Δ

根据

IEC68-2-21（GB2423 .29）试验U 进行试验。

试验

Ua：拉力10N，持续10 S；

试验

Ub：弯曲90°，拉力5N，持续10 S；

扭转

180°，拉力5N，持续10 S。

在

Fasten the body and apply a force gradually to each lead until

10N and then keep for 10sec, Hold body and apply a force to

each lead until 90°slowly at 5N in the direction of lead

axis and then keep for 10sec, and do this in the opposite

direction repeat for other terminal. After recovering 4~5h

be measured.
