1.1 This test method covers the use of energy dispersive X-ray uorescence (EDXRF) spectrometry for determining the coating weight (mass) of titanium (Ti) per unit area on metal substrates. 1.2 Coating treatments can also be expressed in units of linear thickness provided that the density of the coating is known, or provided that a calibration curve has been established for thickness determination using standards with treatment matching this of test specimens to be analyzed. For simplicity, the method will subsequently refer to the determination expressed as coating weight. 1.3 EDXRF is applicable for the determination of the coating weight as titanium or total coating weight of a titanium containing treatment, or both, on a variety of metal substrates. 1.4 The maximum measurable coating weight for a given coating is that weight beyond which the intensity of the characteristic X-ray radiation from the coating is no longer sensitive to small changes in weight.
