Explosion-proof distribution box type test
The purpose of the type test is to verify design performance stereotypes distribution box meets the standard requirements of the enterprise .
Type test is to test new product trial production must be carried out . Only when the product design , manufacturing processes, use of raw materials or components structure changes that may affect the distribution box explosion-proof performance , only need to re- type test of the projects . Normal products once every five years . Any type test sample from the factory inspection of products, the random selection of two test , two sample tests are qualified to consider the type test qualified.
