GB/T 13767-1992 is a standard for measuring the heat resistance of Spinning & weaving products. It places Spinning & weaving samples in a specific high temperature environment and operates at a set time and heating rate. The heat resistance is evaluated by observing the changes in the sample Appearance such as Color change, fiber damage, size cissing, etc. The standard specifies in detail the test equipment, sample preparation, and test process to provide a reliable method for uniformly testing the heat resistance of Spinning & weaving products. Help the mass control and performance optimization of Spinning & weaving products in high temperature scenarios.
