IEC PAS 63015:2016(E) provides terms and definitions for "low-halogen" electronic products that have the potential to contain the halogens bromine (Br) and chlorine (Cl) from the use of BFRs, CFRs, and PVC, and recommends methods for marking and labeling. This standard may be applied to all nonmetallic and nonceramic materials within electronic products. It establishes the maximum concentration level for the halogens bromine (Br) and chlorine (Cl) from the use of BFRs, CFRs, and PVC. While the halogen group contains fluorine, chlorine, bromine, iodine, and astatine, this document will use the term "low-halogen" to refer only to bromine and chlorine. Refer to Annex C for further explanation for exclusion of astatine, iodine and fluorine.
