7.TIL-B-36B describes a Dielectric Withstand Test of 4000 volts applied between live parts and accessible dead-metal parts.The voltage is reduced to 2500 volts if the enclosure is plastic and wrapped with foil for the test.At the time of the writing of UL 1993,UL staff could not agree with the CSA for the need for such high voltages,as it is inconsistent with what is required in other CSA standards,for example CSA C22.2,No.9.Furthermore it is cited that the equivalency to double insulation is being applied because the adapter is incapable of being grounded - nothing is said about internal voltages below the point where grounding would be needed.Nevertheless,the need for this test should be considered and it may in many times easier to do the test than to rationalize why it need not be done.
8.TIL-B-36B describes a Leakage Current Test when measured from an accessible dead-metal part or foil wrapped around a plastic enclosure.At the time of writing UL 1993,UL staff could not agree with the CSA for the need for this test,at the time and still true today,the test adds to the cost of the investigation when we have never experienced test failures in doing this in other categories.Nevertheless,the need for this test should be considered.
9.TIL-B-36B describes the Harmonic Distortion test is to be conducted on both magnetic and electronic ballasts.At the time of writing UL 1993,UL staff had the opinion,and industry agreed that it was the introduction of switching power supplies that created most higher ordered harmonics.CSA is still reporting that they have not been conducting this test because the provincial authorities have not been asking for the measurement.
10.The Impact Test (Clause 5.8) is a ball drop impact,where the impact force is a function of the product weight.From Table 2,the forces are less than the 3 foot product drop impact conducted by UL.
7.TIL-B-36B描述一个介电经得起考验的4000伏特应用带电部件和易于dead-metal之间的部分.电压降至2500伏如果外壳塑料包装,用铝箔为考试做准备.在当时的写作UL 1993年,UL员工不能赞同CSA的需要这么高的电压,因为它是不符合所需要的其它加拿大工业标准协会(CSA)标准,例如CSA中已有标示,9号.而且它是引用的学历,双重绝缘正被应用,因为该适配器是不能脚踏实地,一切都说关于内部电压低于地方需要接地.然而,需要进行测试,而且它可能应该考虑在许多次容易做测试超过理顺它为什么不用做.
8.TIL-B-36B描述了泄漏电流测试测量是从一个容易dead-metal部分或铝箔裹在一个塑料外壳.目前UL 1993年,UL员工不能赞同CSA的需要,同时还有真实的今天,测试增加成本的调查,当我们从未经历过失败在做这试验在其他类别.然而,需要进行测试.
9.TIL-B-36B介绍谐波畸变试验进行了两个磁场和电子镇流器.目前美国UL、UL人员曾在1993年进行的一项民意调查显示,与行业的同意,它是引入开关电源,创造了大多数高等命令谐音.报导说,他们仍予尚未进行测试,因为这个省官员并没有被要求测量.
10.这个影响测试(条款)是一个球5.8跌落冲击,那里的冲击力的产品的重量.从表2、力量是小于3英尺的产品通过了美国UL跌落冲击进行.
