说明

一般說明

This Standard Reference Material (SRM) is intended for use as a primary standard 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 SRM 1893 consists of a square test block of electrodeposited bright copper on an AISI 1010 steel substrate. The test block measures 1.35 cm on each side, is approximately 1.5 mm thick, and is mounted in a thermosetting epoxy. For more information, please refer to the SDS and COA.
