3.1.2 出厂试验的目的，是为了检查开关设备在制造过程中所用材料、电器元件及加工工艺是否符合产品图样与技术要求。这是制造厂为保证出厂产品与通过型式试验的产品一致性所必须要进行的试验。
3.1.2.1 出厂试验必须在每台产品上进行。
3.1.2.2 出厂试验项目包括：
a) 结构检查；
b) 机械特性和机械操作试验；
c) 主回路1min工频耐压干试验及辅助回路的工频耐压试验；
d) 主回路电阻测量；
e) 辅助电气装置试验；
f) 接线正确性检查。

3.1.2 The purpose of production test is to check if the material, electrical components and technology of the products fulfill the drawings and technical requirements. This is for the manufacturer to make sure that the samples passed the type test are just the same as the products in the factory.
3.1.2.1 Production test should perform on each products sent to the lab.
3.1.2.2 there are several items in the production test:
a)structure check
b)Mechanical endurance and mechanical operation test
c)1min dry power frequency test of main circuit and the power frequency withstand test of the auxiliary circuit
d)main circuit resistance test
e)auxiliary electrical device test
f)Check the order of the circuit
