Testing Process
1. Send Samples
2. Check Requirements
3. Targeted Quotation
4. Both parties confirm and sign a contract to start the experiment
5. Completion of the experiment: The testing cycle (can be expedited) may vary depending on the sample and its testing items/methods, and can be consulted with an engineer
6. Issue a testing report and provide post service
