ASTM D1005-1995(2020) 《Standard Test Method for Measurement of Dry-Film Thickness of Organic Coatings Using Micrometers》 Related products

The ASTM D1005-1995 (2020) standard details four procedures for the measurement of dry-film thickness of organic coatings using Micrometers. Procedures A and B use a fixed Micrometer for the measurement of coatings and free films on rigid surfaces on a plane; Procedures C and D use a handheld Micrometer, which is equally applicable to both of the above situations. The standard states that the deformability of the coating may affect the accuracy and accuracy of the measurement, and is not suitable for coatings that are easily deformed under the load of the measuring instrument. In addition, the uniformity of the substrate also affects the film thickness measurement results of the coating on the laboratory test plate. The standard emphasizes safety and health responsibilities and follows the principles of international standards.
