How to handle the testing report of the sample? What are the scope and standards of testing? Today, the editor of Baijian Testing will take you to understand the specific tests required for the relevant testing business. At the same time, Baijian can also design testing plans based on corresponding testing standards or according to your needs

Testing process

1. Sending samples

2. Checking requirements

3. Targeted quotation

4. Both parties confirm, sign a contract, and start the experiment

5. Completing the experiment: The testing cycle (can be expedited) may change according to the sample and its testing items/methods, and engineers can be consulted

6. Issuing the testing report and providing post service.

Testing items:

Partial parameters, breaking capacity, size and structure, time/current characteristics, maximum continuous power consumption, marking, fuse temperature, voltage drop, durability test, pulse test, layout of fuse, temperature rise and dissipation power verification, action verification, all items, bending and twisting, tension, thrust, breaking current, mechanical requirements, marking (wiping test), marking, checking Tf, checking Tm and connecting it to electrical strength and insulation test edge resistance.
