7.5 Dielectric tests The purpose of these tests is to verify that the insulation of the test specimen will withstand the voltages shown in Table 1. The test voltage shall be applied to the parts of the connector that are energized in service. The test point, if any, shall be grounded during these tests. 7.5.1 AC withstand voltage test The test voltage shall be raised to the value specified in Table 1 in not more than 30 s. The connector shall withstand the specified test voltage for 1 min without flashover or puncture.
