Define the laboratory assignment
CIRCUDOWN can arrange third-party testing with IDFL, SGS, QTEC and Guangjian. The required institution, service scope, timing and fees must be agreed for the project. No report number or blanket laboratory endorsement is claimed on this website.
Send a complete sample brief

- Additional cleanliness, moisture or other tests.
- Report recipient and permitted disclosure.
Interpret the result in context
Read the tested parameters, sample description and method alongside the result. A passing result for one parameter does not establish compliance with untested requirements. Keep the report linked to the sample and use an agreed process for production-lot approval.
