16.21.1 Strain relief for ?exible cords
16.21.1.1 A pull force of 156 N (35 lbf) shall be applied for 1 min to the ?exible cord in a direction
perpendicular to the plane of the entrance into the luminaire.
16.21.1.2 Test results shall be acceptable if there is no:
(a) movement of the ?exible cord of more than 1.6 mm (0.063 in); and
(b) breaking of the conductor or loosening of the wiring connections inside the enclosure of the
luminaire.
以上的测试是怎样做的啊,如果有那个高手能画一个简单的示意图看看,那就真的不胜感激啦.
