1.1 本试验方法包括使用波长色散X射线荧光（WDXRF）技术测定金属基材上钛处理的涂层重量。这些技术适用于测定各种金属基材上作为钛的涂层重量或含钛处理的总涂层重量，或两者兼有。 1.2 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.3 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 4.1 本试验方法中描述的程序旨在提供一种方法，通过该方法可以确定金属基材上钛处理的涂层重量。 4.2 本试验方法适用于测定含钛处理的总涂层重量和钛涂层重量。

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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 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.
