ISO 2178:2016规定了磁化基底金属上非磁化涂层厚度的无损测量方法。 对典型涂层进行触觉和无损检测。探头或带有集成探头的仪器直接放置在待测涂层上。涂层厚度显示在仪器上。 在ISO 2178:2016中，术语“涂层”用于诸如油漆和清漆、电镀涂层、搪瓷涂层、塑料涂层、粉末涂层、覆层等材料。 注:该方法也可用于测量非磁化贱金属或其他材料上的磁化涂层（见ISO 2361）。

ISO 2178:2016 specifies a method for non-destructive measurements of the thickness of non-magnetizable coatings on magnetizable base metals. The measurements are tactile and non-destructive on typical coatings. The probe or an instrument with integrated probe is placed directly on the coating to be measured. The coating thickness is displayed on the instrument. In ISO 2178:2016 the term "coating" is used for material such as, for example, paints and varnishes, electroplated coatings, enamel coatings, plastic coatings, powder coatings, claddings. NOTE This method can also be applied to the measurement of magnetizable coatings on non-magnetizable base metals or other materials (see ISO 2361).
