PREFACE

As a result of the Omnibus Trade and Competitiveness Act, signed into law on August 23, 1988, the National

Bureau of Standards officially became the National Institute of Standards and Technology (NIST). The new

institute retains all of the traditional functions and services of NBS and takes on several new assignments designed to boost American industry in the world marketplace. NIST is working with several new constituencies,

including state and local economic development organizations. Existing NBS programs are continuing under

NIST. Four major new programs are mandated by the legislation: the development of regional centers for

transfer of manufacturing technology; the creation of a focal point within the Federal Government to work

with and support state and local industrial extension services; the creation of an advanced technology program

to support and encourage the rapid commercialization of promising new inventions and technologies; and the

creation of a national clearinghouse of information on state and local technology development initiatives.

The formal existence of the NSRDS 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 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 all the overall planning and coordination. In 1968, Congress

provided a specific legislative mandate for the program through passage of Public Law 90-396, the Standard

Reference Data Act. This Act states the policy of Congress to make reliable reference data available to scientists, engineers, and the general public.

The Standard Reference Data Program has been providing evaluated, high-quality data for a wide range of

applications to industry, government, and academic institutions for over 20 years. Standard reference data have

been utilized to improve design efficiency of various chemical processes, identify potentially toxic substances in

the environment, improve materials durability, and calculate performance of chemical reactors, to name but a few applications. With the onset of the personal computer, standard reference data are even more accessible

and will play an even more critical role in the future.

INTRODUCTION

The NIST Standard Reference Data (SRD) Program provides reliable, well-documented data to scientists and

engineers for use in technical problem-solving, research, and development.

Experts in the physical, chemical, and materials sciences critically evaluate data that result from experimental

measurements, calculations, and theory. The evaluations are carried out through a network of data centers,

projects, and cooperative programs that comprise the National Standard Reference Data System (NSRDS).

Experienced researchers in each area assess the accuracy of the data reported in the literature, prepare compilations, and recommend best values. The outputs are widely distributed as publications and computer-readable

databases.

The formal existence of the SRD Program dates from 1963, when the Federal Coimcil for Science and Technology asked the then-National Bureau of Standards to assume primary responsibility for coordinating the critical evaluation of numerical data in

the physical sciences. In 1968, Congress provided specific legislation for

the program through passage of the

Standard Reference Data Act (PL

90-396).

Current activities in the Standard

Reference Data Program are carried

out in long-term data centers, located

primarily at NIST, and numerous

short-term projects, primarily at university and industrial research centers. In addition, the Program

maintains many long-term collaborations with industry on cooperative

data programs which draw support

from industry and government.
The activities concentrate on the disciplines as follows:

Analytical Chemistry —includes mass spectral data, surface analysis data, and crystallographic data for chemical

identification.

Atomic Physics —includes atomic energy levels, transition probabilities, and collision data used for characterization and modeling.

Chemical Kinetics —includes evaluated data on gas-phase reactions.

Materials Properties — structure and characterization of materials, performance properties, including corrosion

and phase equilibria.

Molecular Structure and Spectroscopy —evaluated data on molecular structures and microwave spectra.

Thermochemistry —includes reliable, widely-used tables of organic and inorganic species.

Thermophysical Properties of Fluids —thtimophysical properties of pure and mixed fluids that are of great itnpor

tance to industry.

Dissemination vehicles are as follows:

National Standard Reference Database Series— Databases on diskettes,

magnetic tapes, and online systems

Journal of Physical and Chemical

Reference Data—A bimonthly journal published jointly with the American Chemical Society and the

American Institute of Physics

ANALYTICAL CHEMISTRY

In the field of analytical chemistry, the SRD Program provides a set of comprehensive, easy-to-use databases

and printed data compilations that help the analytical chemist identify miknown materials, and in many cases, once identified, avoid the need to recharacterize a substance. SRD databases cover a full range of analytical

techniques, including mass spectrometry, surface analysis, and crystallographic structure.

To reach the greatest possible audience, the data collections are offered in several formats: as PC diskettes, on

magnetic tape for inclusion in in-house laboratory systems, as incorporated into instruments themselves, and via

online database systems.

In every case, the data have been fully evaluated, using a variety of techniques. When appropriate, duplicate

measurements have been included for completeness. All the databases are updated on a regular basis. The PC

diskette version of these databases includes an easy-to-use interface that can be mastered quickly and without

having to resort to large manuals.

7
The database can be utilized as a practical analytical tool for compound characterization and identification be- cause the reduced cell (i.e., the lattice) is unique for most compoimds. The database can also be utilized to

prevent redeterminations of published structures. In addition, it is useful in conjunction with other data for

materials characterization.

The file includes reliable data across

the entire spectrimi of the solid state including inorganics, organics, minerals, intermetallics, metals, alloys,

drugs, antibiotics, and pesticides.

ATOMIC PHYSICS

The Standard Reference Data Program has worked together with the world-famous NIST Atomic Physics Program to produce the most comprehensive set of reliable atomic data available anywhere. The NIST collection

of atomic energy levels, transition probabilities, and collision data is widely used by groups for characterizing

and modeling all types of atomic systems, including plasmas, planetary atmospheres, and astrophysical media,

and for health physics applications. Databases and publications make these data easy to find and use.

In recent years, two important databases, one on electron and positron stopping powers and one on x-ray and

gamma-ray attenuation, have become widely used. The NIST-published collections of atomic energy levels,

transition probabilities, and collisions are being converted into PC databases.

The SRD Atomic Data Program also is responsible for work on revision of the fundamental constants including

release of the latest revision in 1986.

(301)975-5550

The NIST Database on Electron and Positron Stopping Powers and Ranges provides rapid calculation of stopping powers (collisional, radiative, and total), CSDA ranges, radiation yields and density effect corrections for

incident electrons or positrons with kinetic energies from 1 keV to 10 GeV, and for any chemically defined

target material. The interactive program allows the user to specify incident particle, energy list, target material

and density, and for a gas, temperature and pressure. Liberal help screens clearly describe the calculations.

Results can be saved to an external file for future use.

This database is available in PC diskette format. A similar database available on magnetic tape extracts

comparable information for specific materials (285 for incident electrons and 29 for positrons).

National Institute of Standards and Technology

Gaithersburg, MD 20899

(301)975-5550

This database (called XGAM) provides photon cross sections (interaction coefficients) and attenuation coefficients for any substance. Interactive software is provided which enables the user to obtain data by entering

chemical formulas or other measures of composition for a mixture of component materials. The user may also

select the energy range over which data are desired.

The system operates from a database of cross sections for coherent and incoherent scattering, photoionization,

and pair production for the elements Z = 1 to 100 at energies from 1 keV to 100 GeV. The data supplied were

obtained by a critical data analysis combining theoretical and experimental results.

The user may request data to be tabulated at the fixed energies stored in the database, at these fixed energies plus

others specified by the user, or at a completely arbitrary set of specified energies. The tabulated results include

the individual contributions and the total mass attenuation coefficient, with and without coherent scattering.

This database is available on both a PC diskette and a magnetic tape.

Collisional Alignment and Orientation of Atomic Outer Shells I. Direct Excitation by Electron and Atom Impact—

Nils Andersen, Jean W. Gallagher, and Ingolf V. Hertel. Physics Reports 165, July 1988.

Data describing the dynamics of the excited state charge cloud resulting from low-energy electron or ion impact on atomic targets are reviewed. Various research groups have used different parameterizations to express

these data acquired from observation of the polarization of radiation emitted following excitation. In this re- view, all data are reformatted into a physically meaningful set of parameters which quantify the shape and angular momentum of the excited state charge cloud. The results of similar measurements by different groups are compared, and fundamental theories are tested by comparing their predictions of the same quantities. Thus, this

work organizes and summarizes the field of collisional alignment and orientation of atomic outer shells by direct

excitation, including all data reported prior to mid-1988, and provides a foundation for future research.

CHEMICAL KINETICS

The NIST Program on Chemical Kinetics Data has long been a source of reliable, critically evaluated data on

gas-phase reactions. Over the years, data provided by the program have been instrumental in modeling and

predicting many important scientific problems such as combustion chemistry, atmospheric changes caused by

ozone depletion and warming, plasmas, and free-radical chemistry.

Recently, a comprehensive, easy-to-use PC database on over 2,000 gas-phase reactions has been widely distributed allowing scientists quick access to reaction rate data, as well as supporting information. In addition, the

Radiation Chemistry Data Center at Notre Dame University provides a biweekly literature current awareness

service on kinetics of ions, and free-radicals.

MATERIALS PROPERTIES

The NIST Materials Data Program concentrates on providing evaluated data in three areas: phase equilibria,

structure and characterization, and performance properties. Phase equilibrium data are addressed in two large

cooperative programs. The NIST/ASM Alloy Phase Diagram Program has systematically evaluated all binary

alloy phase diagrams. The NIST/American Ceramics Society Program for Phase Diagrams for Ceramists is now working on its ninth volume.

Crystallographic, electron diffraction, and surface analysis data form the bulk of the Structure and Characterization Program, and databases are available in all three areas. The databases are discussed in more detail under

Analytical Chemistry. Corrosion and tribology performance data are also cooperative activities, in conjunction

with the National Association of Corrosion Engineers and ACTIS, Inc., respectively, and several databases produced by these programs have gained wide acceptance.

THERMOCHEMISTRY

NIST has a long history as the source for reliable thermochemical data starting with the International Critical

Tables from the 1920's. The tradition continues as new SRD databases on thermochemical properties of inorganic and small organic molecules gain acceptance. The NIST Standard State Thermochemical Tables are rec- ognized as the internationally authoritative source of these data. The JANAF Thermochemical Tables contain

the most complete compilations of evaluation temperature thermodynamic data for inorganic species.

Specialized collections of data for water and aqueous electrolytes complement the standard collections. In addition, a number of detailed collections on specific families of organic and inorganic compounds are available.

NIST thermochemical databases are available both in convenient PC formats and as online systems.

This database consists of an interactive program which calculates the thermodynamic properties of fluid H2O

(liquid and vapor) using the formulation as approved by the International Association for the Properties of

Steam (lAPS) at its Tenth International Conference in 1984.

The interactive FORTRAN 77 program consists of three parts. The first part contains a package of subroutines

to calculate the thermodynamic and transport properties of fluid H2O. The other parts are maiu programs

which call these routines to generate properties of H2O interactively.

The first main program allows the calculation and display of all properties at a single pair of independent variables:

pressure - temperature

density - temperature

entropy - temperatiure

enthalpy - temperature

enthalpy - pressure

29
The second main program allows the generation of tables of properties along isotherms, isobars, or isochores.

To keep the tabular form compact, the user may choose which properties are to be displayed.

The range approved by lAPS for this formulation includes temperatures from 0 to 1000° C and pressures up to

1500 MPa. The range over which usable results will be obtained extends to 2500 K and to 3000 MPa.

The printed version of this database, which includes a description of the data selection and evaluation procedures, is found in NBS/NRC Steam Tables-L. Haar, J. S. Gallagher, and G. S. Kell. Hemisphere Press,

THERMOPHYSICAL PROPERTIES OF FLUIDS

The complexity of providing reliable data on the thermochemical and thermophysical properties of flmd mixtures has been the focus of considerable attention of the SRD Program. Over the years, a set of combined

theoretical and empirical predictive techniques have been developed that rest firmly on evaluated data. These

techniques have been tested and incorporated into interactive computer programs that will provide a large variety of properties based upon the specified composition and the appropriate state variables.

Databases are now available for hydrocarbon mixtures, including natural gas, as well as a number of pure and

mixed fluids of industrial importance.

This database (called SUPERTRAPP) is an interactive computer program for the prediction of thermodynamic

properties of mixtures which may be used for pvu^e fluids or for mixtures of up to 20 components. The components

are selected from a database of 116 components, mostly hydrocarbons. SUPERTRAPP performs phase equilibria

calculations and gives the thermodynamic properties of all phases and the feed. These results include:

Equilibrium properties Transport properties

• density * Cp • viscosity

• compressibility factor • CplCv • thermal conductivity

• enthalpy • soimd speed

• entropy • Joule-Thomson coefficient

SUPERTRAPP features commands that allow you to:

• perform bubble point pressure calculations

• perform dew point pressiu-e calculations

• perform isothermal flash calculations

• obtain properties of pure components along the saturation boundary

• produce tables of properties along isobars or isotherms

• change units

• learn (and remember) a new component not in the current database

• enter data from the keyboard or from data files

• save results in a file

This database is available in PC diskette format.

These interactive programs (called MIPROPS) compute thermophysical properties of 12 pure fluids: helium,

argon, parahydrogen, oxygen, nitrogen, nitrogen trifluoride, ethylene, methane, ethane, propane, isobutane, and

normal butane. The programs provide prompting for selection of several options including choice of fluid,

choice of units, and choice of single-phase or liquid-vapor-phase calculations.

Properties are computed for the single-phase region from input of two of the following variables: temperature,

pressure, and density. Values on the liqmd-vapor boundary are computed for either a given temperature or a given pressure. The program returns values for pressxure, temperature, density, internal energy, enthalpy, entropy, specific heats at constant volume, pressure, and sound velocity. Viscosity, thermal conductivity, and

dielectric constants are given for five of the fluids.

This database is available in PC diskette and magnetic tape format.

(303)497-3386

The NIST Mixture Property Program (DDMIX) is an interactive computer program which calculates various

thermodynamic and transport properties of mixtures of fluids selected from any of 17 possible pure components.

The emphasis of the program is on density prediction (especially for C02-rich mixtures), but it will provide

accurate results for other properties and mixtures.

All phase equilibrium calculations are performed with the Peng-Robinson (PRS) equation of state, and coexisting phase properties are calculated with the NIST extended corresponding states model (DDMIX). Mixtures

formed from any of 17 pure components (including hydrocarbons, nitrogen, oxygen, argon, carbon monoxide,

carbon dioxide, and hydrogen sulfide) are handled by the program.

DDMIX provides the following outputs for any specified mixture:

• bubble point pressure

• dew point pressure

• saturation properties

• tables of density, enthalpy, entropy, and heat capacity as functions of T or P

• isothermal flash calculation yielding density, enthalpy, entropy, heat capacity,

viscosity, and thermal conductivity of feed and vapor

This database is available in PC diskette format.
