Dear Colleague:

Welcome to the very first catalog of Standard Reference Materials (SRM's) to be issued by the National Institute of Standards and Technology. Of course, the materials listed herein are an

extension of 84 years of service to the U.S. technical community provided by the National Bureau of

Standards since 1906. Our new name is indicative of the effort we are making to extend the tradition of SRM service into new fields and into a new era of service to technology.

You will find over two hundred changes in SRM availability listed in this catalog —new additions,

renewals, and revised certificates. Please carefully review the sections which relate to your work to see the new (and previously issued) SRM's that are available. If we can help you with regard to any

listing please give us a call.

Many of you have told us, at SRM exhibits, or by letter, that you are happy that SRM's continue to be available through the new NIST organization. In fact, we are seeing some modest growth in our

ability to supply the materials that you need. If you have a requirement that we do not currently

meet please let us know about it. In the front pages of this catalog you will find a section entitled Guide for Requesting Development of Standard Reference Materials. You can register your need

with us with just a few minutes of effort. Then, as funding permits, we can try to be responsive to your needs.

Thank you for your continued interest in Standard Reference Materials from NIST. It is our privilege

to provide them to you and thereby enhance the quality of measurements and analyses made

throughout the technical community.

Sincerely,

William P. Reed

Standard Reference Materials 1990-91 Catalog

This catalog describes the Standard Reference Materials (SRM's) currently available from the National

Institute of Standards and Technology (NIST), lists those in preparation, and provides ordering information.

The descriptions provide nominal values for these SRM's. Certified values are provided in the certificates that accompany each SRM. Price Lists for SRM's are issued as separate supplements to this catalog and

include new SRM's as they are issued. Key Words: analysis, calibration, characterization, composition, concentration, materials,

measurement, property, quality assurance, quality control, reference materials, Standard Reference

Materials, standardization.

Lookfor us at the next meeting you attend! Our new exhibit booth, attended by representatives of our sales and technical staff, is scheduled to be at about a dozen professional meetings and expositions each year.

The Engineering Mechanics Building is now the home of the Standard Reference Materials Program. We lookfommd to continued and

improved service to the technical community in our new offices and materials preparation and

packaging facilities.
Program Information

The National Institute of Standards and Technology (NIST) offers for sale over 1,000 different materials

through its Office of Standard Reference Materials. These materials are primarily Standard Reference

Materials (SRM's) certified for their chemical composition, chemical property, or physical property, but

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 30-1981 (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 (SRM's): Certified reference materials issued by NIST. These are wellcharacterized materials produced in quantity to improve measurement science. SRM's 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 of three routes of measurement:

(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. These measurement routes are described in "The Role of Standard Reference Materials in Measurement Systems," NBS Monograph 148, 54 pages (Jan 1975).

Reference Materials (RM's) listed in this catalog are sold by, but not certified by, NIST. They meet the ISO

definition for RM's, and many meet the definition for CRM's. The documentation issued with these

materials is either a: (1) "Report of Investigation," the sole authority of which is the author of the report. RM's are intended to further scientific or technical research on that particular material. The principal consideration in issuing an RM 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.

Stan Rasberry, the new Acting Director ofMeasurement Services,

displays one of the many SRM's developed in the program of the Office ofStandard Reference Materials (OSRM). The enthusiasm and

decisiveness Stan exercised while Chief of OSRM will continue to be an

asset to the SRM program as well as to the additional programs to which he will now provide leadership —Standard Reference Data,

Physical Measurement Services and the National Voluntary Laboratory

Accreditation Programs.

SRM Catalog

New catalogs of NIST Standard Reference Materials are published approximately every 2 years, listing

materials available and materials in preparation, and deleting discontinued materials. Catalog supplements

(Price Lists) are issued simultaneously with new catalogs and approximately every 6 months to keep the

catalog current between editions. These supplements list current prices, and reflect any changes in material

availability—listing new and renewed materials and dropping discontinued ones. The numerical values given in this catalog to describe the materials' properties are NOMINAL

values only and are to be used only as guides in selecting SRM's. They are NOT TO BE USED in place of

the values given on the certificate issued with the materials.

Two indices are provided for user convenience. The first is a numerical index that lists the numbers,

names, and certificate dates of the materials in the catalog. The second is an alphabetical index that lists categories of materials, elements, and names of materials.

Preparation and Availability of Standard Reference Materials

New and renewal SRM's are being prepared continually. These SRM's are included in the next edition of

the catalog and its supplements. Prospective users that have requested that their names be added to the

SRM mail list are notified as these new items become available. To have your name placed on this mail list, please write to the address given below.

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

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 substitutes (if any) 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 SRM's are not identical to the preceeding lot; however, they meet the same specifications

and can be used for the same purpose. For example, the first 0. 1 percent carbon Bessemer steel was

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

The current SRM 8j, Bessemer Steel (Simulated), 0.1% C, 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 Standard Reference Materials

The National Institute of Standards and Technology has the function to develop, produce, and distribute Standard Reference Materials (SRM's) that provide a basis for comparison of measurements on materials,

and that aid in the control of production processes. To perform this function, the Office of Standard

Reference Materials evaluates the requirements of science, industry, and government for carefully

characterized reference materials, and directs their production and distribution. NIST currently has over 1,000 SRM's available, about 100 new ones in preparation, and requests for the production of many others. To be an 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.

4. Its production by NIST would provide 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 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 SRM's greatly exceed

the Institute's capacity to produce and certify such materials. Consequently, requests for new SRM's of

limited use, or for which the need is not very great, are deferred in favor of requests that clearly show a

critical need. To determine which requests receive top priority, NIST needs and uses information supplied

by industry and such interested organizations as the American National Standards Institute, American

Nuclear Society, American Petroleum Institute, American Society for Testing and Materials, etc. Accordingly, while NIST welcomes all requests for developing new SRM's, both NIST and industry

would be helped if such requests provide information that permit objective assessment of the urgency and

importance of the proposed new reference materials.

Requests for the development of new Standard Reference Materials should provide information such as

listed below.

1. Short title of the proposed SRM.

2. Purpose for which the SRM would be used.

3. Reasons why the SRM is needed.

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

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

5. An estimate of the probable present and future (6-10 year) demand for such an SRM in your

operations and elsewhere. (National and international estimates are useful.)

6. Whether such an SRM, or a similar one, could be produced or obtained from a source other than

NIST; and if so, justify its preparation by NIST.

7. Miscellaneous 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 committees, and others.

All such requests should be addressed to: Office of Standard Reference Materials

Fax number: (301) 948-3730

Telex: TRT197674NIST UT

All orders should give the number of units, catalog number, and name of the material requested. For

example: "1 each, SRM 79a, Fluorspar (Customs Grade)." The materials described in this catalog are sold

only in the units listed or multiples thereof. Acceptance of an order does not imply acceptance of any provisions set forth in the order contrary

to the policy, practice, or regulations of the National Institute of Standards and Technology or the U.S.

Government.

In general, orders received for "out-of-stock" material will be filled with the renewal material, if available; otherwise they will be canceled. Customers are notified when an order is canceled; and their names are placed on a notification list. This list is used when a renewal material is issued to notify customers

of the price and availability of the item. Customers so notified are requested to submit a new order if they

still want the item.

For some individually certified SRM's, production lots are small and may entail frequent stock

outages. In these cases, the notification list is used to fill orders on a "first come, first served" basis. NOTE:

For such SRM's, customers are notified that the SRM is again available and are requested to confirm their original purchase orders.

Lee Best, Manager of Sales and Marketing, has developed an excellent sales and

marketing staff through the thoroughness and initiative of her leadership. We look forward to meeting many ofyou at one of

the many exhibits Lee has scheduledfor the

endurance in every responsibility she receives, serves as SRM assistant, performing many tasks in sales and

marketing, including foreign sales.

Prices quoted are in U.S. dollars ($), and are published in the catalog supplements (price lists). When price

lists are issued, they are sent to persons or organizations on the SRM mail list. These prices are subject to change without notice and orders will be billed for the prices in effect at the time of shipment. No discounts

are given on purchases of SRM's or RM's.

Remittances of the purchase price need not accompany the purchase order. Payment of invoices is expected within 30 days of the receipt of the invoice. Payment on foreign orders may be made by any of the

following:

a. Banker's draft against U.S.A. bank,

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

c. Cash against documents,

d. Sight draft,

e. International money order, or

f. UNESCO coupons.

Letters of credit: If a letter of credit or any method of payment other than those listed above is to be used,

the services of an agent in the United States must be secured to act in your behalf. Your agent would

purchase the material and our invoice would indicate that the agent is the purchaser. The material would be

shipped to your agent, who would tranship in accordance with your instructions. NOTE: A customer identification number; i.e., social security number (EIN) for consumer customers; tax

identification number (TIN) for commercial customers; or agency location code (ALC) for government

customers, is required with each order.

Phyllis Wagner, an SRM assistant, provides consistency and dependability to the delivery of many SRM's through her expertise in regulations andproceduresfor the shipment ofhazardous materials.

cooperativeness to the task of updating information for the preparation and publication of the new 1990-91 SRM

Catalog.

Foreign Shipments

The regulations of various nations covering the importation of SRM's differ widely; any attempt to list all possible variations would be impractical. Therefore, where shipping practices outlined below do not apply,

purchasers will be informed of the best method of shipment for their countries.

Most foreign orders will be shipped by prepaid International Air Parcel Post. Exceptions are those

items in restricted categories, those items requiring refrigeration, and shipments exceeding parcel post

weight limits. These exceptions will be shipped FOB Gaithersburg, MD, unless an agent (shipping or brokerage firm) located in the United States is used. When an agent is required, the purchaser will be

notified and will be requested to obtain the services of one and inform us of the agent's name and address. In such cases, the material will be packed for overseas shipment and will be forwarded to the agent FOB

Gaithersburg, MD.

Documentation

The documents we furnish are:

a. Two commercial invoices,

b. Two sight drafts,

c. Two packing slips, and

d. An air waybill for air shipments.

(All documents are printed in English.)

If documents other than those listed above are required, the services of an agent in the United States will be

needed to purchase and ship the material.

NOTE: Orders and inquiries submitted in English will be processed more rapidly than those requiring

translation. 9

SRM 1866, Bulk Asbestos-Common, is a set of the three common bulk mine-grade asbestos materials and one synthetic glass fiber sample. There are 4-5 grams of each sample in the set of materials. The three

asbestos types are Chrysotile, Grunerite (Amosite), and Riebeckite (Crocidolite). The optical properties of

each of these materials observed by polarized light microscopy have been characterized so that these

samples may serve as primary calibration standards for the identification of asbestos types in building

material. SRM 1867, Bulk Asbestos-Uncommon, will contain three materials: Anthophylite, Actinolite, and

Tremolite and will be used in the same manner and for the same purpose as SRM 1866.

RADIOACTIVITY

These SRM's are shipped express or air freight (shipping charges collect). The amount of a radionuclide in an SRM, at a specified time, is stated as (1) the number of atoms (or the mass, for radium SRM's), (2) the

activity, or "decays per second," or (3) the emission rate of a particular radiation, depending on the method

of calibration or the intended use. For solution SRM's, the quantity is usually specified per gram of liquid.

The active portion of gamma-ray "point-source" standards is usually restricted to the central few millimeters

of a low-mass, low-Z support to minimize scattering. Alpha-particle-emitting radionuclides are deposited or

plated on metal backings.

The unit for activity has traditionally been the curie (Ci), but simpler relations between activity,

emission rate, and counting rate result if the current SI (International System of Units) unit " 1 per second"

is used. This is symbolized as "s~ ^" and has been given the special name becquerel (Bq). The relationship

between the curie and the becquerel is:

1 Ci = 3.7 X lO^" Bq.

Many SRM's are measured and certified in terms of emission rate. In this catalog, as~\ P~s~\ fi*s~\

Kxs~\ and ys"^ are used for the emission rates of alpha particles, negatrons, positrons, K x rays, and gamma

rays, respectively.

The SRM's without an asterisk (*) may be ordered singly, without a license, under the general

licensing provisions of the Atomic Energy Act of 1954. Those marked by an asterisk are available only

under the special licensing provisions of the Atomic Energy Act of 1954. NOTE: Certain radionuclides are not economical to maintain in stock because of short half lives or low demand. When sufficient demand exists, based on letters of inquiry, these materials are prepared and

those who have expressed interest are notified of their availability. If you need any radionuclide not listed, write the Radioactivity Group, Room C114 Radiation Physics Building, National Institute of Standards and

Technology, Gaithersburg, MD 20899; or telephone (301) 975-5531. In addition, chemically stable solutions of most radionuclides may be submitted to NIST for calibration as described in Calibration Services Users Guide, NIST Special Publication 250 (1986-88/

Revised ed.). Requests for such tests should be submitted, with full source information, for approval of

suitability to the Radioactivity Group.

Bert Coursey and Bill McLaughlin of the Ionizing Radiation Division discuss the preparation and

measurement ofa radioactivity sample.

Environmental Natural Matrix Materials for Quality Assurance Testing

SRM 4350B—Columbia River Sediment

This material was collected from a river downstream from a nuclear reactor facility. Concentrations of

fission and activation products are elevated over typical world-wide levels. ^'"TPu and ^'•'Am are very

homogeneously distributed through the sample and are in acid-leachable forms. Inhomogeneity is 3 percent or better for other radionuclides.

SRM 4351—Human Lung

This material 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 2*°Pu which is unavoidable because plutonium was taken into the lungs in particulate

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

samples.

SRM 4352—Human Liver

This material 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 4353—Rocky Flats Soil Number 1 This material was collected within 13 centimeters of the soil surface at Rocky Flats, CO. 239/24opy ^j^^j 24o Am concentrations are about an order of magnitude higher than typical world-wide levels. Approximately

10 percent 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 percent or better. SRM 4354—Freshwater Lake Sediment

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

(approximately 50 percent 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

analytical methods, or as a generally available calibrated "real" sample matrix in interlaboratory

comparisons.

SRM 4355—Peruvian Soil

This material has non-measurable 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.

Engineering Materials

standard Rubbers and Rubber-Compounding Materials

These SRM's 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, and vulcanizing them in accordance with ASTM Designation D-15 and determining the stress- strain properties of the resulting vulcanizates. Certificates are issued for the rubbers because the properties

of different lots are not the same. Replacement lots of rubber-compounding SRM's impart essentially the same characteristics to rubber vulcanizates so that Certificates are not issued for these SRM's.
