Description

This Standard Reference Material (SRM) is intended for the verification of Charpy machines equipped with an 8-mm striker, in accordance with the current ASTM Standard E23 and the current ISO Standard 148-2. Each SRM consists of a set of five specimens needed to perform one verification. NIST-2097 is used for in-house verification (self-verification). Material NIST-2097 is made from 4340 alloy steel. The bars are finished to length, stamped, heat-treated, and machined in SRM specimen lots of approximately 1200 to 2000 specimens. Each specimen has a lot number and an identification number (three or four digits).

National Institute of Standards and Technology

NIST provides over 1300 Standard Reference Materials® as well as articles and practice guides describing the development, analysis and use of SRMs.

NIST Standard Reference Materials are used by analytical laboratories in industry, academia and government in order to facilitate commerce and trade and to advance research and development. The SRMs are produced by the engineering laboratory, the material measurement laboratory, and the physical measurement laboratory at NIST. They are available for chemical composition, physical properties, and engineering materials.
