RoHS stands for Reduction of Hazardous Substances

RoHS stands for Reduction of Hazardous Substances and is an EU directive that prevents the use of certain substances in electronic products. It essentially directs to not keep certain chemicals in the product. The directive is popularly known as the “Lead Directive” among the engineers but in reality its not bound only with the lead but has rules for certain other chemicals as well.  The list of chemicals on which this regulation works are as follows: Lead (Pb) Mercury (Hg) Cadmium (Cd) Hexavalent Chromium (Cr6+) Polybrominated Biphenyls (PBB) Polybrominated Diphenyl Ethers (PBDE) Bis(2-Ethylhexyl)phthalate (DEHP) Benzyl butyl phthalate (BBP) Dibutyl phthalate (DBP) Diisobutyl phthalate (DIBP) All follow the limitation of a maximum of 0.1% The directive has been taken to be much more than only Lead Directive as for some electronic industries the product without Lead stays to be RoHS Complaint in nature. However, not all chemicals in the list are RoHS Complaint in nature. LDR or Light
