18、e operating, will ignite an ambient explosive atmosphere prevalent in aircraft applications. This test is not necessary for switches which are enclosed in housings (casings) designed to prevent flame or explosion propagation. Test Method: Switches shall be tested in accordance with Method 109 of MIL
19、-STD-202. Switches shall be operated at their maximum rated dc inductive current at the rated voltage. Criteria: The explosive mixture in the test chamber surrounding and external to the switch shall not explode whether or not an explosion occurs within the switch. Switches shall be electrically ope
20、rable after the test.
