GB/T 4513.2 - 2017 is the second part of the standard for amorphous refractory materials, focusing on standardizing the sampling operation. It clarifies the scope of application of sampling, covering different types of amorphous refractory materials. Describe the selection of sampling tools in detail, and specify the reasonable sampling position, quantity and method in the batch product to ensure that the sampled product can represent the overall material characteristics. By strictly following this standard sampling, it can provide representative samples for subsequent material performance testing, ensure that the test results truly reflect the product mass, and help the production, testing and other links to accurately evaluate amorphous refractory materials.
