ERDA) , have led to cooperative activities in a number of selected areas

which include radiation and radio-chemistry, basic nuclear physics, and

thermochemistry. For example, the NSRDS has supported the compilation of

data which are needed for nuclear reactor operation and safety. It has also

been involved with data on the effects of radiation on chemical and

biological systems. With the new ERDA responsibilities the NSRDS data

activities have expanded to cover other aspects of the ERDA charter, such as data on fossil fuel systems, combustion kinetics, magnetohydrodynamics

(MHD) , energy conservation, energy storage, fusion, and material behavior.

The OSRD has extended and strengthened its cooperation with ERDA so as to

continue a useful input to the needs of a national energy program.

Program support in the nuclear data area continues primarily in the

Photonuclear Data Center, where the issuance of evaluated photonuclear data

should be of value in solving problems concerned with nuclear reactor safety

and controlled thermonuclear research (CTR) materials. The updated version

of NSRDS-NBS 29, "Photon Cross Sections, Attenuation Coefficients and Energy

Absorption Coefficients from 10 KeV to 100 Gev , " which will be completed in

1978, will also help improve reactor shielding technology and other

radiation transport applications.

Other projects, such as the 7th edition of the Table of Isotopes, as well as an updated version of Nuclear Spins and Moments, should reach

completion during FY 1977. The close relationships developed with ERDA and

two newly-created nuclear data advisory panels will assure continued useful

effort in these areas.

The energy program has also been expanded with the inclusion of the

activities of the Atomic Energy Levels Data Center and the Transition

Probabilities Data Center, whose data evaluations are used in the solution

21
of CTR problems. Recent publications on the energy levels of all 26

ionization states of iron, and the forthcoming issues on chromium,

manganese, and the rare earths are examples of such useful data products.

Similarly, transition probabilities for many stages of ionization of

vanadium, chromium, manganese, and iron are being compiled and critically

evaluated for publication in FY 1977. A critical compilation of electron

collision cross section data for hydrogen and alkali metal atoms is being

assembled by the Atomic Collision Cross Section Information Center to aid in

modelling of MHD plasmas.

In the area of energy source utilization pertinent thermodynamic and

physical properties data for a coal gasification handbook are being

assembled. This project is described under the Industrial Process program.

A new data center dealing with the thermodynamics of geological materials

has just become affiliated with the NSRDS and should help to provide

reliable data for R&D on geothermal energy. Some data outputs of the

Aqueous Electrolyte Data Center should also be of use in this area. These,

too, are more fully described under the Industrial Process program. The

Chemical Kinetics Information Center has issued a bibliography entitled,

"Chemical Kinetics of the Gas Phase Combustion of Fuels," and a project is now under way aimed at extrapolating kinetic rate data measured at room temperature to high temperatures where combustion reactions take place. Yet

another project is evaluating rate data on reacting of electronically

excited atomic and molecular species.

Finally, a sizable program has been launched in the area of energy

conservation. The Lawrence Livermore Laboratory has requested the OSRD to use its data center resources for gathering evaluated data on materials

designated for use in electrical, mechanical, and chemical storage devices.

These evaluated data are to be entered into an automated data storage and

retrieval file for use by scientists and engineers who are designing energy

systems. To date, contracts have been let with the Molten Salts Data Center

to evaluate selected molten salt systems proposed for use in storage

batteries and fuel cells. The Plastics Technical Evaluation Center is

examining mechanical properties data on composite materials for flywheels.

Data on other energy storage systems, such as chemical storage of hydrogen,

are under consideration.

OSRD program activities relevant to energy data should continue to

expand as new technological breakthroughs occur in fields such as solar and

fossil fuel utilization. Industrial emphasis on gaining increased

efficiencies in energy use will be aided by more reliable data. These, in

turn, must come from a harder evaluative look at the numerical data now

extant in the literature.

B . Environmental Dat a Program

The capability previously established in the NSRDS in areas of gas

kinetics and thermodynamics has permitted the OSRD to move expeditiously

into data projects in aid of environmental research. For example, it was possible to select and apply evaluated thermodynamic data on waste materials

to the design and operation of incinerators. Similarly, evaluated kinetic

rate data on gas phase reactions of simple compounds could be selected and

used to model their behavior as pollutants in the stratosphere. The task of

compiling and evaluating data on pollutant behavior in the water environment

is more difficult because of the size of the effort and the more complicated

behavior of pollutants in water. A start has been made to identify data

needs through close associations with the EPA and the Geological Survey.

22
Efforts by the Chemical Kinetics Information Center to furnish reliable

kinetic rate data on reactions affecting the destruction of the

stratospheric ozone layer continue. A series of evaluated data tables

issued by the Center were used by the NAS-NRC Committee on Atmospheric

Pollution in issuing its report recommending a plan for dealing with the ozone depletion problem. An important data compilation related to this

problem and dealing with the rate constants of CIO reactions will appear in an early issue of the JPCRD. x

Projects to study the reaction kinetics of the combustion of fossil

fuels have been initiated. While aimed primarily at an improvement in

energy technology, such efforts also relate to modelling pollutant behavior

in the atmosphere. Close liaison is maintained with data evaluation

projects, both in the United States and in the United Kingdom, which are concerned with lower atmospheric pollution.

Several data projects dealing with problems related to water pollution

have been established. An NAS ad hoc panel was convened to consider needs

and priorities for water pollution data. A series of recommendations

emerged dealing with both the inorganic and organic trace constituents now

found in water. Specific requirements for the physical properties of many

of the compounds were cited as needed for input to mathematical models used

to describe the origins, reactions, and ultimate fate of these constituents

in the water environment. High on the list of priorities was pollutant

compound solubility. As a consequence, two projects on the solubilities and

solubility products of inorganic materials in water are under way. A third,

dealing with activity coefficients of inorganic compounds, is being pursued

in the Aqueous Electrolyte Data Center. A report containing evaluated

activity coefficient data for the alkaline earth halides is scheduled for

publication in the JPCRD. All of the solubility efforts are being

coordinated with the IUPAC Solubility Data Panel so that duplicative efforts

are avoided.

A symposium on Pollutant Transport and Transforation in the Water and

Soil Environment was sponsored jointly by the OSRD and the EPA Environmental

Research Laboratory. The program was arranged to detail the state of

knowledge concerning the various pollutants and their movement in soil and

water. Included on the agenda were the results of an OSRD-sponsored data

evaluation project which reviewed the hydrolysis rate constants of selected

organic compounds in water under environmental conditions. The report is

scheduled for publication in the JPCRD. A related data compilation produced

by the Radiation Chemistry Data Center deals with the reaction rates of the

hydroxyl radical with organic and inorganic compounds in water. Some

symposium papers describing the use of mathematical models to follow

pollutant behavior in the water and soil environment tended to confirm the

lack of detailed information and data on these substances. It helped focus

the attention of the participants on the need for additional pollutant

physical properties data to improve the ability of models to predict

pollutant behavior. A further lack of knowledge was cited regarding

pollutant-soil interaction, both as soil aggregate and as particulates

suspended in water. Copies of the program and extended abstracts are available from the National Technical Information Service (PB 257347) . As a follow-up to the symposium, an ad hoc panel on Pollutant/Soil Data

Needs was convened to see where useful initiatives could be taken. While

acknowledging that preliminary data activities could be pursued, the panel

recommended a cautious approach to what they viewed as a complex problem.

Discussions with knowledgeable scientists concerning useful data projects in

this area are continuing.

23
The efforts described above have been possible because of existing data

center activity in data projects related to the subject of energy and the

environment. This storehouse of basic physical properties data and the

associated scientific expertise represented in the data centers could be

applied on short notice to newly identified problems. Continuation of such

long-term data evaluation activities is planned to provide the versatility

required for near-term data projects.

INDUSTRIAL PROCESS DATA

As is explained in more detail elsewhere in this report, the management

of the National Standard Reference Data System has been reorganized to

reflect major categories of utilization rather than the disciplinary

categories used previously.

In formulating a program to provide Industrial Process Data, use was

made of the results of an extended series of interviews with individuals in

industrial organizations who are responsible for provision of reference data

within their companies as well as with design engineers. It was clear that

the most-used data are thermodynamic data and data on thermophysical and

transport properties. The thermodynamic data include both the enthalpies

and Gibbs energies of formation which are used to determine the equilibrium

constants of chemical reactions and the PVT properties, enthalpies, and heat

capacities of compounds which are needed to determine their physical

behavior at different temperatures and pressures. The need for data on mixtures was particularly stressed, and the program in this area has been

increased recently. Another area of need, particularly in the metallurgical

field, is the area of phase diagrams. These can logically be considered

thermodynamic data, but are often treated separately for emphasis as is the case here.

Data on enthalpies and Gibbs energies of formation are provided by the

Chemical Thermodynamic Data Center at NBS, Gaithersburg , and by the

Thermodynamics Research Center at Texas A&M University. Data on the PVT and

related thermodynamic properties of fluids are provided by projects in the

Cryogenics Division of NBS, Boulder, and the Heat Division of NBS,

Gaithersburg, as well as at the University of Maryland. Mixture data are provided by the Aqueous Electrolyte Data Center at NBS, Gaithersburg, the

Cryogenic Fluid Mixtures Data Center at NBS, Boulder, and the Thermodynamics

Research Laboratory at Washington University in St. Louis. Transport

properties are covered in the Cryogenics Division, NBS, Boulder, and CINDAS,

Purdue University. For more detailed information on these and other

projects in the Industrial Process Data Program, the reader is referred to

the appendices of this report.

In keeping with increasing emphasis on Industrial Process Data, the

Alloy Data Center has shifted its primary emphasis to phase diagrams of

alloys and intends to become a major data activity in this field. This

reprogramming starts to fill a serious gap in NSRDS coverage which has

existed for several years. The activities of the Alloy Data Center will

reinforce those of the project on Phase Diagrams for Ceramists which is

supported by the American Ceramics Society.

The two groups, together with the Office of Standard Reference Data,

combined to organize a Workshop on Applications of Phase Diagrams in

Metallurgy and Ceramics which was held at NBS, January 10-12, 1977. This

workshop was intended to initiate a more integrated program of data

evaluation and measurement worldwide. It was well attended and

enthusiastically received.

24
A new data center , the National Center for the Thermodynamic Data of

Minerals, has been established as part of the NSRDS by the U.S. Geological

Survey at Reston, Virginia. This center will provide thermodynamic data on minerals for the geochemical community, and these data will also be of

industrial importance for a great many uses in metallurgy and the

preparation and production of inorganic chemicals.

The utilization categories should not be thought of as rigid technical

divisions. It is clear that the data produced by the thermodynamic centers

will be of use in many ways in the solution of problems in other utilization

areas, especially in the energy and pollution control areas. In addition to

the general utility of the data produced, specific data compilations are being prepared by some of the thermodynamic centers in response to specific

energy or pollution-control problems. Among these may be listed the project

to compile thermodynamic data for industrial and municipal incinerator

design in the Chemical Thermodynamic Data Center under the sponsorship of

the ASME, the project to provide a compilation of thermophysical and

thermodynamic properties of chemical compounds derivable from coal which is

being carried out by the Thermodynamic Research Center under the sponsorship

of the Institute of Gas Technology, the compilation of thermodynamic data on selected reactions that might occur in the stratosphere by the Chemical

Thermodynamic Data Center under DOT sponsorship, and the compilation of

thermochemical data on the reactions of selected substances containing heavy

metal ions in aqueous systems being done by the Aqueous Electrolyte Data

Center. The range and variety of these projects illustrate clearly how the

combined resources of the various thermodynamic data centers make it

possible for them to provide specific data compilations for many different,

specific purposes as well as provide the wide-ranging basic data

compilations that are their primary products and are useful for many users

and purposes.

In a similar fashion, data centers in other utilization categories can,

and are expected to, make important contributions to the Industrial Process

Data field. The Chemical Kinetic Information Center, the Molten Salts Data

Center, and the Ion Energetics Data Center can be mentioned in particular.

The last, as the name would suggest, produces thermodynamic data on ionic

species, although the data are not obtained by conventional thermodynamic

methods

The production of data compilations to aid in the solution of specific

problems is discussed above. In addition to designing compilation projects

to serve in the solution of individual problems, it often proves possible to use data compiled and evaluated for other purposes, often as part of the

basic data compilation activities of one or several centers to produce a compilation tailored to the needs of a specific set of users. The data are repackaged to conform with usage in the field in question.

An example of a project of this genre is the project to prepare an LNG

Handbook. This handbook will incorporate data on Liquefied Natural Gas, its

components, and other substances, which have been measured, compiled, and

evaluated for a number of purposes, into a useful engineering handbook.

25
MATERIALS UTILIZATION DATA

In developing a data program relevant to materials utilization

interests, the OSRD has tried to take full advantage of the earlier planning

for Mechanical Properties data, one of the seven categories which composed

the original scope of the National Standard Reference Data System. At the

same time, the program is shaped to a substantial degree by the capabilities

of a number of on-going materials-related data projects which were formerly

included in the Solid State Data portion of the NSRDS. These latter

projects stressed crystallographic data, superconductive materials, certain

aspects of metallurgy, and optical properties of solids relevant to laser

research. The productivity of these existing projects has been well

demonstrated, and a significant level of user expectation exists for NBS to

continue to supply the data they need. Accordingly, the present Materials

Utilization Data program and the plans for its possible expansion contain

elements from both sources.

In 1964 an ad hoc NBS panel drafted a list of mechanical properties

which seemed likely candidates for inclusion in the NSRDS Program.

Financial limitations precluded the initiation of any systematic program in

this area, and further formal planning was postponed for several years. In

1971, one of the OSRD advisory groups recommended (without ignoring

budgetary restrictions) that "the office should give serious consideration

to extending its activities to engineering areas, such as mechanical

properties, electrical properties, environmental studies, and others."

In response, OSRD undertook a new planning effort which started with a review of the 1964 list and involved discussions with a number of materials

research specialists to determine which properties were well enough defined

to warrant consideration. This review yielded tentative lists of properties

for metals, ceramics, glasses, polymers, and liquids (gases were included in

the Thermodynamics and Transport Properties data area) , which were then

circulated to a larger group including users and producers.

The comments and suggestions which resulted were used in the formulation

of a detailed program. Key guidelines included the following:

Output should be useful to all who need and use mechanical

properties data, including scientists, engineers, and designers;

Material of transitory interest should be excluded;

Information being produced by others should not be duplicated;

Base or key values should be emphasized;

A somewhat pragmatic interpretation of the NSRDS guideline, "welldefined properties," should be adopted in regard to mechanical

behavior

Outside of the categories of single crystals and ordinary (low

molecular weight) liquids, the major limitation on reproducibility

of the values of most mechanical properties seems to be our ability

to characterize the materials.

26
OSRD staff concluded that critical reviews would play a large part in

the mechanical properties program. A number of comments suggested including

papers designed primarily to describe the use of relatively new material

properties (like plane strain fracture toughness). It appeared also that

annotated lists of information sources would be useful, since present lists

generally do not identify in a specific fashion the information available

from each source.

As a result of this planning work, OSRD undertook support of three data

initiatives in 1973-5:

a) a series of reviews on elastic constant data for metals and alloys;

b) a book on "Fracture Toughness Testing and Data with Reference to

Meaning and Applications;"

c) a series of critical surveys of data sources, covering selected

materials and properties.

This three-part program was well under way, and already productive when

OSRD restructured its management organization to achieve a better match with

data needs of major national problem areas. One of the four new program

areas was Materials Utilization Data, which as noted above, subsumed all of

the Mechanical Properties efforts, plus several of the projects formerly

within the area of Solid State Data.

Planning for the Materials Utilization Data program did not start from

scratch. At hand were the results of several major outside studies

sponsored by:

a) the National Commission on Materials Policy,

b) the National Academy of Sciences-National Academy of Engineering,

c) the Committee on the Survey of Materials Science and Engineering,

d) the Federation of Materials Societies, the Office of Technology

Assessment, and other bodies.

These and other sources provide ample identification of specific needs

for reliable materials properties data. A major data compilation and

evaluation program can be developed on this basis if funds become available

to support it. Anticipating that only partial funding will be available in

the short term, closer scrutiny is required to set priorities, develop

cooperative projects, define deficiencies in existing outside data programs,

and estimate areas of greatest potential impact. Such a study is in

process, and the results will be incorporated in the future plans for an enlarged program.

The study includes the following elements:

a) Discussion with industrial users and suppliers of materials data;

b) Discussions with managers of present major data projects operated

by professional societies and cooperative industrial groups;

c) Conversations with Deans and Professors of Engineering (especially

mechanical and design engineering) at major universities and

technological institutes;

27
d) Participation with National Science Foundation in pilot studies of

how engineers use data on the job;

e) Convening of several small groups of scientists and engineers in

special materials areas, to focus on details of present and future

data needs —£•£• > high-strength ceramics; synthetic polymers;

composites, etc.

In terms of present status, the Materials Utilization Data program may

be viewed as a rather scattered array of productive projects ranging across

the whole spectrum of already-perceived user needs. The projects on crystallographic data serve the research community well, and are developing

additional outputs to meet applied needs (analytical systems, compound

identification via X-ray diffraction, etc.) as well. The series of four

Critical Surveys of Data Sources has been completed, and users have

expressed approval of the original concept as well as the results. The

projects on diffusion in metals and on elastic constants of metals are concerned with key values of broad interest, where NBS competence can make a unique contribution. The project on fracture mechanics is a prototype

effort —an early attempt to systematize the data aspects of a recentlydeveloped field with broad relevance to both theoretical understanding and

practical applications.

In summary, the present materials data program is a good starting place,

a strong base on which to build.

PHYSICAL SCIENCE DATA

The previously-described portions of the NSRDS program are presented in

terms relating to general or specific applications. While OSRD recognizes

and emphasizes that many of its data outputs are very broadly useful in

application to many different types of problems, it remains appropriate to

place most of the projects in one particular category.

There are some projects, however, whose content is so universal, or so clearly focussed on frontier research, that assignment to a single problemrelated area would be inappropriate. These projects comprise the final

NSRDS program area, which has been given the rather vague title of Physical

Science Data. By intent, the number of projects in this area remains small.

Directly or indirectly, however, the data output of this area has a very

large cumulative impact both on users and on the rest of the data program.

COMMITTEE ON SCIENTIFIC INFORMATION

28 May 1963

Federal Policy on National Standard Reference Data System

There will be established a National Standard Reference Data System

(NSRDS) to provide on a national basis critically evaluated data in the physical

sciences. The NSRDS will consist of a National Standard Reference Data Center (NSRDC) at the National Bureau of Standards and such other Standard Reference Data Centers as may be required.

The National Bureau of Standards will be charged with the administration of the National Standard Reference Data System. This assignment will include the establishment of standards of quality, methodology including machine processing

formats, and such other functions as are required to ensure the compatibility of

all units of the NSRDS.

The National Bureau of Standards will be charged with funding and administering the National Standard Reference Data Center. This Center will be an identifiable part of the National Scientific and Technical Information System (NSTIS).

Standard Reference Data Centers covering certain specific areas of effort may

be established by or be assigned to the various Departments and Agencies in ac- cordance with their specific desires and capabilities. Such Centers will be financed and administered by the Department to which assigned but will meet the quality

standards and other requirements of the NSRDS. Such Centers will be included

as identifiable components of the NSTIS.

The NSRDS may also include Standard Reference Data Centers at universities, research institutes, and other appropriate non-Government activities. To be

included in the NSRDS, such Centers will meet the quality standards and other requirements of the NSRDS and will be included as identifiable components of the NSTIS.

There will be an Advisory Board to review and recommend policy relative to the operation of the NSRDS. It will include among others, representation from

the National Academy of Sciences, National Science Foundation, Federal Agencies

engaged in research and development, and such other representatives of the sci- entific and technical community as the Director of the National Bureau of Standards may determine.

In establishing the NSRDS, the intent is to provide an articulated system of Centers and activities under such coordination and direction as to ensure an out- put meeting quality standards for national reference data in the physical sciences. The establishment of the System should not be construed as preventing the estab- lishment of such Federal or Departmental Data Systems as are required for the

collection of raw or evaluated data to serve engineering or operating needs of the Federal Government or various Federal agencies.

8. Title: PVT and Related Thermodynamic Properties of Ethylene

Location : See below

Project Leade r : H. J. White, Jr., Office of Standard Reference Data,

NBS, Washington, D.C. 20234

Description : This project is supported jointly by industrial

organizations and the government. The goal is a comprehensive, highquality, self-consistent set of densities and related thermodynamic

properties of ethylene. Since the data in the literature do not allow the

preparation of such a set to the level of accuracy desired, the project

involves selected measurements as well.

Measurements of the density as a function of temperature and pressure in

the critical region and below have been carried out by the ERDA Energy

Research Center in Bartlesville , Oklahoma, and in the Heat Division of NBS,

Gaithersburg . These measurements overlap to some extent in the critical

region and have been carried into the supercritical region to overlap with

existing data sets there. The agreement between independent measurements is

excellent and, as a result of these measurements, the behavior of ethylene

in the immediate critical region and in the vapor phase for 50°C below the

critical region is now well established. Measurements are currently being

carried out by the ERDA Energy Research Center on the speed of sound in

ethylene on either side of the two-phase line; by the Cryogenics Division at

NBS, Boulder, on the density of the liquid; and by the Chemical Engineering

Department of the University of Michigan on the heat capacity along the twophase line. These experimental measurements should fill the major gaps in

the experimental data in the literature and permit preparation of a definitive PVT surface over a wide range of temperatures and pressures.

Support for the project has been received from the Government and the

following industrial organizations:

Celanese Chemical Company

Cities Service Oil Company

Continental Oil Company

Gulf Research and Development Company

Mobil Chemical Company

17. Title : Correlation of Thermophysical Property Data of Fluids

Location ; University of Maryland, College Park, Maryland 20742

Project Leadejr: J. V. Sengers

Descr iption : This project is concerned with the evaluation and

correlation of data on the thermodynamic and transport properties of fluids

in the neighborhood of the critical point and with the development of needed

data-correlating techniques applicable in the critical region. These

properties exhibit unique, and, in some cases, large changes as the critical

point is approached and require special correlating techniques to reproduce

the observed behavior and to develop consistent formulations covering more

than one property. It is also necessary that any special techniques used in

the critical region merge satisfactorily with classical formulations known

to apply well away from the critical point.

Emphasis in the project has been put on the thermal conductivity, a property which changes strongly in the neighborhood of the critical point.

A method has been devised for separating the thermal conductivity into a background portion which merges smoothly with the behavior well away from

the critical point and an excess portion.

The methods developed have been applied to water. The density is a necessary factor in separating the two parts of the thermal conductivity and

in developing an expression for the excess portion. The values used were

taken from the set of self-consistent thermodynamic values developed in

another project listed here. An equation expanding the excess portion of

the thermal conductivity around the critical point by scaling-law techniques

has been developed and applied to water with the result that there are now

formulations for the thermodynamic properties and the thermal conductivity

of water in the critical region which are consistent with one another.

Application of the techniques to other fluids is being considered.

Volume 5, No. 3, of the Journal of Physical and Chemical Reference Dat a. This publication comprehends the substance of earlier output from the

center. In the immediate future, the center will develop a mechanized

central data file on superconductive materials, deriving from present

internal holdings plus additional material being collected.

2. Title ; Crystal Data Center

Location ; Inorganic Materials Division, NBS, Washington, D.C. 20234

Project~Leader ; Helen M. Ondik

Description : The Crystal Data Center compiles and evaluates inorganic

crystallographic data from the literature for dissemination to the

scientific and technical community. With the third edition of "Crystal Data

Determinative Tables" in print, the effort is aimed at preparing and

publishing a series of supplements containing data from 1967 to date. Data

for the first supplement are being compiled, and publication is planned for

late 1977. The center has used the existing automated files for the

preparation of "Crystal Data Space-Group Tables," by Alan Mighell of the

center and Bettijoyce Molino of the OSRD Data Systems Design Group. The

Space Group Tables permit the user to find crystals of a specified symmetry,

locate isostructur al molecules, etc.

3* Title ; Cambridge Crystallographic Data Centre

Location : Cambridge University, Cambridge, England

Project Leader ; Olga Kennard

Description ; The Cambridge Data Centre searches, extracts, compiles,

and stores crystal data from the world literature on organic compounds. In

addition, the Centre extracts information from the literature on inorganic

compounds, intermetallics , and minerals which it sends to the Crystal Data

Center at NBS. The data on organic compounds are stored in a computerized

file and include unit cell constants, densities, and space group

designations. These parameters serve as a basis for the identification and

analytical determination of such diverse material as petrochemicals,

insecticides, drugs, biological compounds, and others. This data file in

selected form was automated to produce the Organic Compound volume of the

third edition of "Crystal Data - Determinative Tables," and is being used in

the preparation of the first Organic Supplement which will appear in 1977.

4. Title ; Mossbauer Effect Data Center

Location ; University of North Carolina, Asheville, NC 28804

Project~Leader ; John G. Stevens

Descr iption : The literature involving Mossbauer effect measurements has

grown steadily in recent years; it has application in such diverse areas as solid state physics, analytical chemistry, biophysics, etc. Annual

publication of the Mossbauer Effect Data Index (MEDI) was initiated to

provide workers with a single source of data and bibliographic reference

thereby avoiding duplication of effort spent in searching the literature.

The data include radioactive source, absorber employed, temperature, degree

of shift, quadruple splitting, etc. The MEDI has been published annually

starting with 1970. The 1975 Index was published in 1976 by IFI/Plenum Data

Company

5. Title ; Diffusion in Metals Data Center

Location ; Metallurgy Division, NBS, Washington, D.C. 20234

Project Leader ; J. R. Manning

Description; The project objective is the publication of standard

reference data

-

monogr aphs which provide a review and critically evaluated

data on diffusion in metals and their alloys. Papers from the technical

literature are systematically collected and classified according to the

alloy systems on which they report diffusion data. More than 4000 papers

are examined each year, of which about 2000 are entered into the files of

the center. Monographs for alloy systems important in technology are being

produced, starting with diffusion in copper and copper alloys. The fourth

compilation of evaluated data prepared under this project, "Diffusion in

Copper and Copper Alloys, Part IV, Diffusion in Systems involving Elements

of Group VIII," was published in 1976 in Vol. 5, No. 1 of the Journal of

Physical and Chemical Reference Data . Current efforts of the center focus on additional monographs in the copper series, involving a) N, P, As, Sb,

Bi, and b) 0, S, Se , Te.

6. Title ; Elastic Constant Data for Metals and Alloys

Location ; Cryogenics Division, NBS, Boulder, Colorado 80302

Project Leader: R. P. Reed

Direct Inquiries To: H. Ledbetter

Descr iption ; Elastic properties data for materials that are of

scientific or technological interest because of their relationship to the

interatomic potential in solids and, consequently, to a wide variety of

solid-state phenomena. Technologically, elastic constants are essential

design parameters in any mechanically stressed component-pressure vessels,

ship hulls, rotating machinery, etc.

The first review in this series covered Iron, Nickel, and Iron-Nickel

Alloys (J. Phys. Chem. Ref . Data , 2 (1974) , 531-618) .

A paper on the elastic properties of copper was published (J. Phys . Chem . Ref . Data , 3 (1974, 397-935) . Also a note on the elastic constants of

polycrystals was published ( Phys . Status Solidi , 2, 26 (1974) , K67-70) . A

manuscript on the elastic properties of zinc has been completed and will be

published in 1977.

Reviews on copper-zinc alloys and on aluminum are at present in

preparation.

7. Title ; Optical Properties of Materials

Location : Center for Information and Numerical Data Analysis and

Synthesis (CINDAS) , Purdue University, West Lafayette, Indiana

47907

Project Le ad e: H. H. Li

Descr iption : This project has been established to produce compilations

of critically evaluated refractive index data and related information

pertinent to laser, holographic, and electro-optic systems. The work

includes informal collaboration among NBS , the Research Materials

Information Center (RMIC) at Oak Ridge National Laboratory, and the Center

for Information and Numerical Data Analysis and Synthesis at Purdue

University. A substantial compilation of carefully evaluated data for 20

alkali halides was prepared by H. H. Li of CINDAS and published in 1976 in

Volume 5, No. 2, of the Journal of Physical and Chemical Reference Data . Current efforts under the project include compilation of data for tfie

alkaline earth halides as well as specific coverage of silver halides.

8" Title : Fracture Mechanics Data Handbook

Location : Metallurgy Division, NBS, Washington, D.C. 20234 and

Department of Mechanical Engineering, University of Maryland

Project Leader : R. deWit, National Bureau of Standards, Washington,

D.C. 20234

Description : The objective is to advance the application of fracture

mechanics analysis methodologies to materials engineering and design and to

materials selection processes through the provision of compilations of

reliable data on fracture, a survey of fracture toughness testing

procedures, and a critical review of the applications of advanced materials

properties. To date, four papers (prototype sections of the eventual

handbook) have been prepared on various aspects of fracture mechanics and

dynamic fracture testing.

9. Title : Vibrational Force Field Constants for Polyethylene

Location : Polymers Division, NBS, Washington, D.C. 20234

Project Leader : D. H. Reneker

Description : Review of the previous efforts to describe the force field

of polyethylene revealed inadequacy in the manner in which those force

fields were formulated. Also, a large body of new data, principally in the

low frequency Raman region, has been published since the last comprehensive

review. Molecular vibrational data from the literature and from

measurements made at NBS have been collected and used to obtain the best fit

to theoretical dispersion curves of polyethylene crystals. A draft report

has been completed for presentation of the results in the Journal of

Physical and Chemical Reference Data in 1977.

REVISED! UPDATED!

In 1954, the first edition of CRYSTAL DATA (Determinative Tables

and Systematic Tables) was published as Memoir 60 of the Geological Society of America. In 1960,

the second edition of the Determinative Tables was issued as Monograph

5 of the American Crystallographic

Association, and in 1967, the Systematic Tables were issued as Monograph 6. These editions proved ex- tremely valuable to crystallographers

throughout the world. Recognizing the need for updated crystallographic in- formation, the National Bureau of Stand

ards Office of Standard Reference Data has sponsored the issuance of a new

edition.

This, the THIRD EDITION, should be of particular interest not only to crystallographers but also to chemists, mineralogists, physicists and individuals in related fields of study. The current edition,

which comprises two volumes, Organic and

Inorganic, is a thoroughly revised and up- dated work, containing over 25,000 entries The entries are listed, within each crystal sys- tem, according to increasing values of a determinative number: a/b ratio in trimetric systems, c/a ratio in dimetric systems, and

cubic cell edge a, in the isometric system. In addition, the following information is given: INORGANIC VOLUME $50.00

ORGANIC VOLUME $30.00

axial ratio(s) and interaxial angles

not fixed by symmetry, cell dimensions, space group or diffraction aspect, number of formula units per unit cell, crystal structure, (whether determined), measured

density and x-ray calculated density. Also listed is the name of the compound and synonym(s),

chemical formula, literature ref- erence and transformation

matrix. When available, the crystal structure type, crystal habit,

cleavages, twinning, color, optical

properties, indices of refraction,

optical orientation, melting point

and transition point are also

listed. THIS EDITION culminates years of

effort by J. D. H. Donnay, Johns

Hopkins University, Helen M. Ondik,

National Bureau of Standards, Sten Samson, California Institute of Technology, Quintin Johnson, Lawrence Radiation Laboratory,

Melvin H. Mueller, Argonne National

Laboratory, Gerard M. Wolten, Aero- space Corporation, Mary E. Mrose,
