GB/T 17339-1998 stipulates the test method for chemical etching resistance and temperature change resistance of automotive safety Glass. The chemical etching resistance of Glass samples is detected by placing them in specific chemical reagents to simulate different chemical environments; at the same time, the temperature cycle change test of the samples is carried out to observe the performance of Glass under drastic temperature changes. The standard specifies the type of reagent, concentration, soaking time, temperature change range, rate and other parameters to provide a unified method for evaluating the Reliability of automotive safety Glass in complex use environments to ensure driving safety.
