本文件规定了一种测量金属涂层厚度的方法，首先在涂层表面与其基材表面之间形成台阶，然后使用轮廓记录仪器测量台阶高度。它涵盖了仪器特性和适用于轮廓测量方法这一特定应用的程序。 该方法适用于测量平坦表面上0.01μm至1000μm的金属涂层厚度，如果采取了适当的预防措施，则适用于圆柱表面上的金属涂层厚度。它非常适合测量微小厚度，但对于小于0.01μm的厚度，表面平整度和表面光滑度非常关键，因此，该方法不适用于低至电子触针仪器通常测量的最低水平。 该方法适用于制备涂层厚度参考标准时测量涂层厚度。

This document specifies a method for the measurement of metal coating thickness by first forming a step between the surface of the coating and the surface of its substrate and then measuring the step height using a profile recording instrument. It covers the instrumentation characteristics and the procedure appropriate to this specific application of profilometric methods. The method is applicable to the measurement of thicknesses of metal coatings from 0,01？μm to 1？000？μm on flat surfaces and, if appropriate precautions are taken, on cylindrical surfaces. It is highly suitable for the measurement of minute thicknesses but, for thicknesses of less than 0,01？μm, surface flatness and surface smoothness are very critical and, accordingly, the method is not suitable for use down to the lowest level of measurement usual for electronic stylus instruments. The method is suitable for measuring coating thicknesses when preparing coating thickness reference standards.
