Materials
Standard Reference Materials are well-characterized materials disseminated by the National Bureau of Standards to be used to calibrate and

evaluate measuring instruments, methods, and systems or to produce

scientific data that can be referred readily to a common base. The materials

are certified for chemical comj}osition or for a particular physical or

chemical property. They are used on-site in science and industry to

calibrate instruments and methods used in j)roduction and quality control

oj raw materials, chemicals, metals, ceramics, fuels, and radioactive

nuclides in manufacturing processes and in research.

ORDERING PROCEDURE

Orders should be addressed to the Office of Standard Reference Materials, Room B311,

Chemistry Building, National Bureau of Standards, Washington, DC 20234 (Telephone 301-

921-2045). Orders should give the number of units, catalog number and name of the standard

requested. For example: 1 unit of SRM llh, Basic-Open Hearth Steel, 0.2 percent C. These

materials are distributed only in the units listed. Acceptance of an order does not imply ac- ceptance of any provision set forth in the order contrary to the policy, or regulations of the

National Bureau of Standards or the US Government.

Prices listed herein are subject to change without notice. Prices in effect at time of shipment will be billed to the purchaser. No discounts are given on NBS Standard Reference

Materials. Payments not accompanying purchase orders are expected within 30 days after

receipt of invoices.

Payments of foreign orders may be made by any of the following:

(a) UNESCO coupons,

(b) banker's draft against U.S.A. bank,

(c) bank to bank transfer to U.S.A. bank,

(d) letter of credit* on a U.S.A. bank, or

(e) by International Money Order.

requiring such service.

^Letters of Credit may be used as advance payment for SRM's; they will be accepted from

banks in the United States only. Only the documents listed below will be furnished:

(1) Six Commercial Invoices,

(2) Packing List,

(3) Certificate of Origin, and

(4) Airway Bill (only if material is shipped Collect; no receipt can be furnished for material shipped by International Air Parcel Post).

DOMESTIC SHIPMENTS of material (except for restricted categories) for the United

States and Canada are shipped prepaid if the parcel does not exceed weight limitations. For

restricted categories and where the purchaser requests a special mode of shipment, the shipment will be sent collect; the Bureau does not prepay and add these shipping charges to the

billing invoice.

FOREIGN SHIPMENTS of materials are shipped by prepaid International Air Parcel Post,

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

requested by a customer must be paid for by the customer. Shipments excluded from International Air Parcel Post are shipped Air Freight Collect. Certain materials 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 express collect to the US firm designated as agent.

NOTE: All shipments are made in compliance with existing regulations pertaining to the

material at time of shipment.

SRM DESCRIPTIONS BY CATEGORY

The categories listed are in the same order as they appear in the 1975-76 edition of NBS SP 260,

Catalog of NBS Standard Reference Materials. The new and renewal SRM's issued since the 1975-76

edition of SP 260 are listed numerically within the appropriate category.

To list new and renewal radioactivity SRM's is impractical because of the half-life of many of these

materials. A special brochure that describes these materials is available from the Office of Standard

Reference Materials, Room B311, Chemistry Building, Washington, DC 20234, (301) 921-2045. This brochure is supplied with its own price list, which is regularly revised to reflect currently available radioactivity SRM's.
