16.5.7.1 A sample of the water shield shall be mounted on the luminaire for impact conditioning. The
sample shall be subjected to a 4.1 J (3 ft·lb) impact from the steel sphere of Clause 19.21 from a vertical

1,Water shield 具体指的是什么?用作防雨和防触电保护的灯罩算不算是.
2,是不是所有的wet location luminaire都要做这个测试．

老弟,标准13.4.4.3和4.4讲得很明白:

13.4.4.3 A glass or polymeric water shield of a ground-mounted recessed luminaire shall be subjected to the impact conditioning test of Clause 16.5.7 and shall then comply with the immersion test of Clause 16.5.4.

13.4.4.4 A wooden water shield less than 13 mm (0.5 in) thick shall be subjected to the impact conditioning test of Clause 16.5.7 and shall then comply with the applicable rain, sprinkler, or immersion test.
