Electronic Information Products Pollution Control Standards One very standard-setting process, specification, the second is open and transparent. The door is open standard group. According to reports Shui, 65 companies currently standard group members when it was founded by the first unit to today's 102 business units. Standard group of experts have repeatedly stressed that standards should be and international standards, and strive to "identical with." Enterprise "sit" China RoHS RoHS regulations restrict the use of the following hazardous substances: lead, cadmium, hexavalent chromium, mercury, polybrominated biphenyls (PBD) and polybrominated diphenyl ethers (PBDE). It contains a variety of elements in these substances. For example, lead to lower the melting point of the solder Shui wavelength chromatograph, improve workability. Lead can also be used as a cable insulating material vinyl heat stabilizer, cadmium have the same effect. Hexavalent chromium is typically used for anti-corrosion resilient plating. Chromium is also frequently used as a pigment colorant Shui direct reading spectrometer, and bromide compound is generally used as a flame retardant electronic equipment. XRF screening such technology can not assess whether the truly meet RoHS regulations. Able to correctly determine the chromium and bromine content above the limit does not mean that the product does not comply with RoHS regulations. But we should understand the constitution of these substances, and, with experienced analysis to make the right assessment.
