Price and Availability List
IMPORTANT NOTICE TO PURCHASERS AND USERS OF

NBS STANDARD REFERENCE MATERIALS

The Office of Standard Reference Materials no longer issues the Quarterly Insert Sheets to

update the current issue of the SRM Catalog. Instead a Standard Reference Material Availability and

Price List is issued semiannually. The format has been changed to improve readability and the List is organized as follows:

Section I - A list of all classes of materials currently available arranged by Standard Reference

Material (SRM), Research Material (RM), and General Material (GM) numbers, together

with type, unit of issue, and current price.

Section Ila — A list of all classes of materials that have been issued since the Catalog (July

1970) was published, arranged by SRM, RM, and GM numbers together with catalog

category.

Section lib — A short description, arranged by catalog category, of all SRM's issued since the

Catalog (July 1970) was published and therefore not contained therein. For ease of

reproduction, tables have been condensed and are, in general, not in the same format used

in the catalog. (Please note that the values shown are nominal values. The actual values

certified are given on the Certificate which accompanies the material.) The unit of issue

and price are given after the description of each SRM.

Section llla — A list, arranged by SRM numbers, of recently issued certificates (final or revised

versions).

Section Illb — A list, arranged by SRM, RM, and GM numbers, of all items that have gone out

of stock since the effective date of the current catalog. A remarks column gives information concerning alternate SRM's, when the renewal SRM is expected, and similar

information.

Section IV — Changes in policy, ordering, shipping, and information of a general nature.

Catalogs are printed without prices to eliminate the need for an annual catalog. New issues of

Standard Reference Materials Availability and Price List are mailed automatically to all current

customers and those who have completed our Technical Point of Contact Questionnaire.

Category 6.0. Research Materials

A new class of materials is now being issued to meet the needs of scientists

engaged in materials research. Designated Research Materials (RM's), these are

in addition to and distinct from the Standard Reference Materials issued by

NBS. The distinctions between Research Materials and Standard Reference

Materials are in the information supplied with them and purpose for which

they are used. Unhke SRM's, the RM's are not issued with Certificates of

Analysis; rather they are accompanied by a "Report of Investigation," the sole

authority of which is the author of the report. A Research Material is intended

primarily to further scientific or technical research on that particular material.

One of the principal considerations in issuing an RM is to provide homogeneous

material so that an investigator in one laboratory can be assured that the

material he has is the same as that being investigated in a different laboratory.

22
Ultra-purity aluminum single crystal cubes (1 cm on a side) are intended for use

in studies of a variety of solid state phenomena for which both extreme purity

and knowledge of crystallographic orientation are required; e.g., in studies of

electron spin resonance, De Haas-Van Alphen effect, cyclotron resonance, etc.,

and in a variety of studies relating to the Fermi surface and the transport

properties of aluminum. RM-IC costs $90 per unit.

Ultra-purity aluminum polycrystalline rods (4.2 mm in diameter and 25.4 mm

long) are intended for use in research on the mechanical and physical properties

of extremely pure aluminum: for example, in the determination of resistivity as a function of strain at cryogenic temperatures to facilitate the design of cryogenic magnets or superconductor stabilizing elements. RM-IR costs $50 per

unit.

Category 7.0. General Materials

Another new class of materials now being distributed by NBS to meet industry

needs is General Materials (GM's). These materials have been standardized

either by some Government agency other than NBS, or by some standardsmaking body such as the American Society for Testing and Materials (ASTM),

the American National Standards Institute (ANSI), and the Organization for

International Standardization (ISO). For this class of materials, NBS acts only

as a distribution point and does not participate in the standardization of these

materials.

standards were produced and certified by The Welding Institute in Cambridge,

England. GM-1 is a set of 15 cylinders, 5 each of HI, H2, and H3, containing

nominally 0.05, 0.10, and 0.20 ml hydrogen, respectively. The cylinders are 6.35 mm in diameter and about 30 mm long, weighing approximately 6 grams.

GM-1 costs $86 per set.

Hydrogen in Steel Standards are distributed in the United States by NBS. The

standards were produced and certified by The Welding Institute in Cambridge,

England. GM-2 is a set of 15 cylinders, 5 each of H4, H5, and H6, containing

nominally 0.20, 0.60, and 1.10 ml hydrogen, respectively. The cylinders are 12.7 mm in diameter and about 30 mm long, weighing approximately 22

grams. GM-2 costs $86 per set.

Attapulgus clay is distributed by NBS on request of the ASTM Committee

D-2007. It is an adsorbant type clay, 30 to 60 mesh, having adsorptive characteristics as specified by ASTM D-2007. (This material is temporarily out of

stock.

CERTIFICATES

In general, Provisional Certificates are issued for Standard Reference Materials before all of the

values have been certified, but after a sufficient number of values are certified so that the material is a valuable standard for the intended purpose. As additional values are certified, the Provisional

Certificate may be revised and when and if all of the values are certified, the final Certificate is issued.

New or revised Certificates have been issued for the SRM's listed below. SRM purchasers

whose Certificates show an earlier date may obtain copies of these Certificates from: Office of

Standard Reference Materials, Room B314, Chemistry Building, National Bureau of Standards,

Shipments of material (except for certain restricted categories, e.g., hydrocarbons, organic

sulfur compounds, special nuclear materials, compressed gases and radioactive standards) intended

for the United States, Mexico, and Canada are normally shipped prepaid air parcel post (providing

that the parcel does not exceed the weight limits as prescribed by Postal Laws and Regulations)

unless the purchaser requests a different mode of shipment, in which case the shipment will be sent

collect. It is impractical for the Bureau to prepay shipping charges and add this cost to the billing

invoice. Hydrocarbons, organic sulfur compounds, compressed gases, rubber compounding materials, radioactive standards and similar materials are shipped express collect.

FOREIGN SHIPMENTS

Both prepaid and non-prepaid orders will be shipped by prepaid International Air Parcel Post,

subject to size, weight, and category of material limitations. Any other mode of shipment requested

by customer must be paid for by the customer. Shipments excluded from International Air Parcel

Post for any reason, must be handled through an agent (shipping or brokerage firm) located in the

U.S. as designated by the purchaser. These parcels will be packed for overseas shipment and

forwarded via express collect to the U.S. firm designated as agent. NOTE: Nuclear SRM's will not

be shipped through an agent, they will be shipped direct.
