ActiveMonolithic (unshaped) refractory products—Part 2：Sampling for testing
不定形耐火材料 第2部分：取样
Application Summary AI generated
This standard specifies the procedures for obtaining representative samples of monolithic (unshaped) refractory materials, such as castables, plastics, and ramming mixes, for subsequent physical and chemical testing. It is applied in the quality control and acceptance testing of these materials within industries like steelmaking, cement, glass, and petrochemicals, ensuring that test results accurately reflect the properties of the bulk product. The standard is critical for manufacturers, testing laboratories, and end-users to verify compliance with specifications and performance requirements.
