本标准适用于: -直流电压介电试验 -交流电压介电试验 -冲击电压介电试验 -脉冲电流试验 -结合上述各项进行测试 -电容和介质损耗测量 本标准仅适用于额定电压高于1000 V的设备上的试验。 给出了应用修正系数将试验数据转换为标准大气条件的程序。 本标准还规定了当测试对象的外部绝缘处于干燥、潮湿或污染状态时，测试设备的程序。

This standard is applicable to - Dielectric tests with direct voltages - Dielectric tests with alternating voltages - Dielectric tests with impulse voltages - Tests with impulse currents - Tests with combinations of the above - Capacitance and dielectric loss measurements This standard is applicable only to tests on equipment with a rated voltage above 1000 V. Procedures are given for applying correction factors to convert test data to standard atmospheric conditions. This standard also specifies procedures for testing equipment when external insulation of the test object is to be subjected to dry, wet, or contaminated conditions.
