What is RoHS Testing?

The EU RoHS Directive (2011/65/EU), known as "The Restriction of the use of certain Hazardous Substances in Electrical and Electronic Equipment," restricts the use of certain hazardous substances in electrical and electronic products. The directive covers a wide range of products, including electronics, electrical appliances, medical devices, communication equipment, toys, security information products, and more. It applies not only to finished products but also to components, raw materials, and packaging, affecting the entire production chain.

RoHS Certification Process

1. Sample Submission or On-Site Sampling

- Send the relevant product to an HQTS laboratory for testing.

2. Sample Analysis

- The product is broken down into homogeneous materials for testing.

- Analyzes whether substances such as lead, cadmium, mercury, hexavalent chromium, PBBs, and PBDEs comply with RoHS directive requirements.

- Engineers compile a detailed test report.

3. Report Issuance

- If the product complies, a RoHS Compliance report and certificate are issued.

- If non-compliant, the manufacturer must replace non-conforming components with compliant alternatives.
