Foreword

The National Institute of Standards and Technology (NIST), formerly the National Bureau of Standards, was created by a Congressional act in 1901 to be the source and custodian of standards for physical

measurement in the United States and charged with the responsibility for establishing a measurement

foundation to facilitate both national and international commerce. This mission was purposely stated in broad terms in order to allow the agency the flexibility to reorient its programs in response to changing

national needs and priorities. As a result of its congressionally mandated mission, first the National

Bureau of Standards and now NIST has aimed its research and service activities toward:

helping U.S. industry improve its competitiveness through new technologies, modernized

production processes, improved quality control and rapid commercialization.

At the same time, the Institute has two very important goals in serving the needs of its other major

customers — government at all levels, academia, and the general public. They are:

improving public health, safety, and the environment through selected research programs, and

conducting fundamental research that advances science and engineering.

The evolving linkage between the United States and world economy has resulted in an increased awareness of the need for comparability among data used to assess product quality and/or evaluate processes. Standard Reference Materials (SRMs) represent one mechanism by which measurement quality and traceability to national and international standards can be achieved when they are properly used. As a part of

its congressional mandate the goals of NIST are to: develop reference and definitive methods of analysis,

certify and issue standards, and assure their effective use in the measurement community, thereby helping

to achieve accurate measurements in the United States and throughout the world.

The Standard Reference Materials Program distributes over 1300 different SRMs developed and certified

in the NIST laboratories. NIST has a customer base for its standards of over 60,000 users with approximately 25% located outside the United States. All currently available SRMs are described in this Standard Reference Materials Catalog, Special Publication 260. In addition to the current stock of SRMs,

the Program will partner with customers to evaluate proposed SRMs for their potential to meet industrywide requirements, to develop SRMs based on identified needs, and issue new SRMs that will help

standardization efforts.

As the world commerce and trade markets have become more global, customers are using SRMs more to achieve conformance to process requirements and measurement quality that address international as well

as national needs for commerce and trade. All measurements using SRMs have the capability of being

traceable to a common and recognized set of standards and consequently the compatibility of laboratories can be realized.

Continued support for the SRM Program is appreciated.

Abstract and Key Words

This catalog provides technical and general ordering information for the Standard Reference Materials

(SRMs) and Reference Materials (RMs) currently available from the National Institute of Standards and

Technology (NIST) Standard Reference Materials Program (SRMP). The materials are arranged according

to technical category and classified as follows: Standard Reference Materials for Chemical Composition;

Standard Reference Materials for Physical Properties; and Standard Reference Materials for Engineering

Materials. Technical descriptions are given for all materials and may include certified values. However,

these values are incomplete as they appear in the catalog and therefore cannot be referenced for actual measurement purposes. The certificates issued by the SRMP are the only legitimate sources of certified information for NIST reference materials.

Key Words: analysis, calibration, Certified Reference Materials, characterization, composition, concentration, material, measurement, property, quality assurance, quality control, Reference Materials, Standard

Reference Materials, standardization.

NIST Policy Regarding Use of Metric (SI) Units

The following policy was established in February 1991:

"In accordance with the Metric Conversion Act of 1975 as amended by Section

5164 of the Omnibus Trade and Competitiveness Act of 1988 and as required by

related provisions of the Code of Federal Regulations, the National Institute of

Standards and Technology (NIST) will use the modem metric system of measurement

units (International System of Units — SI) in all publications. When the field of application or the special needs of users of NIST publications require the use of non-SI

units, the values of quantities will be first stated in SI units and the corresponding

values expressed in non-SI units will follow in parentheses."

The technical information contained in this catalog is consistent with the above policy. Only SI units

and symbols have been used to describe the reference materials contained herein. Therefore, abrogated or

obsolete quantifiers (i.e., the term, ppm), no longer appear, but rather have been replaced with the correct

SI term, (mg/kg), and reference material values previously expressed in only in-lb units, have been converted to the appropriate SI units [1,2]. Due to space limitations, the non-SI units converted are not shown

in the catalog.

There is one notable exception to this policy — use of the quantifier, "Wt. %". While this quantifier is not a SI unit, it is very widely used in industry and thus appears in many SRM certificates and throughout this catalog. However, in accordance with the above policy, future SRM certifications which heretofore would

have been expressed in "Wt. %", will instead be expressed as a fraction or a percent of the appropriate SI

unit which pertains to the quantity(ies) certified.

Note to SRM Users: Individual SRM certificates should be consulted to ascertain if certification data have been

expressed in both SI and non-SI units.

NIST Policy On Measurement Uncertainty Statements

The following policy was established in January 1993:

"[ ] All NIST measurement results are to be accompanied by quantitative statements

of uncertainty [1]. To ensure that such statements are consistent with each other and with

present international practice, this NIST policy adopts in substance the approach to expressing measurement uncertainty recommended by the International Committee for Weights and

Measures (CIPM)."

[The CIPM approach is based on Recommendation INC-1 (1980) of the Working Group on the State- ments of Uncertainties. More recently, at the request of the CIPM, a joint BIPM/IEC/ISO/OIML working

group developed a comprehensive reference document on the general application of the CIPM approach

[2]. The development of this document is providing further impetus to the worldwide adoption of the

CIPM approach.]

The uncertainty statements contained in certificates for SRMs produced after January 1993, are in compli- ance with the above policy. To the fullest extent possible, these certificates describe the uncertainty components associated with each certified value reported, in terms recommended by the CIPM approach. The

NIST technical division(s) that approved the certification protocol, produced the SRM, and evaluated the

certified value(s) and associated uncertainty(ies) resulting therein, are responsible for employing the statistical methods that are in accordance with this policy.

Note to SRM Users: It is essential that all statistical information contained in a NIST SRM certificate be

carefully reviewed before the certified value(s) and associated uncertainty (ies) are applied to a measurement

process or program.

How to Use This Catalog

The NIST Standard Reference Materials Catalog 1995-96 lists Standard Reference Materials (SRMs) and

Reference Materials (RMs) issued by the NIST Standard Reference Materials Program. It consists of a guide and three (3) indexes, each of which groups the SRMs and RMs according to a distinctive characteristic or descriptor. Selection of the guide or one index over another to locate the information desired will depend on the user's prior knowledge of a specific SRM or RM and intended SRM or RM application.

Guide to SRM/RM Technical Categories - This is a general listing based on the three major categories into

which all the SRMs and RMs have been assigned. The categories are divided into sequentially numbered

sections, each of which describes a material class or technical property class. The sections are further di- vided into subsections, each of which describes a specific type of material or technical property and the

physical form(s) of the SRMs and RMs contained therein. The titles of the subsections are the descriptors

for the tables comprising the catalog.

SRM/RM Subject Index -This index is based on short word descriptors (one to four words) of the SRMs

and RMs in the catalog. These descriptors may identify a section, subsection, a material class, a specific

SRM property, a specific SRM application, or a measurement technique. Some descriptors may coincidently

also identify an individual SRM or RM; however, only a few SRMs or RMs will be so described. The index

is arranged in alphabetical order of the first word of the descriptor. Because of the variety of descriptors used, some SRM and RM materials may be cross-referenced.

SRM/RM Numerical and Certificate Index -This index is based on the unique numerical identifier as- signed to each and every SRM and RM issued by NIST. This identifier is the SRM or RM Number, an in- tegral part of the reference material name which appears on each SRM certificate or RM report of

investigation. The index lists all the SRMs and RMs sequentially by this number, beginning with SRM lc and ending with RM 9529. A short word descriptor of the SRM or RM, the category subsection in which

it is assigned, and the certificate or report-of-investigation date of issue are also provided for reference.

EXAMPLE

SRM - 94c

Descriptor - Zn Base Die Casting Alloy

Certificate Date - Dec 94

Section Code - 102

Page - 46 (page no.)

SRM/RM Material Safety Data Sheet (MSDS) Index - The index is similar to the Numerical and Certifi- cate Index but it lists only those SRMs/RMs for which Material Safety Data Sheets (MSDSs) are required.

The identifier is the SRM or RM Number and the short word descriptor used in the Numerical Index.

These are followed by the MSDS Number, which usually carries the same SRM/RM number identifier,

and its date of issue . In accordance with applicable national and international regulations, a copy of the

MSDS accompanies every shipment of its relevant SRM/RM.

EXAMPLE

SRM - 1450b

Descriptor - Thermal Resistance Board

MSDS Number - 1450b

MSDS Date - Apr 92

Page - 166

Program Information

The National Institute of Standards and Technology (NIST) offers for sale over 1,300 different materials

through its Standard Reference Materials Program. These materials are primarily Standard

Reference Materials (SRMs) certified for their chemical compositions, chemical properties, or physical

properties, but also include other reference materials. All materials bear distinguishing names and

numbers by which they are permanently identified. Thus, each material bearing a given description is identical (within the specified limits) to every other sample bearing the same designation— with the

exception of individually certified items, which are further identified by serial number. #

Definitions

From "Terms and definitions used in connection with reference materials," ISO Guide 30-1992 (E):

1. "Reference Material (RM): A material or substance, one or more properties of which are

sufficiently well established to be used for the calibration of an apparatus, the assessment of a measurement method, or for assigning values to materials."

2. "Certified Reference Material (CRM): A reference material, one or more of whose property

values are certified by a technically valid procedure, accompanied by or traceable to a certificate or other documentation which is issued by a certifying body."

NIST Standard Reference Materials (SRMs): Certified reference materials issued by NIST. These are well-characterized materials produced in quantity to improve measurement science. SRMs are certified for

specific chemical or physical properties, and are issued by NIST with certificates that report the

results of the characterization and indicate the intended use of the material. They are prepared and used

for three main purposes:

(1) To help develop accurate methods of analysis (reference methods);

(2) To calibrate measurement systems used to: (a) facilitate exchange of goods,

(b) institute quality control,

(c) determine performance characteristics, or

(d) measure a property at the state-of-the-art limit; and

(3) To assure the long-term adequacy and integrity of measurement quality assurance programs.

NIST certified values are obtained by one or more of the following measurement routes:

(1) A previously validated reference method,

(2) Two or more independent, reliable measurement methods, or

(3) A network of cooperating laboratories, technically competent and thoroughly knowledgeable with

the material being tested. An in-depth discussion of the use of SRMs can be found in NIST Special Publication 260-100

"Standard Reference Materials HANDBOOK FOR SRM USERS" written by John K. Taylor (February

1993, edited by N. M. Trahey).

A number of Reference Materials (RMs) listed in this catalog are sold, but not certified, by NIST.

However, they meet the ISO definition for RMs, and many meet the definition for CRMs. The documentation issued with these materials is either a: (1) "Report of Investigation," the sole authority being the author of the report. RMs are intended to further scientific or technical research on particular materials. The principal consideration in issuing RMs is to provide a homogeneous material so that investigators in different laboratories are assured that they are investigating the same material.

(2) "Certificate," issued by the certifying agency (other than NIST), e.g., other national laboratories,

other government agencies, other standardizing bodies, or other non-profit organizations. When

deemed to be in the public interest and when alternate means of national distribution do not

exist, NIST acts as the distributor for such materials. This service is available to organizations

that qualify and have the reference materials that would help meet national measurement needs.

6
SRM Catalog

New catalogs of NIST SRMs (and RMs) are published approximately every 2 years, listing materials avail- able and renewal materials in preparation, and deleting discontinued materials. The Catalog is supplemented by Price Lists issued simultaneously with each new catalog and annually to keep the catalog current between editions. These supplements list current prices, and reflect any changes in material

availability— listing new and renewal materials and deleting discontinued ones. A guide and three indexes are provided for user convenience. They are described in the section, How

to Use This Catalog.

Preparation and Availability of SRMs

New and renewal SRMs are being prepared continually. While these SRMs are included in the next edi- tion of the catalog and its supplements, prospective users whose names are on the SRM mailing list are

also notified as soon as the new items become available. Requests for placement on the SRM mailing list can be submitted at any time to the Standard Reference Materials Program.

Renewal SRMs are intended to be completed before the supply of an existing SRM is exhausted.

However, this is not always possible and an SRM may be out of stock for a time. When this occurs, those

ordering the material are so notified and possible substitute SRMs are suggested. When a renewal is issued, customers who have ordered the previous lot are promptly notified of the price and availability of

the renewal. If little demand exists or if an alternate source of supply becomes available, production of an SRM may be discontinued permanently.

Renewal SRMs may not be identical to the preceding lot; however, they meet the same specifications

and can be used for the same purpose. For example, the first 0.1% carbon Bessemer steel was prepared

in 1909 (Standard Sample No. 8). Since then a number of renewals, 8a, 8b, 8c, etc., have been prepared.

The current SRM 8j 0.1C, represents the eleventh lot of the material. Each lot differs somewhat in detailed analysis; thus the use of the specific certificate for that lot is essential. Guide for Requesting Development of SRMs

NIST has the responsibility to develop, produce, and distribute SRMs that provide a basis for comparison

of measurements on materials, and that aid in the control of production processes. To carry out this function, the Standard Reference Materials Program evaluates the requirements of science, industry, and

government for well-characterized reference materials, and directs the production and distribution of such

materials.

To become a SRM, a candidate material must meet one or more of these criteria:

1. It would permit users to attain more accurate measurements.

2. Its production elsewhere would not be economically or technically feasible.

3. It would be an industry-wide standard for commerce from a neutral source not otherwise available

to the public.

4. Its production by NIST would assure continued availability of a well-characterized material

important to science, industry, or government.

NIST has recognized and responded to requests to enlarge the scope of the Standard Reference

Materials Program to include all types of well-characterized materials for use in calibrating measurement

systems, or for producing scientific data that can be referred to a common base. However, the requests

for new SRMs greatly exceed NIST's capacity to produce and certify such materials. Consequently,

requests for new SRMs of limited need or use are deferred in favor of requests that clearly show a

critical need. To determine which requests receive priority, NIST seeks and uses information supplied by

industry and such organizations as the American Petroleum Institute (API), American Society for Testing and Materials (ASTM), etc., to objectively assess the urgency and importance of proposed new

reference materials.

7
Requests to the Standard Reference Materials Program for the development of a new SRM should

provide the following information:

1. Short title of the proposed SRM.

2. Purpose for which the SRM would be used.

3. Reasons why the SRM is needed.

4. Technical characteristics and requirements for the material. Include additional requirements and

reasons if more than one SRM is necessary for standardization in this area.

5. Estimates of the probable present and future (5-10 years) demand for such an SRM, nationally

and internationally.

6. Justification for SRM preparation by NIST, particularly if a similar one could be produced or obtained from another source.

7. Pertinent information to aid justification for the SRM, such as: (a) an estimate of the potential

range of application, monetary significance of the measurement affected, scientific and technological significance including, when feasible, estimates of the impact upon industrial productivity,

growth, quality assurance or control, and (b) supporting letters from industry leaders, trade organizations, interested standards committees, and others.

Ordering NIST Reference Materials

General

Purchase orders (in English) for all NIST SRMs/RMs should be directed to:

National Institute of Standards and Technology

Standard Reference Materials Program

Room 204, Building 202

Gaithersburg, MD 20899-0001

USA

Telephone: (301) 975-6776

Fax: (301) 948-3730

E-Mail: SRMINFO@enh.nist.gov

Each purchase order should give the number of units, catalog number, and name of each reference

material requested.

Example: 1 each, SRM 79a, Fluorspar (Customs Grade).

The following information must be included with each order: a billing address, a shipping address, name of customer, telephone number, fax number, purchase order number, a customer identification

number, i.e., a social security number (SSN) for consumer customers, tax identification number (TIN) for commercial customers, or agency code (ALC) for U.S. government customers.

Note: NIST SRMs/RMs are only distributed in the units of issue listed in this catalog and its supplement

(price list). Also, purchase orders or inquiries submitted in a language other than English, will take

several weeks to process. Acceptance of an order does not imply acceptance of any provisions set forth in the order that are contrary to the policy, practice, or regulations of the National Institute of Standards and Technology or the

United States Government.

Out-of-Stock Materials

Orders for "out-of-stock" SRMs/RMs, are generally filled with the renewal reference materials — if available; otherwise the orders will be canceled. Customers are notified when an order is canceled and

their names are placed on a notification list. This list is used to contact customers when the reference

material (or its renewal) is again available. Upon notification, customers are told the price of the material

and are asked to submit a new order if they still wish to purchase it. For some SRMs/RMs, production lots are small and stock outages occur frequently. In these cases, the

notification list is used to fill orders on a "first come, first served" basis. Customers are contacted when

the reference materials are again available and are asked to confirm their original purchase orders.

Terms and Conditions

Prices quoted for SRMs/RMs are in U.S. dollars ($), and are published in the catalog supplement (price

list). The prices shown therein are subject to change without notice and orders will be invoiced for the

prices in effect at the time of shipment. Shipping and handling charges for regular and special (for SRMs

in restricted categories) shipments, are also applied to all orders. These charges will be added to the

invoices.

Note: A 10% discount is given on individual purchase orders for 50 or more SRM units (single SRM, or combination of SRMs).

9
Payment of all invoices is expected within 30 days of receipt for domestic orders - 45 days of receipt for foreign orders, and may be made by any of the following:

• Banker's draft against U.S.A. bank,

• Bank to bank transfer to U.S.A. bank,

• Cash against documents,

• VISA or Mastercard only,

• International money order.

Late Charges

In accordance with U.S. Treasury regulations, late charges will be levied for each 30/45-day period, or

portion thereof, that an invoice payment is overdue.

Proforma Invoice (Price Quotation)

Proforma invoice service requires 3 to 4 weeks to process and is furnished only to those customers requiring such service.

Domestic Shipments

SRM/RM shipments within the continental U.S. are shipped F.O.B. Gaithersburg, MD. There are several shipping modes which can be used, including UPS Ground, Federal Express, Roadway Package Service,

Air Freight, and Motor Freight (Collect). Unless otherwise instructed by the customer, the mode of shipment will be selected by NIST. Fewer shipping modes are available to SRMs/RMs in restricted categories

and NIST reserves the exclusive right to select the proper shipping mode for these types of shipments.

For restricted SRM/RM shipments, an additional charge is incurred for each shipping container used.

This charge is added to the invoice.

Foreign Shipments (and shipments to Alaska and Hawaii)

SRM/RM shipments outside the contiguous U.S. are also shipped F.O.B. Gaithersburg, MD by one of the

following modes, including UPS International, Federal Express International (subject to size, weight, and

category of material limitations), Air Parcel Post, and Air Freight. Unless otherwise instructed by the cus- tomer, the mode of shipment will be selected by NIST. Any other mode of shipment requested by the

customer must be paid by the customer. Fewer shipping modes are available to SRMs/RMs in restricted

categories and NIST reserves the exclusive right to select the proper shipping mode for these types of

shipments.

Restricted Shipments — Dangerous Goods (Hazardous Materials)

Some SRMs/RMs are classified as "Dangerous Goods" by the U.S. Department of Transportation (DOT),

the International Civil Aviation Organization (ICAO), or the International Air Transport Association

(IATA). These organizations have published regulations and procedures for packaging and shipping

dangerous (hazardous) goods which must be followed to safely transport these materials. Such regulations

and procedures are very specific and do not allow exceptions. NIST reserves the exclusive right to select the proper packaging and shipping mode to assure the shipments comply with these regulations and

procedures.

10
Restricted Shipments — Temperature Sensitive Materials

Some SRMs are extremely temperature-sensitive and will perish unless shipped by the most expedient

mode available. To ensure the stability of these materials, they must be packaged with Cool Packs or dry

ice which will maintain the necessary low temperatures for a short period of time. However, several SRMs

are so temperature-sensitive that they are restricted to domestic sales only, and must be shipped according to a set schedule.

Documentation (All documents are printed in English)

The documentation NIST furnishes are:

a. Commercial invoice(s),

b. Packing slip(s),

c. Air waybill for air shipments (provided UPON REQUEST ONLY),

d. NAFTA Certificate(s) (when applicable),

e. SRM/RM Certificate(s) — one (1) for each unit ordered,

f. Material Safety Data Sheet(s) — one (1) for each type or ordered material requiring it. CUSTOMERS ARE REQUIRED TO INSPECT ALL PACKAGES AND DOCUMENTATION IMMEDIATELY UPON RECEIPT OF SHIPMENT. ANY DAMAGE, SHORTAGES OR DEFECTS MUST BE

REPORTED TO SRM PROGRAM CUSTOMER RELATIONS AT (301) 975-6776, WITHIN FTVE (5) DAYS OF RECEIPT OF SHIPMENT.

Rush Shipments

Requests for rush shipments will be accommodated when possible. However, they will be made in compli- ance with existing regulations pertaining to the SRMs/RMs being shipped and when hazardous materials

are involved, all regulations governing their transportation will take precedence. The following types of

rush shipments are available:

• Same day shipping — Orders must be placed by 10:00 AM Eastern Standard Time (EST). In

addition to the normal shipping fees, a processing fee of $50.00 will be added to the customer's

invoice.

• Next day shipping — In addition to the normal shipping fees, a processing fee of $25.00 will be

added to the customer's invoice.

(Exception: Hazardous materials will not be shipped the same day.)

11
Returned Goods

NIST SRMs/RMs are generally not returnable — with the exception of defective goods or shipments

made in error by NIST. However, normal transaction of business inevitably requires the occasional return of merchandise for exchange or credit. NIST has therefore instituted the following returned goods policy:

Return shipments are accepted by NIST only after specific arrangements to do so have been

made. To return a SRM/RM, SRM Program Customer Relations must be contacted to obtain a Return Authorization Number and shipping instructions. REQUESTS FOR RETURN AUTHORIZATION MUST BE MADE WITHIN THIRTY (30) DAYS OF RECEIPT OF SHIPMENT.

Return shipments of hazardous SRMs/RMs authorized by SRM Program Customer Relations,

must be packed, marked, labeled, and shipped in accordance with national and international reg- ulations governing their transportation. Opened, leaking or damaged hazardous SRM/RM units

and/or their containers CANNOT BE RETURNED TO NIST but should be disposed of in accordance with applicable laws and regulations.

Returns which will not be authorized or accepted UNDER ANY CIRCUMSTANCES include:

• Perishable SRM/RMs,

• Unsealed, partially used, modified or mutilated SRMs/RMs,

SRM/RM Certificates and Material Safety Data Sheets

Each SRM/RM shipment contains sufficient copies of Certificates and MSDSs (if applicable) for the

number of units ordered. However, if these documents are misplaced, NIST will provide additional copies

free of charge upon request and when proof of purchase has been provided. Customers may call, fax, or

use the following e-mail addresses to send in their requests:

for Certificates — SRMCERT@enh.nist.gov

for MSDSs - SRMMSDS@enh.nist.gov

Requests will usually be processed within twenty-four (24) hours. Documents under or equalling ten (10)

pages will be faxed; documents exceeding ten (10) pages will be mailed. If the documentation is urgently

needed, the customer must provide a Federal Express account number.

NIST also provides copies of misplaced 'Archive certificates' free of charge to customers who possess NIST SRMs/RMs that are no longer for sale. This service is available on a one-time-only basis.

Other Services of the

National Institute of Standards and

Technology

Calibration and Related Measurement Services

The measurement services of NIST include calibrations, special tests, and Measurement Assurance Pro- grams (MAPs). The calibrations and MAPs of NIST satisfy the most demanding and explicit measurement

requirements, in that these services are carried out regularly under pre-established and well-defined conditions; the measurement processes involved are well-characterized, stable and in a state of statistical control; and quality control procedures are well-defined and strictly followed. These services are described in NIST Special Publication 250, Calibration Services Users Guide.

Standard Reference Data Program

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

engineers for use in technical problem-solving, research, and development. These recommended values are based on data which have been extracted from the world's literature, assessed for reliability, and then

evaluated to select the preferred values. The primary vehicles for dissemination of this data are the NIST

Standard Reference Database Series and the Journal of Physical and Chemical Reference Data (JPCRD)

.

Databases and publications are described in SP 782 - NIST Standard Reference Data Products Catalog.

Accreditation of Testing Laboratories

The National Voluntary Laboratory Accreditation Program (NVLAP) accredits public and private calibra- tion and/or testing laboratories, based on evaluation of their technical qualifications and competence for conducting specific tests or types of tests in specified fields of testing or calibration. Accreditation is based on criteria published in the Code of Federal Regulations as part of the NVLAP procedures.

Accreditation is granted following successful completion of a process which includes submission of an

application and payment of fees by the laboratory, an on-site assessment, resolution of any deficiencies

identified during the on-site assessment, participation in proficiency testing, technical evaluation, and

administrative review. The accreditation is formalized through issuance of a Certificate of Accreditation

and Scope of Accreditation as publicized by announcement in various government and private media.

Application packages may be obtained from:

This series of SRMs was produced through a cooperative program between NIST and the Institute for Non-Ferrous Metals (IMN), Gliwice, Poland and funded under the auspices of the Second Maria

Sklodowska-Curie Fund. Development, characterization and certification of the monolithic brasses were

carried out by the IMN; homogeneity testing was performed by NIST. A detailed technical discussion

of these SRMs will be given in a Special Publication due to be published in mid-1995. Each SRM unit is in the form of disk, ~ 39.5 mm in diameter and 20 mm thick.

104. Spectrometry, Multi-Element (solution form)

SRMs 3171a and 3172a consist of single 50-mL solutions, each containing several elements in concentration

ratios appropriate for natural water and similar type sample analysis. Multi-element SRM 3179 consists of a

set of three 50-mL solutions, (3179-1, 3179-11 and 3179-III), designed to be combined, diluted (I, 1:100;

II and III, 1:1000) and used immediately, as the full combination of elements is unstable over extended

periods of time. The elemental concentration ratios in the final combined and diluted solution of SRM 3179

are appropriate for the analysis of soil, sediment and sludge leachates.

These Reference Materials, RMs 8491 Sugar Cane Bagasse (Saccharum spp. hybrid), 8492 Eastern Cottonwood (P. deltoides ), 8493 Pinus Radiata, and 8494 Wheat Straw (Triticum aestivum ) are intended primarily

for use in fundamental studies on the chemical and physical properties of cellulose, hemi-cellulose and

lignin and of their effects on various conversion processes. As part of the International Energy Agency

(IEA) Voluntary Standards Activity Group's work, these materials were selected initially for use as research

materials for a world-wide round robin analytical laboratory comparison using the Uppsala Method. They

were supplied by various institutions and were prepared, packaged and are being distributed by NIST.

At this time, no extensive property measurements have been made on these materials beyond ensuring

that the materials are homogeneous. A round robin is in progress with participation by international

laboratories and as results become available, the Report of Investigation that accompanies each of these

materials will be revised to reflect those changes.

All of the ground and homogenized materials were irradiated with Cobalt-60. The irradiation was

required to meet customs regulations for shipment of biomass materials to international destinations.

202. Rubbers and Rubber Compounding Materials (powder and solid forms)

These SRMs have been prepared to provide the rubber industry with standard materials for rubber

compounding. They are useful for the testing of rubber and rubber compounding materials in connection with

quality control of raw materials and for the standardization of rubber testing.

Each material has been statistically evaluated for uniformity by mixing rubber and rubber compounds, vul- canizing them in accordance with ASTM Designation D-3182 and determining the stress-strain properties of

the resulting vulcanizates. A certificate is issued for the rubber SRM 386k, because the properties of different

lots are not the same. Replacement lots of rubber compounding SRMs 371h, 372i, and 383a, impart essentially

the same characteristics to rubber vulcanizates so that certificates are not issued for these SRMs.

203. Differential Thermal Analysis (liquid and solid forms)

In cooperation with the International Confederation of Thermal Analysis and Calorimetry (ICTAC), NIST

distributes transition point, melting point and magnetic transition measurement Reference Materials (RMs)

8754, 8757, 8758, 8759, 8760, and 8761 for use with differential thermal analyzers, differential scanning

calorimeters, and thermogravimetry apparatus. These RMs (except for RM 8754) are configured in sets consisting of four or more materials in varying quantities per unit.

The ICTAC has recently undertaken a complete reevaluation of all the materials comprising these RMs and

it is anticipated that the RMs will be redistributed in the future, as single material units rather than in sets. Therefore, only limited quantities of the current RMs are still available. Information about RM status can be obtained by contacting the SRMP Sales Office.

204. Optical Properties

Molecular Absorption and Molecular Luminescence (film, filter, solid, and solution forms)

The optical SRMs for spectrophotometry are certified transfer standards that fall into three (3) general

categories — transmittance, wavelength, and stray radiant energy— each of which addresses a specific instru- mental parameter of an ultraviolet/visible absorption spectrometer that must be in control for accurate

optical transmittance measurements. To obtain optimum verification results, each SRM must be used

within the specified range of conditions for which it is intended.

SRM 930e: This SRM is for the verification and calibration of the transmittance and absorbance scales of visible absorption spectrometers. It differs from the prior series, SRM 930d, only with respect to tightened optical polishing tolerances. SRM 930e has been polished to a parallelism of two arc seconds or

better, in such a way so as to reduce the optical deviation (relative to SRM 930d) and improve perfor- mance in instruments for which wavelength dispersion occurs after the light has passed through the filter. SRM 930e consists of three (3) individual Schott NG-type glass filters in separate metal cuvette-style

holders and an empty filter holder. The nominal percent transmittances of the three filters are 10 % T,

20 % T, and 30 % T. The three filters are individually certified for transmittance at five (5) wavelengths in the visible spectrum: 440.0 nm, 465.0 nm, 546.1 nm, 590.0 nm, and 635.0 nm. The optical transmittance

neutrality of SRM 930e is sufficient for the filters to be used to accurately verify absorption spectrometers

with maximum spectral bandpasses ranging from 2.2 nm to 6.5 nm for the five wavelengths at which the

transmittances are certified. When SRM 930e is used in combination with SRM 1930, a 6-point stepwise

verification of the transmittance scale is possible over the transmittance range from 1 % T to 50 % T. A

detailed discussion of this SRM and SRM 1930 are given in Special Publication 260-116 which accompanies each unit. SRM 93 le: This SRM is for the verification and calibration of the absorbance scales of ultraviolet and

visible absorption spectrometers having narrow spectral bandpasses. SRM 931e consists of three (3) sets of

four (4) solutions in sealed 10-mL ampules. The four solutions include a blank solution and three concentrations of an empirical inorganic solution prepared from high-purity cobalt and nickel metals dissolved in a mixture of nitric and perchloric acids. The user must transfer the blank and standard solutions to cuvettes of known pathlength. The spectrum has absorption maxima at 302 nm, 395 nm, and 512 nm, and a plateau in the region of 678 nm at which the absorbances are certified. The nominal absorbances of the

three empirical inorganic solution standards are 0.3, 0.6 and 0.9, respectively, at wavelengths 302 nm,

395 nm, and 512 nm. At wavelength 678 nm, the nominal absorbances of the three solutions are 0.1, 0.2, and 0.3, respectively. The liquid filters may be used to verify absorption spectrometers with maximum

spectral bandpasses ranging from 1.5 nm to 8.5 nm for the four wavelengths at which the absorbances are

certified. SRM 935a: This SRM is for the verification and calibration of the absorbance scales of ultraviolet absorption spectrometers having spectral bandpasses not exceeding 2 nm. Issued in 15-g units, SRM 935a

consists of crystalline potassium dichromate of established purity. Solutions of ten (10) known concentrations of this SRM in 0.001 N perchloric acid (between 20 mg/kg and 200 mg/kg) are certified for their

specific absorbances under well-defined conditions. The user must prepare the liquid solutions from SRM

935a and then transfer them to cuvettes of known pathlength. The certified specific absorbances for the

solutions prepared may be converted to their corresponding reference absorbance values using Beer's Law.

Acidic SRM 935a solutions may be prepared anywhere within the concentration range of 20 mg/kg to 200 mg/kg to provide a standard with the desired absorbance at a specified wavelength. The spectrum has

absorption maxima at 257 nm and 350 nm, and absorption minima at 235 nm and 313 nm at which the

specific absorbance values are certified, and also at 345 nm, near one of the predicted isobestic points of

the spectrum. A detailed discussion of this SRM is given in Special Publication 260-54 which accompanies

each unit. SRM 936a: This SRM is for use in the evaluation of methods and the calibration of fluorescence spec- trometers. Issued in 1-g units, SRM 936 consists of solid quinine sulfate dihydrate. It is certified for the

relative molecular emission spectrum, E(X), in radiometric units for a solution of 1.28 xlO-6 mol/L

quinine sulfate dihydrate in 0.105 mol/L perchloric acid using an excitation wavelength of 347.5 nm. The

values of the molecular emission spectrum are certified at 5-nm wavelength intervals from 375 nm to 675 nm. The user must prepare the solution and transfer it to a cuvette of known pathlength. A detailed

discussion of this SRM is given in Special Publication 260-64.

104
SRM 1921: This SRM is for use in the calibration of the wavelength scale of spectrometers in the

infrared (IR) spectral region from 3 u.m to 18 u.m (540 cm to 3200 cm

-1

). SRM 1921 consists of five (5)

cards made of a matte finish polystyrene film, approximately 38 jim thick with a 25-mm diameter clear aperture and centered 38 mm from the bottom of a cardboard holder 5 cm x 11 cm x 2 mm in size. The

certified wavelength values, corresponding peak wavenumber values for thirteen (13) absorption peak

positions in the 3 |xm to 18 n,m range and a spectrum marked with arrows identifying the certified peaks,

are provided with each unit. A detailed discussion of this SRM is given in Special Publication 260-122.

SRM 1930: This SRM complements SRM 930e for the verification and calibration of the transmittance

and absorbance scales of visible absorption spectrometers. SRM 1930 consists of three (3) individual

Schott NG-type glass filters in separate metal cuvette-style holders and an empty filter holder. The nominal percent transmittances of the three filters are 1 % T, 3 % T, and 50 % T. The three filters are individ- ually certified for transmittance at five (5) wavelengths in the visible spectrum: 440.0 nm, 465.0 nm,

546.1 nm, 590.0 nm, and 635.0 nm. The optical transmittance neutrality of SRM 1930 is sufficient for the

filters to be used to accurately verify absorption spectrometers with maximum spectral bandpasses ranging

from 2.2 nm to 6.5 nm for the five wavelengths at which the transmittances are certified. When SRM 1930

is used in combination with SRM 930d, a 6-point stepwise verification of the transmittance scale is possi- ble over the transmittance range from 1 % T to 50 % T. A detailed discussion of this SRM and SRM 930

is given in Special Publication 260-116 which accompanies each unit. SRM 1931: This SRM is for use in the evaluation and calibration of the relative spectral response of

fluorescence spectrometers. It consists of four fluorescence standards and a "blank" specimen mounted in anodized aluminum cuvette-sized holders. The standards are composed of inorganic phosphors in a sintered polytetrafluoroethylene matrix. The fluorescence standards are certified for the relative corrected

emission spectrum, E(X), in energy/wavelength units. The values of the blue (400 nm to 550 nm), green

(490 nm to 600 nm), yellow (490 nm to 740 nm) and orange (530 nm to 740 nm) emission spectra are certi- fied at 2-nm wavelength intervals. SRM 1931 L and R are oriented for left- and right-handed fluorescence

spectrometers, respectively, as defined by viewing the fluorescent sample along the excitation beam. If the

first emission optical component is located to the right of the sample then this orientation is designated

R, and if it is to the left then it is designated L. SRM 2030a: This SRM is for use in the one-point verification of the transmittance and absorbance

scales of spectrophotometers at the given wavelength and measured transmittance. SRM 2030a consists of one (1) glass filter in its holder and one (1) empty holder. The exposed surface of the glass is approximately 29 mmx8 mm, measured from a point 1.5 mm above the base of the filter holder. The filter bears an identification number. The certified transmittance value at a wavelength of 465.0 nm and for a maximum spectral bandpass of 2.7 nm is provided for each unit. The value and uncertainty are unique to each

unit and cover a period of two (2) years from date of certification. The uncertainty estimation is described in Special Publication 260-116.

SRM 2031: This SRM is for the verification and calibration of the transmittance and absorbance scales of ultraviolet and visible absorption spectrometers. SRM 2031 consists of three (3) individual non-fluorescent, fused-silica filters in separate metal cuvette-style holders and an empty filter holder. The nominal

percent transmittances of the three filters are 10 % T, 30 % T, and 90 % T. The quartz base plates of the

10 % T and 30 % T filters carry different thicknesses of semi-transparent chromium metal that are optically contacted to quartz cover plates. The nominal 90%T filter is a single clear quartz plate. The three

filters are individually certified for transmittances at ten (10) wavelengths in the ultraviolet and visible spectral regions: 250.0 nm, 280.0 nm, 340 nm, 360.0 nm, 400.0 nm, 465.0 nm, 500.0 nm, 546.1 nm, 590.0 nm,

and 635.0 nm. The optical transmittance neutrality of SRM 2031 is such that wider spectral bandpasses can be used. Consequently, SRM 2031 is the only transmittance SRM that is suitable for use with those

absorption spectrometers with large spectral bandpasses, e.g., 8 nm to 20 nm. A detailed discussion of this SRM is given in Special Publication 260-68.

105
NOTE: Because the 10 % T and 30 % T chromium-coated filters attenuate incident radiation by reflection to a large extent, SRM 2031 may possibly generate interreflections between optical surfaces in the sample

compartment of some absorption spectrometers. Such interreflections may result in isochromatic stray

radiant energy that affects the accuracy of the transmittance measurement. Consequently, when contemplating the purchase of SRM 2031, the user should contact the instrument manufacturer to verify that metal-on-quartz filters are compatible with the spectrometer.

SRM 2032: This SRM is for use in the assessment of heterochromatic stray radiation energy (stray light) in ultraviolet absorption spectrometers in the spectral region below 260 nm. Issued in 25-g units, SRM

2032 consists of reagent-grade crystalline potassium iodide (KI). Solutions of this SRM in distilled water

are certified for their specific absorbances under well-defined conditions at 240 nm, 245 nm, 250 nm,

255 nm, 260 nm, 265 nm, 270 nm, and 275 nm. The KI solutions exhibit sharp cutoffs in transmittances below about 260 nm. The user must prepare a liquid KI solution from SRM 2032 and then transfer it to a cuvette of known pathlength. The certified specific absorbance for the solution prepared is then converted

to its corresponding reference transmittance or absorbance value using Beer's Law. The amount of heterochromatic stray light in the absorption spectrometer at a wavelength below 260 nm may be determined

from the equations given in the certificate. SRM 2034: This SRM is for use in the verification and calibration of the wavelength scale of ultraviolet and visible absorption spectrometers having nominal spectral bandwidths not exceeding 3 nm. SRM 2034,

a liquid consisting of 4% (w/v) holmium oxide in an aqueous solution of 10% (v/v) perchloric acid, is sealed in a non-fluorescent, fused-silica cuvette of optical quality. SRM 2034 is batch-certified for wavelength location of minimum transmittance of 14 bands in the spectral range from 240 nm to 650 nm for six spectral bandwidths from 0.1 nm to 3 nm. A detailed discussion of this SRM is given in Special Publication 260-102 which accompanies each unit.

concentrations are about an order of magnitude higher than typical world-wide levels. Approximately

10% of the plutonium is in a acid-resistant form. The material also contains "hot" particles and a statistical method is provided for dealing with these. Inhomogeneities, excluding hot particles, are on the order of 3%

or better. SRM 4354 -Freshwater Lake Sediment

This material (gyttja) contains approximately 25 g of freeze-dried, pulverized freshwater lake sediment

(approximately 50% organic by weight) in a polyethylene bottle. The SRM is intended for use in tests of

measurements of environmental radioactivity contained in matrices similar to the sample, for evaluating

The NIST Automated Time Service (ACTS) is a telephone time service designed to provide computers with

telephone access to NIST time at occurrences approaching 1 millisecond (0.001 s). Features of the

service include automated compensation for telephone-line delay, advanced alert for changes to and from

daylight savings time and advanced notice of insertion of leap seconds. The ASCII-character time code

should operate with standard modems and most computer systems. While the system can be used to set up

computer time-of-day, simple hardware can be developed to set non-computer clock systems. The telephone

number for ACTS is (303) 494-4774.

These Reference Materials, RMs 8495 Northern Softwood Bleached Kraft Pulp and 8496 Eucalyptus Hardwood Bleached Kraft Pulp, are intended primarily for use in fundamental studies on the physical properties

of fibers and paper sheets. The materials selected for these two RMs are bleached dried lap pulp, each

from a single lot of a standard commercial production run. The materials were selected because of their dif- fering fiber size, differing papermaking properties, and similarity to commercially available materials.

RMs 8495 and 8496 were developed and prepared with input and support from the Pulp Material

Research Committee (PMRC), a sub-committee of the Fundamental Research Committee. These materials were donated by industry and are being distributed by the Standard Reference Materials Program. At this time, no extensive property measurements have been made on these materials beyond ensuring they were

within the control limits of the normal production run. A measurement error study is in progress with

participation by international paper technical laboratories. As results become available, they will be published and added to the Report of Investigation that accompanies each of these materials.

Numerical MSDS Index

The following is a listing of Material Safety Data Sheets (MSDSs) for compounds that have been determined to be hazardous by

the National Institute of Standards and Technology. Under current OSHA regulations, there is no expiration date associated with a MSDS. Materials not considered to require an MSDS, fall into one of the following categories:

1. The SRM is an article, as the word is defined in paragraph (c) of section 19.10.1200 of the title 29 of the Code of Federal

Regulations, which does not release or otherwise result in exposure to a hazardous chemical, under normal conditions and use.

2. The SRM has been determined to be non-hazardous by the National Institute of Standards and Technology under

paragraph (d) of section 1910.1200 title 29 of the Code of Federal Regulations. The SRM will not release or otherwise

result in exposure to a hazardous chemical under normal conditions of use.

3. The SRM is a pesticide or hazardous waste labeled according to regulations issued by the Environmental Protection Agency.

4. The SRM is a food, food additive, drug or clinical material labeled according to regulations issued by the Food and Drug

Administration.

5. The SRM is a wine labeled according to regulations issued by the Bureau of Alcohol, Tobacco and Firearms.

6. The SRM is a tobacco product, wood or wood product which is exempted by paragraph (b)(5)(H) and (iii) of section 1910.1200 of title 29 of the Code of Federal Regulations from the provisions of that section.

7. The SRM was obsoleted before MSDS regulations came into effect.
