The procedure described in this practice is designed to provide a method by which the coating weight of chromium treatments on metal substrates may be determined.

This procedure is applicable for determination of the total coating weight and the chromium coating weight of a chromium-containing treatment.

1. Scope

1.1 This practice covers the use of X-ray fluorescence (XRF) techniques for determination of the coating weight of chromium treatments on metal substrates. These techniques are applicable for determination of the coating weight as chromium or total coating weight of a chromium-containing treatment, or both, on a variety of metal substrates.

1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
