QJ 990.13-1986 "Coating inspection method, thermal insulation coating specific gravity determination method" is applicable to the inspection of main and auxiliary products to be coated with thermal insulation coatings. This standard specifies the methods and steps for the measurement of thermal insulation coating specific gravity. Specimens require the use of metal sheets with dimensions of 10x10x10mm, Coating thickness greater than 5mm, and after coating through drying. Equipment used includes scales and vernier calliper with an accuracy of 0.0001 grams. At least three measurements are required for each batch of samples to ensure the accuracy and Reliability of the results.
