EU ROHS testing project for headphones
1. Overview of ROHS Directive
- Definition: ROHS (Restriction of the Use of Certain Hazardous Substances Directive) is a regulation issued by the European Union for electronic and electrical products, which aims to limit or prohibit the use of six hazardous substances including lead, mercury, cadmium, etc. in electrical and electronic equipment.
- Key facts:
- It was officially implemented on July 1, 2006.
- 2011/65/EU (RoHS2.0) came into effect on July 21, 2011.
- On June 4, 2015, the European Union issued Directive (EU) 2015/863, adding four phthalates (DEHP, BBP, DBP, DIBP) to the list of restricted substances, bringing the total to 10 items.
- Major controversy: Some manufacturers believe that the additional testing items and restricted substances will increase production costs, but supporters believe that this will help environmental protection and consumer health.
2. Test items
- Metal material test: lead (Pb), cadmium (Cd), mercury (Hg), hexavalent chromium (Cr6+).
- Non-metal material test: lead (Pb), cadmium (Cd), mercury (Hg), hexavalent chromium (Cr6+), polybrominated biphenyls (PBBs) and polybrominated diphenyl ethers (PBDEs).
- New phthalates: di(2-ethylhexyl) phthalate (DEHP), butyl benzyl phthalate (BBP), diisobutyl phthalate (DIBP).
- Key facts: All electrical and electronic equipment must meet the requirements of 10 restricted substances from July 22, 2019.
- Real world example: TWS headphones must pass these test items when exported to the EU to ensure compliance with ROHS2.0 standards.
3. Testing process
- Definition: The testing process for ROHS certification of headphones includes sample submission, document review, data evaluation and report issuance.
- Key facts:
- Sample submission: Customers need to submit samples to be tested to the testing agency and provide relevant product information and technical documents.
- Document review: The testing agency reviews the information provided by the customer, including the product material list and instructions for use.
- Data evaluation: Evaluate the test results to determine whether the sample meets the ROHS standard.
- Report issuance: After strict review, a detailed quality inspection report is issued.
4. Testing standards and references
- Definition: The testing standards for ROHS certification of headphones are mainly based on EU regulations and international standards.
5. The significance and impact of certification
- Definition: ROHS certification can not only protect the health of consumers, but also enhance the market recognition of products.
- Key facts:
- Market access: ROHS certification is an important step to enter the EU market.
- Brand competitiveness: Through ROHS certification, companies can show consumers the environmental characteristics of their products and enhance the brand's market competitiveness.
- Major controversy: Some companies believe that ROHS certification increases production costs, but supporters believe that it helps improve product quality and brand image.
