RoHS compliance testing process:

1. Sample preparation: Collect electronic and electrical products to be tested and prepare test samples according to standard requirements.

2. Detection: Conduct chemical analysis and physical testing on the sample to determine if it contains prohibited substances.

3. Report preparation: Write a test report based on the test results, indicating whether the sample meets ROHS standards.

4. Review and certification: Submit test reports and application materials for review and certification by the certification agency.

The detection of ROHS certification mainly targets prohibited substances in electronic and electrical products, requiring chemical analysis and physical testing. The specific testing methods and standards may vary depending on the product type and certification agency, and generally require testing through authoritative laboratories.
