GB 3186-1982 "Sampling of Coating Products" standard specifies the sampling methods and requirements for Coating products during the inspection process. The standard applies to various types of Coating products, including liquids, powder coatings, etc., and aims to ensure that the samples are representative in order to accurately reflect the mass of Coating products. The standard details the sampling procedures, the number of samples, sampling tools, and the requirements for Coating sampling in different Encasement forms to ensure that samples that meet the standard requirements are obtained from batch products for testing. Through scientific and reasonable sampling methods, the fairness and accuracy of mass inspection of Coating products are guaranteed.
