4.1 The thickness of the coating is an important factor in the performance of the coating in use and is usually specified in the coating specification.

4.2 This method is applicable to acceptance testing.

ASTM B487-2013 通过截面显微镜测量金属和氧化物涂层厚度的标准测试方法

步 1: 范围

1.1 The test method includes the use of an optical microscope to measure the local thickness of the metal and oxide coating by examining the cross section under a microscope.

1.2 Under good conditions, the method can provide an absolute measurement accuracy of 0.8μm when using an optical microscope. This will determine the suitability of the method for measuring the thickness of the thin coating.

1.3 本标准并非旨在解决所有安全问题, 如果有的话, 与其使用相关. 本标准的使用者有责任建立适当的安全和健康实践，并在使用前确定监管限制的适用性. (This applies in particular to the chemicals cited in Table X2.1.)
