The ISO 1463 standard specifies the Measuring method of Coating thickness of metals and oxides, which is determined by Microscope method. This method observes the cross-section of coatings through Microscope and accurately measures the thickness of coatings, which is suitable for high-precision detection of thin coatings. Microscope method has high resolution and can provide detailed coating structure information, which is widely used in the quality control and research field of metal and oxide coatings. Through this standard, users can ensure the accuracy of Coating thickness, providing reliable data support for coating performance evaluation and application.
