Description
This Standard Reference Material (SRM®) is intended primarily for use in calibrating Knoop-type microhardness testers and is certified for mean Knoop hardness values at loads of 0.245 N, 0.490 N, and 0.980 N (0.025 kgf, 0.050 kgf, and 0.100 kgf, respectively). A unit of NIST-1895 consists of a square test block of electrodeposited bright nickel on an AISI 1010 steel substrate. The test block measures 1.35 cm on each side, is approximately 1 mm thick, and is mounted in a thermosetting epoxy. Five indentations were made on the SRM??s polished surface for each load. Knoop hardness values are reported as Knoop hardness numbers (HK) in units kgf/mm2 and in SI units of gigapascals (GPa). Each SRM was individually 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.
