AS/NZS 3112插头标准的几个疑问。。

q529891012

第一，对插头的试验中，有很多是关于力测试的，要求施加力在10秒内从0上升到规定值，想问大家的是在实际试验中，如何保证在10秒内力均匀增加到规定值的？同时有些试验有温度限制，需要在烘箱里面进行，象庞大的静态拉力机肯定不能放在烘箱里的。

第二，关于2.13.9.1 movement of pins条款

For all plugs, the point of application of the force shall be 14 ±0.5 mm from the face of the
plug along the pins, and the direction of the force shall be—
(a) in both directions along the line perpendicular to the plane of the pin, and passing
through the centre of the pin; and
(b) in that plane in both directions along a line at right angles to that specified in
Item (a)

一共施加2个力还是4个力，分别沿着什么方向？
