Description
Standard Reference Material (SRM®) 2073a is a sinusoidal profile roughness specimen certified for roughness average, Ra, and surface spatial wavelength, D. The SRM is intended for use as a standard for the calibration of stylus instruments that are used to measure surface roughness. A unit of nist-2073a is a steel block of nominal Knoop hardness (HK) 500 which has been coated by the electroless nickel deposition process. A sinusoidal roughness profile was machined onto the top surface of the specimen in a facing operation, using a single-point diamond tool on a numerically controlled lathe. /// Sample value(s) - please ask for current certificate.
