The purpose of ROHS is to limit the use of harmful chemicals in electronic components, thereby reducing environmental pollution.Harmful chemicals, such as lead (Pb), mercury (Hg), cadmium (Cd), hexavalent chromium (Cr6+), polybrominated biphenyls (PBBs), polybrominated diphenyl ethers (PBDEs), bis(2-ethylhexyl) phthalate (DEHP), butyl benzyl phthalate (BBP), dibutyl phthalate (DBP), and diisobutyl phthalate (DIBP), can cause serious pollution and damage to soil, water, and air. The implementation of ROHS testing can effectively reduce the emission of harmful chemicals and protect the sustainable development of the environment.
