How to do the test report? Why do you need to do product inspection? Third-party testing institutions provide product testing services in various industries, and there are many cooperative laboratories across the country, mainly serving companies, enterprises, individual businesses, universities and scientific research.
Testing process
1, sending samples
2, checking requirements
3, targeted quotation
4, both parties determine, sign a contract, start
the experiment5, complete the experiment: the testing cycle (can be expedited) will be changed according to the sample and its testing items / methods, you can consult the engineer
6, issue a test report, and provide post-service.
