灯具如何做stability test!
我们有一款摇臂灯,去年送CTL测试可以过8度测试的,但是今年却不行了.CTL解释由于CSA的要求不同于UL要求,虽然UL要求可以过,但是CSA不一定能过.由于手上没有CSA标准,也不知是如何要求的.
但我希望能够在这里与大家讨论一下稳定性测试,特别是这个产品要去美加市场的.

是用最不利的角度去测试, 测试时须附带灯泡

如果摇臂可以调的话，调到最不利位置，然后放在一个8度倾斜的平台上，看灯会不会翻倒，应该是ETL吧？标准应该是一样啊，相关的话题，论坛上已经有了，你可以搜索一下看看

132 Stability Test
132.1 General
132.3 Test method – units with flexible or articulated arm
132.3.1 When the portable luminaire has a flexible or articulated arm, the arm is to be bent before the lamp is placed on the inclined plane, starting at the lower end of the arm, to form a quarter circle that a line joining the ends of the arm make an angle of 45 degrees with the horizontal. When a flexible or articulated arm is off-center with respect to the base, the arm is to be bent in the direction that results in tip over. When the unit has more than one flexible or articulated arm, one of the arms is to be adjusted as for a unit having a single arm, and the other arm or arms are to be extended vertically.
Exception No. 1: When the unit is not stable on a flat horizontal surface in a particular position, the unit is not required to be tested in that position.
Exception No. 2: Any position of intended use as specified in the manufacturer’s instructions is determined to be the normal operating position.

如果是最不利的位置,应该很少有产品可以通过测试.
请参照UL153:

就是说,如果是有关节的灯,就要将手臂调成四分之一的圆弧,或者说最后一条手臂与水平面成45度角.
