灌胶的LED驱动豁免电线拉力测试
为什么灌胶的LED驱动,电线拉力测试在UL里面可以豁免(如下是从UL test record中摘取的)The following tests were waived due to the Rationale specified as below.
Test NameStandard ParagraphRationale
HUMIDITY EXPOSUREUL 8750- 8.12.1CSA 250.13- 9.12.1The devices are fully potted
WATER EXPOSUREUL 8750- 8.12.2CSA 250.13- 9.12.2
CORD STRAIN AND PUSHBACK RELIEF TESTUL 8750- 8.8CSA 250.13-9.8
BONDING CIRCUIT IMPEDANCEUL1598 Clause 17.2Evaluated by end product
我觉得奇怪,因为灌胶有灌硬胶的和软胶的,硬 胶的还好,软胶的有些防拉力作用很小的。 你凭啥说是因为灌胶可以豁免? 我没有听说这个事情。
我看了你这个报告,应该是产品做的是RC认证类型,拉力测试可以再成品中考量,不是豁免的问题。
