GB/T 4513.7 - 2017 is the seventh part of the standard for amorphous refractory materials, focusing on the determination of preforms. It specifies the requirements for the inspection of amorphous refractory preforms, covering basic inspections such as Appearance mass and dimensional deviation, as well as performance tests such as compressire strength and volume density. The standard specifies the required equipment and operation process, and obtains various performance data of preforms through the standardized inspection process. These data can help manufacturers control the mass of preforms, provide reliable reference for industrial users when selecting preforms, and ensure their applicability and Reliability in high temperature operation scenarios.
