This standard provides procedures for obtaining representative samples of traffic coatings from on-site storage containers. Correct sampling is essential for assessing the mass of traffic coatings, ensuring that the samples accurately reflect the composition of the overall product. The standard details methods for sampling from different containers, including mixed and unmixed Coatings. By employing appropriate sampling tools and techniques, the deviation of samples can be reduced and the accuracy of test results can be ensured. This is of great significance for evaluating key indicators such as solids by volume, Resin content of Coatings.
