ASTM D6906-12a

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

4.2 This test method is applicable for determination of the total coating weight and the titanium coating weight of a titanium-containing treatment.

1.1 This test method covers the use of wavelength dispersive X-ray fluorescence (WDXRF) techniques for determination of the coating weight of titanium treatments on metal substrates. These techniques are applicable for determination of the coating weight as titanium or total coating weight of a titanium 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.
