There are various testing standards for silicone heat resistance, which are usually formulated by international or domestic authoritative organizations to ensure the performance stability and reliability of silicone materials in high temperature environments. The following are some common silicone heat resistance test standards and their key points:
I. International Standards
ASTM D573:
Overview: This is a standard developed by the American Society for Testing and Materials (ASTM) to evaluate the thermal stability and performance changes of silicone at high temperatures.
Test method: It usually involves placing the silicone sample in a constant temperature and humidity environment and observing the changes in its performance indicators such as thermal weight loss, tensile strength, and hardness through heating tests.
JIS K 6301:
Overview: This standard in the Japanese Industrial Standards (JIS) is also used to evaluate the heat resistance of silicone.
Test content: Similar to ASTM D573, JIS K 6301 also uses heating tests under constant temperature and humidity conditions to evaluate the thermal stability and heat resistance of silicone.
