测试和检验

Test and Inspection

除非另有说明，所有的测试在环境温度(5-35)℃,相对湿度(40-85)%的环境中进行。

Unless otherwise specified for the individual test, all tests shall be conducted at an ambient temperature of

(5-35)℃ and R.H. (40-85)%.

7.1 引线断裂试验：引线末端加力 0.5kg，在距管体 6mm 固定住并转 900，然后朝反向转 1800，然后恢复

原样，引线不松驰，不折断。

Lead bend test : With a 0.5kg weight attached to the end of the lead ,the same lead shall be clamped 6mm

from the rectifier body and clamp turned 90 degrees ,then 180 degrees in the opposite direction ,then returned to

the original position .The leads shall sustain this cycle without loosing and breaking.

7.2 正向压降试验：采用图 1 电路，IF=10mA，正向压降不得超过 75.2V。

Forward voltage drop test: Measured in Fig. 1 circuit at IF= 10mA,forward voltage drop (VF)shall not exceed

69V.

7.3 反向电流试验：采用图 2 电路，VR=24KV 单向正弦半波 50HZ，反向电流不得超过 2μA(25℃时)。

Reverse current test : Measured in Fig. 2 circuit at VR =24KV at the half sine wave of 50HZ,reverse current

shall not exceed 2μA at 25℃.
