电缆.火花试验方法

[中文适用范围]： 本标准规定的火花试验方法适用于检测电缆绝缘或护套层的缺陷。对于没有外金属层的单芯电缆，一般过程被认为相当于对这些电缆的样品进行水中电压测试。本标准规定了火花试验设备的操作要求，以及各类试验设备的主要特性、功能参数和校准程序。 [外文原描述]： The spark-test method specified in this standard is intended for the detection of defects in the insulation or sheathing layers of electric cables. For single core cables with no outer metallic layer, the general process is accepted as being equivalent to subjecting samples of those cables to a voltage test in water. This standard specifies the operational requirements for the spark-test equipment, as well as the principal characteristics, functional parameters and calibration procedures for each type of test equipment.
