RoHS (Restriction of Use of Hazardous Substances) regulations limit or ban specific substances—lead, cadmium, polybrominated biphenyl (PBB), mercury, hexavalent chromium, and polybrominated diphenyl ether (PBDE) flame retardants—in new electronic and electric equipment. RoHS Compliant means acting in full accordance with RoHS regulations and documenting testing for RoHS-controlled substances. Robertson carries an expansive selection of products that comply with RoHS standards. This information is noted on technical specification sheets, as well as indicated in the product data listed on www.robertsondirect.com, with a box that displays a 'check mark' and the RoHS logo.
