Scope

This part of GB/T 20875 specifies the test method for determining the hydrolysis stability of thermoset molding materials made from room-temperature or high-temperature curing resins when they are subjected to the combined effects of water and high temperature.
The test method in this part is suitable for measuring irreversible changes in mechanical and electrical performance, but no mechanical stress is applied to the samples.
