本文件规定了使用相敏涡流仪无损测量金属和非金属基材上非磁性金属涂层厚度的方法，例如: a） 钢上的锌、镉、铜、锡或铬； b） 复合材料上的铜或银。 与ISO 2360中规定的振幅敏感涡流法相比，相位敏感法可以在没有厚度误差的情况下应用于更小的表面积和更强的表面曲率，并且受基材磁性的影响较小。然而，相敏法更受涂层材料电性能的影响。 在本文件中，术语“涂层”用于油漆和清漆、电镀涂层、搪瓷涂层、塑料涂层、覆层和粉末涂层等材料。 交叉引用:ISO/IEC指南98-3ISO 2064ISO 4618ISO 5725-1:1994ISO/IEC指南99:2007ISO 2178ISO 5725-2ISO 2360ISO/TR 22971购买本文件时提供的所有现行修订版均包含在购买本文件中。

This document specifies a method for using phase-sensitive eddy-current instruments for non-destructive measurements of the thickness of non-magnetic metallic coatings on metallic and non-metallic basis materials such as: a) zinc, cadmium, copper, tin or chromium on steel; b) copper or silver on composite materials. The phase-sensitive method can be applied without thickness errors to smaller surface areas and to stronger surface curvatures than the amplitude-sensitive eddy-current method specified in ISO 2360, and is less affected by the magnetic properties of the basis material. However, the phase-sensitive method is more affected by the electrical properties of the coating materials. In this document, the term "coating" is used for materials such as, for example, paints and varnishes, electroplated coatings, enamel coatings, plastic coatings, claddings and powder coatings.Cross References:ISO/IEC Guide 98-3ISO 2064ISO 4618ISO 5725-1:1994ISO/IEC Guide 99:2007ISO 2178ISO 5725-2ISO 2360ISO/TR 22971All current amendments available at time of purchase are included with the purchase of this document.
