关于投光灯的风力测试
在投光灯IEC60598-2-5中，条款5.6.5里有几个测试？有两个测试吗？一个是关于150km/h的测试？一个是关于2.4KN的测试？不是。只有一个测试。
150km/h形成的风力就是通过2.4kN的测试来模拟的。
2.4kN是通过ISO4354第6章的公式换算得来。 楼上正解 barondavids 发表于 2015-5-20 18:27 static/image/common/back.gif

感觉是两个不同测试，因为中间有段话：compliance shall be checked by inspection and, for floodlights for used above ground level outdoors, by the additional following test. Nezof 发表于 2015-5-21 08:29 static/image/common/back.gif

那是因为这个章节前面有的结构测试是通过“目视”来评估的。
对于特定的“floodlights for used above ground level outdoors”，它要承受指定风力，才做这个“额外”的测试。 barondavids 发表于 2015-5-21 09:56 static/image/common/back.gif

你是说 150km/h 这个测试是通过“目视”来评估的吗？ 五星四射 发表于 2015-5-21 10:06 static/image/common/back.gif

这个章节有很多段。以下这一段需要通过目测判断啊。
Parts of floodlights for mounting heights 3 mor higher which are fixed other than with at least two
devices, for example, screws or equivalent means of sufficient strength, shall have such extra protection
as to prevent those parts falling and endangering persons, animals and surroundings, if a fixing device fails under normal conditions. The points of attachment which allow the floodlight to rotate and
which are tested below are excluded from the requirements of this paragraph. 二楼正解，确实只有一个测试，就是使用2.4KN负载来模拟风力测试。 上面正解。
