18、ical equipment 3 Test procedure 3.1 The insulation resistance shall be measured between all terminals which are insulated from each other and also between all terminals and the housing. 3.2 The test shall be performed both with the relay or contactor energized and de-energized. 3.3 The test shall be
19、 performed in accordance with ISO 2678. 3.4 The test voltage shall be 500 V d.c. 3.5 The specified insulation resistance shall be reached within 2 min. 3.6 During the test in the de-energized state the coil terminals shall be connected to each other. 4 Test criteria The insulation resistance of the
20、relay or contactor shall be greater than the values specified in the product standard. 1) In preparation at the date of publication of this standard.
