UL1598标准中，吊重测试的方法及判定标准

UL1598标准是灯具厂商办理美国安规认证时，常遇见的一个标准。之前有遇到客户来咨询吊重测试的相关问题，今天美德小编为您讲解UL1598标准中，吊重测试的方法及判定标准，一起来了解下吧！

测试方法：

安装支架需通过吊重测试，四倍于灯具总重量，吊重1小时，吊重受力方向为支架实际安装方向。当安装支撑多于一个时，分别按以下来测试：

a) 当灯具的重量小于 25 磅时，每个支撑都需要做一次吊重测试；

b) 当灯具大于 25 磅时，吊重按现场安装方式来测试。

Where more than one support was provided, the load was distributed as follows: 

a) where the parts supported were no more than 11.3 kg (25 lbs), the full load was applied to each support; or

b) where the parts supported were more than 11.3 kg (25 lbs), the distribution of the load was similar to that encountered in the field.

判定标准：

不能偏斜或变形致使电气间隙减少或损害产品安全的情形发生
