Description
This Standard Reference Material (SRM®) is intended primarily for use in calibrating Vickers-type microhardness testers and is certified for mean Vickers hardness valuers (HV) at a load of 9,81 N (0.300 kgf). NIST-1909 consists of a 1,35 cm square test block of electrodepisited bright nickel, approximately 750 µm thick, on an AISI 1010 steel substrate, mounted in an thermosetting epoxy. Hardness value is reported in gigapascal (GPa) and kgf/mm². The SRM was indiviually measured and bears a serial number imprinted on the side of the epoxy mount. /// 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.
