Rohs Compliance Testing

Sigma is ISO IEC 17025:2005 accredited ROHS Testing laboratory, equipped with sophisticated equipments like LC-ICPMS, GC-MSMS, spectroscopy to analyze and certify ROHS compliance testing in component materials through wet chemical screening, non-destructive analysis, XRF screening, and UV-vis.
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.
We are equipped with ultra modern technology and sophisticated instruments like LC-ICPMS, GC-MSMS, spectroscopy that can 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.
