    • RoHS Compliance Testing

RoHS Compliance Testing has become standard procedure for most manufacturers, sellers, distributors and recyclers of electrical and electronic components or equipment sold or used in the European Union. The need for RoHS testing is a result of the Restriction of Hazardous Substances Directive or RoHS Directive, which became effective on July 1, 2006. The Directive was drawn up in the European Union to protect human health and the environment from hazardous substances by restricting the use of six hazardous chemicals in electrical and electronic products.

State of art chemistry Lab and Metallurgy Lab at Sigma Test & Research Centre equipped with ultra modern technology and sophisticated instruments like LC-ICPMS, GC-MSMS, spectroscopy, etccan determine the level of the following first four substances restricted by RoHS in component material:

Mercury (Hg): 100ppm

Hexavalent Chromium (Cr(VI)): 1000 ppm

Cadmium (Cd): 100ppm

Polybrominated Biphenyls (PBB): 1000 ppm

Lead (Pb) : 1000ppm

PolybrominatedDiphenyl Ethers (PBDE): 1000 ppm

RoHS has set maximum concentration values for each of these restricted substances. All values are set at 0.1%, except for cadmium with a limit of 0.01%. STRC has the capabilities to test for lead, mercury, cadmium and hexavalent chromium. RoHS compliance testing is performed in our lab using spectroscopy and wet chemistry methods to determine the concentrations of these RoHS substances in test samples. All RoHS testing results are fully documented in Certified Test Reports for our customers’ records.

RoHS and the recast directive RoHS2 that went into effect in July 2011 do exempt a number of materials and products from the requirements set forth in the Directive and include additional restrictions that went into effect on December 31, 2011.
