EN 2349-309:20064 1 Scope This standard specifies a method for testing th
16、e outgoing interference voltage (exported spikes) of internally suppressed relays and contactors only. The relay or contactor shall be subjected 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 s
17、pecified in the product standard. It shall be used together with EN 2349-100. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the refe
