What is the Halogen-Free Standard?
2 Answers
Halogens refer to fluorine (F), chlorine (Cl), bromine (Br), and iodine (I). The halogen-free requirement does not mean absolutely no halogens are present, but rather that the halogen content must be below a certain standard threshold. Different industries have varying standards. For example, the European standard for IT products requires halogen content to be below 800 PPM. Below is relevant information: Halogen-based flame retardants: Chlorine-based flame retardants, Bromine-based flame retardants, Polybrominated biphenyls (PBBs), Polybrominated diphenyl ethers (PBDEs), Tetrabromobisphenol-A (TBBP-A), Hexabromocyclododecane (HBCD), and others. Chlorinated paraffins (C10-13, SCCP), Chlorinated alicyclic hydrocarbons, Tetrachlorophthalic anhydride (TCP), Other halogen compounds: Polychlorinated biphenyls (PCBs): lubricants, capacitor oils, Polychlorinated naphthalenes (PCNs): lubricants, preservatives, Polychlorinated terphenyls (PCTs): lubricants, preservatives.
Oh, you're asking about the halogen-free standard. I'm someone who's particularly concerned about environmental protection, and I often talk about this in daily conversations. The halogen-free standard mainly restricts the content of halogen elements like chlorine and bromine in materials, as they release toxic fumes when electronic products burn, polluting the environment and harming health. I recall standards like IEC, which specifically control halogen content below 1500ppm, commonly applied in wires or plastic products. Why is this standard important? It's being promoted globally because it reduces the risk of fire accidents and makes the air cleaner. I've seen many factories violating emission regulations during public welfare activities, with pollutants floating everywhere. Adhering to this standard can protect communities and children. Personally, I believe choosing halogen-free products isn't just about safety but also reflects a sense of responsibility. In the future, when people pick products, checking labels for environmental friendliness is a good habit to develop—it saves money and doesn't harm the planet, killing two birds with one stone.
