1, the supplier shall in each case outside the box halogen-free materials posted "halogen-free products now vote" green label Attachment file (this same connection with ROHS control Halogen tester, by the purchaser to the supplier to perform, now unified ticket product offered by the company to the supplier). Warehouse receipts to be confirmed at the time of identification and halogen-free material on the case number of outsourcing, if the case of halogen-free materials, and stamped "HF" stamp on the delivery note. 2, IQC during testing, we must first check the tickets and now Goods item number, confirm whether the halogen-free materials, whether or not there is recognition by the Ministry of Development, etc., and then according to IQC incoming inspection process operations; IQC in submission environmental detection, Halogen-free material with ROHS material must be separately inspected, and halogen-free materials must be marked as halogen tester on a single submission, but to inform environmental inspectors. 3, after the completion of environmental testing, testing personnel must be stamped with "HF" chapter in the environmental testing record form, and then sent to the higher authorities to confirm whether the results meet the requirements of halogen-free. 4, where the halogen-free materials, IQC after the survey was completed, shall be stamped "HF" chapter in the inspection records. Adding halogens (fluorine, chlorine, bromine, iodine) in plastics and other polymer products to improve ignition, its advantages are: high flash point than ordinary polymer material, ignition at about 300 ℃. When burned, it will emit halogenated gases (fluorine, chlorine, bromine, iodine), rapid absorption of oxygen, so that the fire is out. But its drawback is the release of high concentrations of chlorine Shenzhen halogen tester, causing decreased visibility will lead to not recognize the escape route, while chlorine is highly toxic, affecting the respiratory system, in addition, the emissions of halogen-containing polymers halogen gas in combination with water vapor, generate corrosive gases (hydrogen halide), some of the equipment and buildings cause corrosion. PBB, PBDE, TBBPA and other brominated flame retardants are currently using more flame retardant, mainly used in electrical and electronic industry, comprising: a circuit board, computer, fuel cells, televisions and printers. These halogen-containing flame retardant material to produce dioxins when burned, and can exist in the environment for many years, even a lifetime accumulated in the organism, can not be discharged. Therefore, many international companies are actively promoting the complete abolition of halogen-containing materials in Dongguan halogen tester, such as prohibiting the use of halogenated flame retardants in their products and so on. At present, for halogen-free requirements, different products have different limits: If no halogenated wire and cable wherein the halogen indicators: All values ??halogen ≦ 50PPM (according to regulations PREN 14582); generating hydrogen halide content of post-combustion <100PPM ( According to regulations EN 5067-2-1); PH value of water soluble hydrogen halide produced after combustion ≧ 4.3 (slightly acidic) (according to regulations EN-5 0267-2-2); products after combustion in a sealed container Through beam of light transmittance rate ≧ 60% (according to regulations EN-50268-2). Halogen-free requirements: bromine, chlorine content of less than 900ppm, (bromine + chlorine) is less than 1500ppm.
