What does RoHS mean?

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.

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.
