各位高手下面这个是什么意思啊？牛人站出来，讨教下

71.2 Power-supply cord

71.2.1 When tested in accordance with 71.2.2, the strain relief means provided on the flexible cord shall withstand for 1 minute, without displacement, a pull of 35 pounds-force (156 N) applied to the cord with the connections within the alarm disconnected.

71.2.2 A 35 pound-mass (15.9kg) weight is to be suspended on the cord and supported by the alarm so that the strain relief means are stressed from any angle that the construction of the alarm pemits. The strain relief does not comply when, at the point of disconnection of the conductors, there is such movement of the cord as to indicate that stress has resulted on the connections.

71.3 Field-wiring leads
71.3.1 each lead employed for field connections, including a battery clip lead assembly, shall withstand for 1 minute a pull of 10 pounds-froce (44.5N) without any evidence of damage or of transmittal of stress to internal connections. A connector used in the lead assembly shall withstand a pull of 5 pounds-force (22.3N) without any evidence of damage, transmittal of stress to internal connections, or separation.

不管是IEC还是UL的不同的标准拉力要求稍微有点区别。

43.2 有关43.1, 经受条件的样机以比在正常温度测试中在转尾组装上测量的温度高10°C但不小于70°C(158°F)的条件下保持7小时.

有完整的标准不,我产品是电热水壶,UL1082标准,是否也要做此测试.
