Arc tracking test

Arc tracking test
The objective of this test is to simulate a phenomenon where a small electrical short or arc (caused by a number of factors) will burn the surface of an insulating material. This leaves a carbon deposit (or track) that creates a path for electricity. Repeated arcing and tracking leads to unintended current paths, high temperatures, and can potentially lead to ignition.

帮忙理解一下上面的测试?最好能够翻译出来
这个测试标准是哪个呢？
这是个很有用的测试，望大家学习分享一下~

与IEC 的PTI或CTI测试类似。

非常感谢楼上的朋友~电弧放电测试确实是一个很实用的试验~
这个在国外的测试中要求的比较多！

没见过此标准，试翻译一下：
电弧起痕试验
本试验的目的是模拟轻微的电气短路或起弧(由众多因素产生)使绝缘材料表面燃烧的现象。该现象留下产生电气通路的碳附着(或起痕)。重复的起弧和起痕导致不需要的电流通路，高温，及可能导致引燃。

我只看过IEC 60112
可以从IEC 60112得到启发。IEC 60112中的漏电起痕失效的判断是过电流装置动作，或持久火焰。
而且这种失效不是因为在电极间的电弧产生的。

那么可以LZ所述测试，是让放在塑料上的电极间产生电弧。
