19、ce 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: 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 re
20、lay or contactors shall conform to the values specified in the product standards. The relay or contactor shall not be damaged during the test. The leakage current shall not exceed 1 mA. 1) In preparation at the date of publication of this standard. EN 2349-303:2006blankBS EN 2349-303:2006BSI389 Chis
