Description
This Standard Reference Material (SRM®) is a transfer standard intended primarily for use in the calibration and verification of the performance of Rockwell hardness equipment using the Rockwell Hardness 30N scale (HR30N). A unit of NIST-2821 is a steel test block, nominally 64 mm in diameter and 15 mm thick, having a polished test surface described by a micro-engraved circle 52 mm in diameter. Each SRM® unit bears a unique serial number on the edge of the block. /// Sample value(s) - please ask for current certificate.

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.
