It shall be used together with EN 2349-100. 2 Normative references The following referenced documents
18、 are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 2349-100, Aerospace series Requirements and test procedures for relays and conta
19、ctors Part 100: General requirements 1)ISO 2678, Environmental tests for aircraft equipment Insulation resistance and high voltage tests for electrical equipment 3 Test procedures 3.1 The test voltage shall be applied between all terminals which are insulated from each other and between all terminal
20、s and the housing. 3.2 The test shall be performed both with the relay or contactor de-energized and energized. 3.3 The test shall be performed in accordance with ISO 2678. 3.4 The test duration shall be as follows: for batch acceptance and acceptance testing: 2 s to 5 s; for certification testing:
21、1 min. 3.5 During the test in the de-energized state the coil terminals shall be connected to each other. 4 Test criteria The dielectric strength of the relay or contactors shall conform to the values specified in the product standards. The relay or contactor shall not be damaged during the test. Th
