RoHS (Restriction of Use of Hazardous Substances) regulations are designed to eliminate some of the particular chemical substances that can be dangerous to the environment and human health. Mercury (Hg), Lead (Pb), Cadmium (Cd), Hexavalent chromium (Hex-Cr), Polybrominated biphenyl (PBB) and Polybrominated diphenyl ether (PBDE) are the hazardous substances that are restricted in the manufacture of electronics and electronic devices, automatic dispensers, light bulbs, LED, household equipments, telecommunication equipments, toys and sports equipments . If appears, create environmental pollution and can be dangerous to the exposed manufacturer employees and recyclers. RoHS regulations were fully implemented in the Europe and UK in the year 2006.
It is very important for the manufacturer to learn and to educate themselves about RoHS. Its testing should be carefully implemented as these hazardous chemical elements cause many serious ailments like different types of cancers. Hence, it is the responsibility of manufactures, importers, exporters and retailers for ensuring their products do not go beyond the maximum concentration limits. The maximum concentration limit for Cadmium is 0.01% generally found in semiconductors, PVC stabilizers, batteries, paints, dyes, solders and coatings. Lead, is often used in solders, termination coatings, PVC stabilizers, batteries, paints and pigments, Mercury generally used in sensors, batteries, fluorescent lamps and relays, Hexavalent Chromium often found in anti-corrosive coatings and in some of the plastics, Polybrominated biphenyls and Polybrominated diphenyl ethers are generally used as flame retardant are also have a maximum limit of 0.1%.
There are laboratories that offered RoHs testing. Handheld XRF analyzers are the portable devices that can be used for instant testing and documentation. Testing through these devices is fast, non-invasive and cost-effective. It also reduces the chances of human error.
WEEE (Waste from Electrical and Electronic Equipment) is a directive that controls the handling as well as recycling of electric and electronic equipments or devices.
Spectro Analytical Lab offers all the facilities such as AAS, XRF and ICP instruments for carrying out RoHS testing and it also provides training and assistance in this regard.
