Dear Colleague:

I hope that you find this new Standard Reference Materials Catalog to be the best edition

we have issued. We have tried to make it user oriented to help you find the materials you

need both quickly and easily. We think, and hope you will agree, that the revised alphabetical

index is a major improvement over earlier editions.

Because finding the right SRM out of almost 1,000 can be difficult, I would like to suggest

the following approach:

1 . Start with the Contents,

2. Flip though the Catalog to see its organization,

3. Browse through the Alphabetical Index.

Most of the materials are classified by matrix (such as steel) or by use (such as clinical

chemistry). However, with such diverse offerings, the categories are not mutually exclusive,

and you may find some materials of interest to you in any part of the Catalog.

The 1984-1985 Catalog went to about 45,000 people. At least 60,000 copies of this one will be distributed. I think this indicates an increasing interest in quality measurements. We are happy to be part of this tradition and welcome you to the growing family of SRM users.

Stanley D. Rasberry

P.S. Please do not hesitate to call us if you have any questions about the SRM's

described, their availability, or if you cannot find what you need. We would be

happy to have your suggestions for improved service and new SRM's (see Guide

for Requesting the Development of New SRM's).

Sincerely,
NBS Special Publication 260

Standard Reference Materials 1986-87 Catalog

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

Bureau of Standards (NBS), 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.

Program Information

The National Bureau of Standards (NBS) offers for sale over 900 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."

NBS Standard Reference Materials (SRM's): Certified reference materials issued by NBS. 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 NBS 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.

NBS 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, NBS. 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 principle 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 NBS), 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, NBS 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.

Reference Materials (center).

SRM Catalog

New catalogs of NBS Standard Reference Materials are published approximately every two 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 six 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 an alphabetical index that lists categories

of materials, elements, and names of materials. The second is a numerical index that lists the numbers,

names, and certificate dates of the materials in the catalog.

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 Bureau of Standards 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.

4
NBS currently has over 900 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 NBS would provide continued availability of a well-characterized material

important to science, industry, or government.

NBS 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 Bureau'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, NBS 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 NBS welcomes all requests for developing new SRM's, both NBS 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

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

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

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 Bureau of Standards 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 cancelled. Customers are notified when an order is cancelled; 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.

Terms

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.

Late Charges

Unless otherwise notified, payment is due within 30 days of shipment of the order to the customer. U.S.

Treasury regulations require that late charges be assessed for each 30-day period, or portion thereof, that

the payment is overdue.

Proforma Invoice (Price Quotation)

Proforma service will be provided only to those requiring such service.

Domestic Shipments

Shipments of material (except for certain restricted categories and refrigerated items) intended for the

United States and Canada are normally shipped prepaid, providing the parcel does not exceed the weight

limitations prescribed by postal laws and regulations. Refrigerated items are shipped collect via air express.

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

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" 1 " and has been given the special name becquerel (Bq). The relationship

between the curie and the bequerel is:

1 Ci = 3.7 X 10 10 Bq.

Many SRM's are measured and certified in terms of emission rate. In this catalog, as

-1

, y3~s _1

, yS +

s _1

, Kxs~\ and ys" 1 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 Bureau of Standards,

Gaithersburg, MD 20899; or telephone (301) 921-2665.

In addition, chemically stable solutions of most radionuclides may be submitted to NBS for

calibration as described in National Bureau of Standards Calibration Services User Guide, NBS Special

Publication 250 (1986, ed.). Requests for these test should be submitted, with full source information for

approval of suitability to the Radioactivity Group.

Environmental Natural Matrix Materials for Traceability Tests

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. 239/ 240 Pu and 241 Am are very

homogenously distributed through the sample and are in soluble chemical forms. Inhomogeneity does not

exceed 3 percent for other radionuclides.

SRM 4351—Human Lung

This material contains radioactivity concentrations on the order of 10" 4 Bq g" 1

. It has been freeze-dried,

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

inhomogeneity in 239/ 240 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" 4 Bq g" 1

. It has been freeze-dried,

cryogenically ground, homogenized, and packed in a glass bottle under vacuum.

107
SRM 4353—Rocky Flats Soil Number 1 This material was collected within 13 centimeters of the soil surface at Rocky Flats, Co. 239 Pu and 241 Am

concentrations are about an order of magnitude higher than typical world-wide levels. Approximately 10

percent of the plutonium is in a refractory chemical state. The material also contains "hot" particles and a

statistical method is provided for dealing with these. Inhomogeneities, excluding hot particles, do not exceed

3 percent.

SRM 4355—Peruvian Soil

This material, which has been the subject of a trace-element study, 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 the

trace-element study are given for 57 elements.

RM 45B—River Sediment

This material contains radioactivity concentrations of roughly an order of magnitude greater than SRM

4350B. The values, however, are uncertified although the inhomogeneity does not exceed 3 percent for all radionuclides. This material can be used for routine checking for reproducibility of results after tests have

been performed with SRM 4350B.

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.
