4 Tests
4.1 General
Electrical and electronic systems/components shall be resistant to the specified chemical load test, i.e., there is no change in properties over the time and at the temperature of the test specified. If the test report proves that the electrical and electronic system/component is immune to the chemical load it is exposed to, it may be exempted from the test.
