It shall be used together with EN 2349-100. 2 Normative references The following referenced documents are indispensable for the applica

18、tion 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.

19、ts 1)3 Test procedures 3.1 Bounce time shall be measured, both on the normally-open and normally-closed contacts, by applying the rated voltage on and off. 3.2 The bounce time includes both the initial bounce, when the contacts close or open for the first time, and all additional bounces, see Figure

20、s 2 and 3. 3.3 The contact load shall be between 5 mA and 100 mA. The open contact voltage shall be 6 V d.c. max. for relays or contactors with ratings of up to and including 25 A, and 28 V d.c. max. for relays or contactors with ratings above 25 A. 3.4 For qualification tests, five measurements sha

21、ll be taken and recorded. 3.5 Figure 1 shows a typical test circuit. 3.6 The test shall be performed in such a way that the records cover all occurrences of bounce. 4 Test criteria The relay or contactor shall not exceed the bounce times specified in the product standard. 1) In preparation at the da
