Full testing: The laboratory conducts standard testing based on the corresponding national standards for the product (such as electrical safety, EMC electromagnetic compatibility, wireless performance, etc and issues a type test report.
Rectification and retesting: If the test fails, the enterprise must rectify the product and resubmit samples for retesting until the test passes
