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.
