The halogens include Fluorine(F), Chlorine(Cl), Bromine(Br), Iodine(I) and Astatine(At) which exists in the VIIA clan of Chem.-Physics Periodic table. Astatine(At) is the artificial radioactive element. The Halogen which is pointed out in electronics industry and chemical testing is F, Cl, Br, I. Halogen compounds as flame retardant have been available for electronic parts &material, products casing and plastics. Such kinds of flame retardant can’t recycle. What’s worse, in the progress of burning and heating, it will release some hazardous substances, which will cause continuous environmental

Halogen IEC-61249-2-21
Limitation: Halogens, non-metal elements include Fluorine, Chlorine, Bromine, Iodine, and Astatine, the maximum concentration can't not excess 1500PPM
Reason: Halogenated plastic materials will release corrosive and toxic gases if ignited in a fire. The corrosive element(i.e. Chlorine) of these gases has the risk to damage electronics function. The toxic element may also affect human immune and endocrine system. Toxicity study has also classified these toxic elements are potentially carcinogenic, heterogenic risk in human.
