18、ordance with EN 2349-100 and the rated contact load. 3.2 Test procedures Each normally closed and normally open contact shall be loaded with 25 % of the resistive load as specified in the product standard. The open contact voltage shall conform to the value specified in the product standard. During
19、this test the coil of the relay or contactor shall be energized at the rated voltage. The contacts shall be monitored for opening and closing in the sequence specified.

In addition: the test sample shall withstand the number of cycles without malfunction; there shall be no mechanical damage; there shall
21、 be no sticking or seizing of contacts. Test in accordance with EN 2349-301: Pick-up and drop-out voltage.
