Foreword

Historically, Standard Reference Materials (SRMs) have been used as vehicles for transferring National Institute

of Standards and Technology (formerly National Bureau of Standards) measurement science and technology

through channels of industry and commerce, to the country at large. Each new SRM is the result of collaboration between NIST and representatives of science and industry. SRMs are crucial reference points in establishing a comprehensive measurement system for the whole nation. Such a system, which has incrementally improved

throughout the years, has met the needs of U.S. industry and commerce for nearly 100 years and continues to evolve as it is called upon to meet more increasing demands in measurements. The fast pace of technological

change, coupled with increased demands on quality, traceability and SRM types, are making the perpetuation of

the existing system into the future a very challenging proposition.

We must take advantage of new quality management concepts and scientific and technological opportunities

which will lead to improvements in the transfer of NIST technology through SRMs. The SRM Program

increasingly is using collaborations with industry that will enable NIST to expand the coverage of measurement

needs by providing more new reference materials which have been coupled to a strategy of benchmarking a

particular measurement system with fewer SRMs. Consequently, NIST will only renew existing SRMs that

have been strategically planned and justified. This will allow NIST resources to be more effectively directed to measurement areas of anticipated high economic need or impact.

The SRMs available in this new 1998-99 catalog are reflections of some of the above strategies as well as our

efforts to fill needs as rapidly as they can be identified. Increasingly, science and industry are calling for

more units of existing SRMs for expanding fields such as optical radiation measurements, telecommunications,

aerospace industries, and national problems such as air and water pollution, and health. This catalog contains

new SRMs in all of these areas.

The Program's emphasis will continue to be on providing NIST SRMs —

• where attainment of needed measurement accuracy is not economically or technically feasible

elsewhere,

• where industry-wide standards for commerce are needed from a neutral supplier not otherwise

available,

• where continuing availability of a highly characterized material from a common source is important to science or industry.

The SRM Program invites you to review the 1998-99 catalog edition to see if any of the available SRMs can be

of use to your measurement system. Also, take a moment to provide feedback to me as to your measurements

and reference materials needs.

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 (SRM) Program. The materials are arranged according to technical category and classified as follows:

• Standard Reference Materials for Chemical Composition;

• Standard Reference Materials for Physical Properties;

• Standard Reference Materials for Engineering Materials.

Technical descriptions are given for all materials and may include certified values. However, these values are in- complete as they appear in the catalog and therefore cannot be referenced for actual measurement purposes. The

certificates issued by the SRM Program are the only legitimate sources of certified information for NIST reference

materials.

Key Words: analysis, calibration, certified reference material (CRM), characterization, composition, concentration, material, measurement, property, quality assurance, quality control, reference material (RM), Standard Reference

Material (SRM), standardization, traceability.

N1ST 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 modern 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 (e.g.,

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.

In accordance with the above policy, this edition of the catalog no longer references the abrogated quantifier, "Wt. %."

This quantifier has been replaced with the appropriate SI quantifiers, such as "mass fraction, in %", "amount-of-substance fraction, in %", or "mole fraction, in %." The exclusive use of SI quantifiers for expressing NIST SRM and RM

certified, reference, and information values was instituted by the SRM Program and the NIST technical divisions in 1995 and apply to all SRM certificates and RM Reports of Investigation issued since that time. However, the certifi- cates for SRMs issued before 1995 still show certified values expressed in "Wt. %." These certificates will not be revised. Rather, the appropriate SI quantifiers will be referenced when new certificates are generated for future renewal

issues of these SRMs.

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 Statements 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 compliance 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.

Program Information

Through the SRM Program, NIST provides more than 1200 different SRMs that are certified for their specific

chemical or physical properties. SRMs are used for three main purposes: to help develop accurate methods of

analysis (reference methods); to calibrate measurement systems; and to assure the long-term adequacy and integrity

of measurement quality assurance programs. NIST SRMs also constitute part of the National Measurement System

infrastructure of the United States and, as such, are essential transfer mechanisms for national and international

measurement traceability.

The SRM Program itself is the central point at NIST for coordination of all reference materials services and related

activities. In this capacity, the Program 1) performs continuous analysis and needs assessment of national reference

materials and requirements 2) establishes and promotes uniform criteria for the development and certification of

reference materials, 3) performs technical activities related to the preparation, packaging, and distribution of SRMs,

4) prepares and updates the SP 260 Standard Reference Materials Catalog and its price list supplement, 5) publishes

and issues a variety of other documents and articles such as journal articles, brochures, and newsletters, 6) provides

independent review of the SRM value assignment process, 7) establishes jointly with NIST technical divisions, vertical traceability links with the U.S. secondary reference materials producers, 8) provides customer support to purchasers and users of SRMs, 9) provides official NIST representation on national and international standards

committees, 10) coordinates international activities involving reference materials intercomparisons and collaborative

efforts to demonstrate reference material compatibility.

The SRM Program sponsors a series of publications, known as the SP 260 series, that is available to assist users in

the application of SRMs. Some of these publications give practical guidance for using SRMs while others give

additional information about the certification process of specific SRMs. Of special note is NIST Special Publication

260-100, Standard Reference Materials Handbook for SRM Users, by John K. Taylor, that was written to present

general concepts of precision and accuracy as applied to SRMs and to discuss their impact on quality assurance and

measurement processes.

DeHnitions

The SRM Program references a number of definitions in connection with the production, certification, and use of its SRMs and RMs. Certain definitions, adopted for SRM use, are derived from international guides and standards on

reference materials and measurements while others have been developed by the SRM Program to describe those activities unique to NIST operations. A listing of NIST-adopted and NIST-developed definitions follows.

Accuracy — (1) The closeness of agreement between a test result and the accepted reference value. [ISO 5725-1]

(2) Closeness of the agreement between the result of a measurement and a true value of the measurand. "Accuracy"

is a qualitative concept. [VIM: J 993]

Certified reference material — Reference material, accompanied by a certificate, one or more of whose property

values are certified by a procedure which establishes its traceability to an accurate realization of the unit in which

the property values are expressed, and for which each certified value is accompanied by an uncertainty at a stated

level of confidence. [ISO Guide 30:1992]

4
Reference material — Material or substance one or more of whose property values are sufficiently homogeneous,

stable, and well established to be used for the calibration of an apparatus, the assessment of a measurement method,

or for assigning values to materials. [ISO Guide 30:1992]

Reference material certificate — Document accompanying a certified reference material stating one or more property values and their uncertainties, and confirming that the necessary procedures have been carried out to ensure

their validity and traceability. [ISO Guide 30:1992]

Uncertainty of a certified value — (1) Estimate attached to a certified value of a quantity which characterizes the

range of values within which the "true value" is asserted to lie with a stated level of confidence. [ISO Guide

30:1992] (2) Parameter, associated with the result of a measurement, that characterizes the dispersion of the

values that could reasonably be attributed to the measurand. [VIM: 1 993]

Traceability — Property of the result of a measurement or the value of a standard whereby it can be related to

stated references, usually national or international standards, through an unbroken chain of comparisons all having

stated uncertainties.

1 . The concept is often expressed by the adjective "traceable."

2. The unbroken chain of comparisons is often called a "traceability chain". [VIM:1993]

a. This definition applies both to physical and chemical measurements.

b. Traceability only exists when metrological evidence, appropriate for the application, is collected on a continuing basis to document the traceability chain and quantify its associated measurement

uncertainties.

c. In most cases, the ultimate stated reference for a measurement result is the SI definition of the

appropriate unit(s). [NORAMET Document No. 7 (1995-11-13)]

NIST Standard Reference Material® (SRM®) — Certified reference material (CRM) issued by NIST. A SRM is a well-characterized material produced in quantity to improve measurement science. It is certified for specific

chemical or physical properties, and is issued by NIST with a certificate that reports the results of the characterization and indicates the intended use of the material. A SRM is prepared and used for three main purposes:

1. To help develop accurate methods of analysis;

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 Reference Material (RM) — Material issued by NIST with a report of investigation instead of a

certificate to:

1. Further scientific or technical research;

2. Determine the efficacy of a prototype reference material;

3. Provide a homogeneous and stable material so that investigators in different laboratories can be assured

that they are investigating the same material;

4. Assure availability when a material produced and certified by an organization other than NIST, is deemed to be in the public interest or when an alternate means of national distribution does not exist. NOTE: A NIST RM meets the ISO definition for a RM and may meet the ISO definition for a CRM (depending on

the organization that produced it).

5
NIST Traceable Reference Material (NTRM) — A commercially produced reference material with a welldefined traceability linkage to existing NIST standards for measurements. This traceability linkage is established via

criteria and protocols defined by NIST to meet the needs of the metrological community to be served. (Commercial

reference materials producers will be allowed to affix the "NTRM" trademark to materials produced according to these criteria and protocols.) NOTE: A NIST NTRM may be recognized by a regulatory authority as being equivalent to a CRM.

NIST certified value — Value and its uncertainty assigned by NIST in conformance with the NIST uncertainty

policy. A NIST certified value is obtained by one or more of the following measurement modes:

1. A definitive (or primary) method using specialized instrumentation capable of high accuracy and precision

and whose errors have been thoroughly investigated and corrected; or,

2. Two or more independent methods at NIST using commercial instrumentation that is calibration based and

with differing sources of systematic errors; or,

3. Interlaboratory data from selected laboratories using multiple methods and NIST SRMs as controls.

NOTE: The sources of error with this mode will generally result in uncertainties greater than those for the

other two modes.

NIST noncertified values — Values that do not meet the criteria for NIST certified values. Such values may be

referred to as NIST reference values or NIST information values. NOTE: Noncertified values are often upgraded

to certified values after additional measurements are performed and/or improved methodologies are applied.

• NIST reference values — Noncertified values with associated uncertainties that reflect only the precision

of the measurement, do not include all sources of uncertainty, or reflect a lack of sufficient statistical agreement among multiple methods. Reference values may also be the results of analyses that are method-dependent.

• NIST information values — Noncertified values with no uncertainties reported or with estimated uncertainties for which there is insufficient information to make an assessment of the uncertainties. NOTE: Information values are often simply intended to provide additional descriptive information about a material.

NIST SRM Certificate (and Certificate of Analysis) — Document stating the intended purpose and application of

a SRM, its certified property value(s) with associated uncertainty(ies), and any other technical information deemed

necessary for its proper use. In accordance with ISO Guide 31 :1996, a NIST SRM certificate bears the logo of the

U.S. Department of Commerce, the name of NIST as certifying body, and the name and title of the NIST officer

authorized to accept responsibility for its contents. NOTE 1: A SRM certified for one or more specific physical or engineering performance properties is issued with a Certificate; A SRM certified for one or more specific

chemical properties is issued with a Certificate of Analysis. NOTE 2: A SRM certificate may contain NIST

reference and/or information values in addition to certified values.

NIST Certificate of Traceability — Document stating the purpose, protocols, and measurement pathways that

support claims by a NTRM to specific NIST standards or stated references. There are no NIST certified values

provided in a certificate of traceability. Rather, the document references a specific NIST report of analysis. A NIST

certificate of traceability bears the logo of the U.S. Department of Commerce, the name of NIST as certifying

body, and the name and title of the NIST officer authorized to accept responsibility for its contents.

NIST RM Report of Investigation — Document issued with a RM and containing all the technical information

necessary for proper use of the material. There are no NIST certified values provided in a report of investigation

and authorship of a report's contents may be an organization other than NIST. A NIST RM Report of Investigation

bears the logo of the U.S. Department of Commerce and the name and title of the NIST officer authorized to

issue it.

6
The SRM/RM Identification System

The SRM Program offers for sale over 1200 different materials and adds 20 to 30 new materials as well as over one

hundred renewal materials to its inventory each year. These materials all bear distinguishing names, numbers, and

letters by which they are permanently and uniquely identified. The purpose of such identifiers is to clearly describe

each and every material and, at the same time, systematically differentiate one from the other. The following certifi- cate headings illustrate "what's in the SRM or RM name."

For convenience, the acronyms "SRM®", "RM", and "NTRM" are preferentially used in conjunction with the

primary numerical identifiers (including renewal letters - if applicable), to describe all NIST reference materials.

This catalog and its supplement are no exceptions; thus, the reference materials described herein, are identified by

their "short" tjtles (e.g., "SRM 3102a") rather than by their "long" titles (e.g., "Standard Reference Material®

3102a"). Thesk short titles preserve the unique identifications of the materials involved and should be used in lieu of

"catalog numbers" when ordering NIST reference materials.

7
Preparation and Availability of SRMs

New and renewal SRMs are being prepared continually. While these SRMs are included in the next edition 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 SRM Program Sales Office.

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

is not always possible and a 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 a 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 O.IC,

represents the eleventh issue of the material. Each issue differs somewhat in detailed analysis; thus the use of the

specific certificate for SRM 8j 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 SRM

Program evaluates the needs and 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 the following 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 recognizes and responds to requests to enlarge the scope of the SRM 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 technological or regulatory need and significant industrial and/ or metrological impact. To

determine which requests receive priority, NIST seeks and uses information supplied by industry, academia, governmental agencies, and such voluntary standards development organizations as the American Society for Testing and

Materials (ASTM), etc., to objectively assess the urgency and importance of proposed new reference materials.

8
Requests to the SRM 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. Additional requirements and reasons if more

than one SRM is necessary for standardization in this area, should be included.

5. Estimates of the probable present and future (5 to 10 years) demand for such a 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(s) 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.

SRM Catalog

New catalogs of NIST SRMs and RMs are published approximately every 2 years, listing materials available 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 following section,

How to Use This Catalog.

The NIST Standard Reference Materials Catalog 1998-99 lists Standard Reference Materials (SRMs) and Reference

Materials (RMs) issued by the NIST SRM Program. It consists of a guide and three 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 divided 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.

identifier is the SRM or RM Number, an integral 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 Ic and ending with RM 8761. 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.

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 accor- dance with applicable national and international regulations, a copy of the MSDS accompanies every shipment of its relevant SRM/RM.

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 policies, practices, 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).

13
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,

• DISCOVER, MasterCard, and VISA,

• 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 United States are shipped F.O.B. Gaithersburg, MD. There are several

shipping modes which can be used, including UPS Ground, Federal Express, 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 United States 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), and Air Freight. Unless otherwise instructed by the customer, 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 (lATA). 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 that

shipments comply with these regulations and procedures.

14
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 for each unit ordered,

f. Material Safety Data Sheet(s) — one for each type of ordered material requiring it.

SRM/RM Certificates and Material Safety Data Sheets

Each SRM/RM shipment contains sufficient copies of Certificates and Material Safety Data Sheets (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@nist.gov

for MSDSs — srmmsds@nist.gov

Requests will usually be processed within 24 hours. Documents under or equalling ten pages will be faxed;

documents exceeding ten 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.

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 SERVICE AT (301) 975-6776, WITHIN FIVE DAYS OF RECEIPT OF

SHIPMENT.

15
Rush Shipments

Requests for rush shipments will be accommodated when possible. However, they will be made in compliance 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.)

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, contact the SRM Program Sales Office to obtain a Return Authorization Number

and shipping instructions. REQUESTS FOR RETURN AUTHORIZATION MUST BE MADE WITHIN

30 DAYS OF RECEIPT OF SHIPMENT.

• Return shipments of hazardous SRMs/RMs authorized by SRM Program Sales Office, must be packed,

marked, labeled, and shipped in accordance with national and international regulations 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,

The following four series of SRMs were 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 these brasses were carried out by IMN; homogeneity

testing was performed by NIST. SRMs 1 776 through 1 280 are in the form of disks approximately 39.5 mm diameter

and 20 mm thick; SRMs 1781 through 1785 are in the form of disks 39 mm diameter and 19 mm thick; SRMs 1786

through 1790 are in the form of disks 39 mm diameter and 25 mm thick; SRMs 1791 through 1795 are in the form

of disks 38 mm diameter and 24 mm thick.

NOTE: Certification data for the Free Cutting Brasses, and Gilding Metals are concurrently undergoing review at the

IMN and NIST. Therefore, when the Certificates of Analysis for these materials are issued, the actual certified

values may differ from the "projected" values listed below.

appropriate for natural water and similar type sample analysis. 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.

107. Primary Gas Mixtures

These SRMs are for calibrating equipment and apparatus used to measure various components of gas mixtures and

atmospheric pollutants. The typical gas mixture is supplied in a DOT 3AL specification aluminum (6061 alloy)

cylinder with a nominal pressure exceeding 12.4 mPa that provides the user with approximately 0.73 m"* of usable

mixture. Due to increasing customer demand, these primary gas mixtures are in short supply and may not be readily

available for sale. In such cases, a NIST traceable reference gas described below may be substituted.

A NIST Traceable Reference Material (NTRM) is a reference material produced by a commercial supplier with a well-defined traceability to NIST. This traceability is established via criteria and protocols defined by NIST that are

tailored to meet the needs of the metrological community to be served. The NTRM concept was established to allow NIST

to respond to the increasing needs for high quality reference materials by leveraging its relatively fixed human and financial resources with secondary reference material producers. Reference material producers adhering to NIST defined

protocol requirements are allowed to use the "NTRM" trademark to identify their product.

The gas NTRM program was established in 1992 in partnership with the U.S. ER\ and specialty gas companies as a means for providing end-users with the wide variety of certified gas standards needed to implement the "Emissions

Trading" provision of the 1990 Clean Air Act. Gas NTRMs are produced and distributed by specialty gas companies

with NIST oversight of the production and maintenance, and direct involvement in the analysis. NTRMs can be

developed for any pollutant, concentration, and balance gas combination for which a NIST primary standard or SRM exists. The gas standards prepared according to this program are related, within known limits of uncertainty , to specific gaseous

primary standards maintained by NIST.

Those SRMs that are marked "t" are available as NTRMs from commercial suppliers. A supplier list can be obtained

upon request from the SRM Program Sales Office.

Alcohols and Ethers [Oxygenates] in Reference Fuels (liquid form)

SRMs 1 829, 1 837, 1 838, and 1 839 are for calibrating instruments and validating methods used to determine various

alcohols in gasoline. SRM 1829 is issued as a set of six sealed 20 mL ampules; SRMs 1837, 1838 and 1839 are each issued as a set of five sealed 20 mL ampules.

SRMs 2286 through 2297 were produced in response to the U.S. EPA Final Rule on Reformulated Gasoline

aimed at reducing the volatile organic compounds emitted from gasoline. They consist of varying quantities of

alcohol and ether (oxygenate) solutions in gasoline. SRMs 2286 through 2293 will be certified for constituent

oxygenate concentration and resultant oxygen concentration in gasoline. Each SRM unit is issued as a set of three

sealed 20 mL ampules—two ampules contain oxygenate and one ampule contains base reference gasoline.

SRMs 2294 through 2297 will be certified for total olefins, total aromatics, oxygenate, sulfur, and benzene. Each

SRM unit is issued as a set of two sealed 20 mL ampules. [NOTE: See Section 203 for Flash Point RMs.]

These SRMs and RMs are for calibrating or measuring organic contaminants found in a variety of environmental matrices.

They are listed in the table below and further described in tables on this and the following three pages. The first

three tables identify the SRMs for R\Hs, Pesticides, PCBs, methylmercury, and mercury, respectively. The SRMs

described therein are grouped according to application — calibration or natural matrix measurement. The calibration

SRMs are useful for validating the chromatographic separation step while the natural matrix SRMs, which are similar

to actual environmental samples, can be used to validate all the steps of an analytical procedure. The fourth table describes

SRMs and RMs certified for organic components in such matrices as oil, /jooctane, and methanol. NOTE: Due

to space limitations, only selected components are listed for most SRMs in the tables. Also, due to the types of components

certified, SRMs 1588a, 1941a, 1945, 1974a, and 2974, are listed in more than one table.

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

transition point, melting point and magnetic transition measurement RMs 8754, 8759, and 8760 for use with differential thermal analyzers, differential scanning calorimeters, and thermogravimetry apparatus.

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

SRM Program Sales Office.

204. Optical Properties

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

The optical SRMs for spectrophotometry are certified transfer standards that fall into three general categories

transmittance, wavelength, and stray radiant energy—each of which addresses a specific instrumental parameter of an 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 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 20 arc seconds or better, to reduce the optical deviation (relative

to SRM 930d) and improve performance in instruments where wavelength dispersion occurs after the light has

passed through the filter. SRM 930e consists of three 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 %,

20 %, and 30 %. The three filters are individually certified for transmittance at five 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 verify accurately 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 % to 50 %. A detailed discussion of this SRM and SRM 1930 is given in Special Publication 260-116. (See NOTE.)

SRM 931e: This SRM is for the verification of the absorbance scales of ultraviolet and visible absorption

spectrometers having narrow spectral bandpasses. SRM 931e consists of three sets of four 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 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 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. A detailed discussion of this SRM is given in Special

Publication 260-54.

SRM 1921: This SRM is for use in the calibration of the wavelength scale of spectrometers in the infrared (IR)

spectral region from 3.2 jxm to 18 \im (555 cm ' to 3125 cm"'). SRM 1921 consists of three cards made of a matte

finish polystyrene film, approximately 38 |xm thick with a 25-mm diameter clear aperture and centered 38 mm from

the bottom of a cardboard holder 5 cm X 1 1 cm X 2 mm in size. The certified wavelength values, corresponding

peak wavenumber values for thirteen absorption peak positions in the 3 [xm to 1 8 \x.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.

108
SRM 1930: This SRM complements SRM 930e for the verification of the transmittance and absorbance scales of

visible absorption spectrometers. SRM 1930 consists of three individual Schott NG-type glass filters in separate

metal cuvette-style holders and an empty filter holder. The nominal transmittances of the three filters are 1 %, 3 %,

and 50 %. The three filters are individually certified for transmittance at five 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 verify accurately 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 930e, a 6-point stepwise verification of the transmittance scale is possible over

the transmittance range from 1 % to 50 %. A detailed discussion of this SRM and SRM 930 is given in Special

Publication 260-1 16. (See NOTE.)

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 at the nominal transmittance of 30 %. SRM 2030a consists of one

glass filter in its holder and one 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 uncertainty estimation is described in Special Publication 260-116. (See NOTE.)

SRM 2031a: This SRM is for the verification of the transmittance and absorbance scales of ultraviolet and visible

absorption spectrometers. SRM 2031 consists of three individual non-fluorescent, fused silica filters in separate

metal cuvette-style holders and an empty filter holder. The nominal transmittances of the three filters are 10 %, 30 %, and 90 %. The quartz base plates of the 10 % and 30 % filters carry different thicknesses of

semi-transparent chromium metal that are optically contacted to quartz cover plates. The nominal 90 % filter is a

single clear quartz plate. The three filters are individually certified for transmittances at ten 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. CAUTION: Because the 10 % and 30 % chromium-coated filters attenuate incident radiation by reflection to a large extent, SRM 2031a may possibly generate interreflections

between optical surfaces in the sample compartment of some absorption spectrometers. Such interreflections may affect the accuracy of the transmittance measurement. Consequently, when contemplating the purchase of SRM 2031a,

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 rmi, 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 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% (m/v) holmium oxide in an aqueous solution of 10% (v/v) perchloric acid, is sealed in a nonfluorescent, 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. (See NOTE.)

NOTE: A recertification service for units of this SRM whose certification has expired, is available directly from the

NIST Analytical Chemistry Division. Contact the Division for details: Phone — (301) 975-41 15; Fax — (301)977-0587.

205. Natural Matrix Materials (powder form)

SRM 4350B—Columbia River Sediment

This material, provided in 85 g units, was collected from a river downstream from a nuclear reactor facility.

Concentrations of fission and activation products are elevated over typical world-wide levels. Plutonium-239/

plutonium-240 and americum-241 are very homogeneously distributed through the sample and are in acid-leachable

forms. Inhomogeneity is 3% or better for other radionuclides.

SRM 4351—Human Lung

This material, provided in 45 g units, contains radioactivity concentrations on the order of 10"'' Bq • g"'. It has been

freeze-dried, cryogenically ground, homogenized, and packed in a glass bottle under vacuum. There is significant

inhomogeneity in plutonium-239/ plutonium-240 which is unavoidable because plutonium was taken into the lungs in

particulate form. Assessments of accuracy of measurement techniques can be improved by averaging over several

samples.

SRM 4352—Human Liver

This material, provided in 45 g units, contains radioactivity concentrations on the order of 10" Bq • g"'. It has been

freeze-dried, cryogenically ground, homogenized, and packed in a glass bottle under vacuum. SRM 4353A—Rocky Flats Soil Number H In Prep

This material was collected at Rocky Flats, CO, but in a different location from its predecessor, SRM 4353. Transactinide concentrations are about an order of magnitude higher than typical world-wide levels and there is a potential

that =10% of these nuclides could be in refractory form. It is also possible that =15% of the uranium and thorium

nuclides present are in non-acid leachable form. The SRM is intended for use in validation of radiochemical

environmental studies methods.

SRM 4354—Freshwater Lake Sediment

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

50% organic by mass) 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 analytical methods, or as a generally

available calibrated "real" sample matrix in interlaboratory comparisons.

SRM 4355—Peruvian Soil

This material, provided in 75 g units, has nonmeasurable radioactivity concentrations for many fallout radionuclides

and can be used as a blank or for sensitive tests of radioanalytical procedures at low radioactivity concentrations for

other radionuclides. The results of a trace element study are given for 57 elements.

SRM 4356—Ashed Bone In Prep

uranium-238, plutonium-238, plutonium-239/plutonium-240, and curium-243/curium-244. The thorium-232 and

uranium-238 decay chains are not in equilibrium.

SRM 4357—Ocean Sediment

This material, provided in 80 g units, consists of a blend of sediments collected in the Chesapeake Bay and in the sea

off of the British Nuclear Fuels Sellafield facility in the United Kingdom. The SRM, which has been freeze-dried,

pulverized, homogenized, and radiation-sterilized, is intended for use in tests of low level radiochemical methods

for measurement of such fission products as strontium-90 and cesium- 137 and actinides such as thorium-232,

uranium-238, and plutonium-239/ plutonium-240.

SRM 4358—Ocean Shellfish In Prep

This material, provided in =300 g units, was prepared from oysters from the southeastern Pacific Ocean blended with

mussels from the White and Irish Seas. The SRM is intended for use in the validation of radiochemical ocean studies

methods on material which is both a food product and a bioaccumulator of radionuclides associated with ocean

nuclear waste dumping programs. The radionuclides determined include strontium-90, radium-226, thorium-228,

thorium-230, thorium-232, uranium-234, uranium-235, uranium-238, plutonium-238, and plutonium-239/plutonium240.

run. The materials were selected because of their differing 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 subcommittee of the Fundamental Research Committee. These materials were donated by

industry and are being distributed by the SRM 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.

I MSDS Index

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 1910.1200 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 NIST 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 U.S. Environmental Protection Agency

(EPA).

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

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

6. The SRM is a tobacco product, wood or wood product which is exempted by paragraph (b)(5)(ii) 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.
