ASTM D3925-02 (2022) Standard Practice for Sampling of Liquid Coatings and Related Chromadizing Coatings provides a standard method for sampling liquid coatings and their chromadizing coatings. This standard is primarily used to guide sampling from production batches or storage containers to ensure that the samples taken are representative. The code details the number, location, tools, and procedures of sampling to minimize sample deviation and ensure the accuracy and conformity of test results. This is essential for the Coatings industry in quality control, R & D, and performance testing to ensure that coatings meet relevant mass requirements and ensure the conformity of the final product.
