Abstract

This paper documents major changes in the production of Electrodeposited Coating Thickness Standard Reference Materials. These standards consist of pre-configured sets of electrodeposited copper on steel substrate coupons with thicknesses ranging from 2.5 m to 2000 m. The coatings are overplated with chromium and the total coating thickness is certified. These standards are primarily intended for use in calibrating coating thickness measurement instruments based on magnetic induction principles. These instruments are used by the coating industry for the nondestructive measurement of nonmagnetic coatings over magnetic substrates. Technical aspects of the manufacture and certification process of these standards are covered. Uncertainties for these certifications were improved to 2 % maximum for mean thickness over previous releases.
