GB/T 2423.20-2014
Environmental testing—Part 2:Test methods—Test Kd: Hydrogen sulphide test for contacts and connections

This standard is used to evaluate the accelerated test method for performance changes, such as contact resistance, caused by corrosion in silver or silver alloy contact points and connectors in environments containing hydrogen sulfide (H₂S) gas. The core equipment for conducting this test is a chemical gas corrosion test chamber (also known as a hydrogen sulfide test chamber), which must be designed to ensure stable maintenance of the specified hydrogen sulfide gas concentration, temperature, and humidity conditions inside the chamber. During the test, hydrogen sulfide analyzers or gas detectors are typically required to accurately monitor and control the hydrogen sulfide concentration inside the chamber. This method is particularly suitable for comparative testing and process quality evaluation of products such as electrical connectors and terminals.
