The relay or contactor shall be subjected
18、to tests to determine that outgoing interference voltages, which are produced by de-energizing the coil of the switching device, do not exceed the values specified in the product standard. It shall be used together with EN 2349-100. 2 Normative references The following referenced documents are indis
19、pensable 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 contactors Part
20、 100: General requirements 1)3 Test procedures 3.1 Before carrying out the interference voltage tests, the maximum coil voltage shall be applied with reversed polarity to the coil terminals for at least 2 s, to ensure that the inverse voltage of the coil circuit is greater than the maximum coil volt
21、age and correctly polarized. 3.2 The number of tests shall be as follows: for acceptance testing: 1; for qualification testing: 3. 3.3 An oscilloscope shall be required for type testing.
