Compliance is checked by subjecting the insulating material for 1 min to 750 volts with a substantially sinusoidal waveform having a frequency of 50Hz or 60 Hz. this provision does not exclude the testing of the material as situated within the tool. proving care is taken to ensure that materials not under consideration are not subject to the test voltage。This applies only to materials, if they were to fail to insulate, would subject the user to a shock hazard from a hazardous voltage. this test does bot apply to materials that provide only a physical barrier to contact. as such, an uninsulated energized part shall be within 1.0 mm of the material surface to be considered for this requirement

绝缘材料需要经过一般正弦波形功率50Hz or 60 Hz的750伏特的电压一分钟，这个规定也包括已用在工具上的材料。以此确保未经过保护措施的材料，不能通过此测试电压。

此要求只针对材料，如果材料不绝缘，那用户会遭到危险电压的电击伤害。此测试适用于只提供物理屏障的材料测试。因此一个非绝缘带电部分应在材料表面有1.0毫米之内才符合此要求。
专业的词汇实在是无能为力。。我写下来只供你看一下。。然后结合自己这方面的知识。。给出正确的答案。。
