描述了一种试验方法，该方法可以初步区分类似绝缘材料在暴露于靠近其表面的高压、低电流电弧放电时的抗损坏性。由于该试验方法方便且试验所需时间短，因此适用于试验材料的初步筛选、检测配方变化的影响以及质量控制试验。

Describes a test method which can provide preliminary differentiation between similar insulating materials, with respect to their resistance to damage when exposed to high-voltage, low-current arc discharges, occurring close to their surfaces. Due to its convenience and the short time required for testing, the test method is applicable for preliminary screening of test materials, for detecting the effects of changes in formulation and for quality control testing.
