Ministry of Information Industry Electronic Information Products Pollution Control Standards Working Group, told reporters Deputy head of HJ heavy metals, Ministry of Information Industry as early as in 2004, started the electronic information products pollution control standards development work, the general idea is: active track and participate in international standards; complete the drafting of electrical and electronic products hazardous substances monitoring standard tasks entrusted to the National Standards Committee; development of electronic information products pollution control industry standards. Currently, the standard group has actively participated in the ITU (IEC) of TC111 organizational activities, coordination and arrangement according to the National Standards Committee, the lead organization of the Chinese working group WG3; also set up electrical and electronic products measuring the concentration of hazardous substances in the work program of national standards Group; October 2004 to complete the formation of the Electronic Information Products Pollution Control Standards Working Group food industry heavy metal detector, began a limited standard electronic information products for hazardous substances, testing standards, lead-free soldering standards, certification and labeling standards 8 industry standards work. ROHS XRF system gives lower accuracy in the value of the case is important heavy metal detector, we must be careful. When using XRF systems, measurement errors often reach as high as ± 30% ± 50%. Such a large error, partly due to the depth, beam size, spectral interference, crosstalk penetration, lack of comparable standard, uniform surface area is not large enough. Test method must be changed (FIG. 2) when needed for accurate measurement. Table 1 shows the levels of regulated substances can be used to assess several test methods. What is the meaning of test results? Shui Hua Wei _ Heavy Metal Detector (Online) _ heavy metal provided by the Dongguan City Ding Sheng Precision Instrument Company.
