ISO 2178:2016标准是一项涂层厚度测量的标准，主要适用于非磁性涂层在磁性基材上的测量。该标准规定了使用磁性方法测量涂层厚度的步骤和要求，以确保测量结果的准确性和可重复性。

该标准适用于涂层厚度在1μm至10mm之间的非磁性涂层，如金属、氧化物、电镀、喷涂等。在测量过程中，需要使用磁性感应仪或磁性涂层厚度计等设备，以测量涂层表面和基材之间的磁场强度差异，从而计算出涂层的厚度。

在使用磁性方法测量涂层厚度时，需要注意以下几点：

1. 磁性感应仪或磁性涂层厚度计的灵敏度应符合要求，以确保测量结果的准确性。

2. 测量前需要对磁性感应仪或磁性涂层厚度计进行校准，以消除误差。

3. 测量时需要保证涂层表面和基材之间的磁场强度差异足够大，以确保测量结果的可靠性。

4. 测量时需要避免磁性感应仪或磁性涂层厚度计与其他磁性物质接触，以避免干扰测量结果。

需要注意的是，该标准不适用于非金属涂层、磁性涂层和非平整表面的涂层。对于这些涂层，需要使用其他测量方法进行测量。
