GB/T 5137.5-2020
Test methods of safety glazing materials used on road vehicles—Part 5: Resistant-to-chemical and resistant-to-temperature changes test

GB/T 5137.5-2020 specifies test methods for the chemical resistance and resistance to temperature changes of plastic-glass composites, rigid plastics, and flexible plastics used in automobiles, with the chemical resistance load method applicable only to rigid plastics. The chemical resistance test assesses material stability through immersion or load methods using specific chemical reagents, involving equipment such as metal/glass containers and metal supports. The resistance to temperature changes test simulates extreme environments ranging from -40°C to 80°C, utilizing test chambers, feeler gauges, and other instruments to evaluate the material's resistance to cracking and deformation. The standard defines test conditions, sample requirements, and operational procedures, providing a unified basis for verifying the performance of automotive safety glass under complex chemical environments and temperature fluctuations, thereby ensuring vehicle safety during use.
