GB/T 4513.5 - 2017 is the fifth part of the standard for amorphous refractory materials, focusing on the preparation and pretreatment of the sample. It specifies a series of operation procedures from raw material selection to sample molding, covering key links such as mixing and stirring, mold selection, molding pressure, etc., to ensure the preparation of representative samples. At the same time, clarify the conditions of sample pretreatment, such as drying, curing temperature and duration. Standardized preparation and pretreatment are the basis for subsequent accurate determination of the performance of amorphous refractory materials. They can provide reliable samples for production enterprises and research institutions to ensure the accuracy and comparability of relevant test results.
