Update time : 2025-02-15

RoHS, officially known as the "Restriction of Hazardous Substances Directive," is a regulation aimed at limiting the use of specific hazardous substances in electrical and electronic products. JJR Laboratory, as a professional testing institution, has conducted in-depth research on the RoHS directive and provides businesses with detailed and accurate regulatory interpretations, helping them understand the specific requirements and significance of ROHS Testing.

 

What does RoHS mean?(图1)


The European Union implemented the first version of the RoHS directive (RoHS 1.0) on July 1, 2006, which explicitly restricted the use of six hazardous substances, including lead (Pb), cadmium (Cd), mercury (Hg), hexavalent chromium (Cr6+), polybrominated biphenyls (PBBs), and polybrominated diphenyl ethers (PBDEs). Products that violate these restrictions may face severe penalties when exported to the EU.

 

RoHS 2.0

On June 4, 2015, the EU updated RoHS 2.0 through Directive (EU) 2015/863, adding four phthalates (DiBP, DBP, BBP, and DEHP) to the restricted substances list, increasing the total number of restricted substances to ten.

 

Beyond the EU, multiple countries and regions worldwide—including China, the United States, Japan, and South Korea—have also implemented similar RoHS regulations, making RoHS Compliance a fundamental requirement for electronic and electrical products to enter international markets.

 

Importance of RoHS Testing

1. The Necessity of RoHS Testing

Conducting RoHS testing is crucial for manufacturers, as non-compliant products may face market rejection or legal and financial consequences. JJR Laboratory is equipped with advanced instruments and an experienced technical team, offering comprehensive, fast, and professional one-stop services. Our laboratory information management system ensures high efficiency and accuracy in test data and reports.

RoHS 1.0 and China RoHS

With its advanced equipment and professional team, JJR Laboratory efficiently conducts RoHS testing for manufacturers, ensuring compliance with regulations and mitigating legal and economic risks.

 

1. The Six Restricted Hazardous Substances and Their Limits:

- Lead (Pb): 1000 mg/kg

- Cadmium (Cd): 100 mg/kg

- Mercury (Hg): 1000 mg/kg

- Hexavalent Chromium (Cr6+): 1000 mg/kg

- Polybrominated Biphenyls (PBBs): 1000 mg/kg

- Polybrominated Diphenyl Ethers (PBDEs): 1000 mg/kg

 

2. RoHS 2.0 Updates

RoHS 2.0 expanded the restricted substances list by adding four phthalates, with limits set at 1000 mg/kg or 100 mg/kg.

 

RoHS 2.0 Testing Items and Methods

RoHS 2.0 testing includes lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyls, polybrominated diphenyl ethers, and the four restricted phthalates. The testing methods and instruments used include:

 

- ICP-OES testing according to IEC 62321-5:2013

- ICP-OES testing according to IEC 62321-4:2013+AMD1:2017CSV

- UV-VIS testing according to IEC 62321-7-1:2015

- GC-MS testing according to IEC 62321-6-2015

- GC-MS testing according to IEC 62321-8-2017
