What is the halogen content in the wire rod to meet the standard?

Bromine flame retardants are the most widely used: most of them decompose at 200℃~300℃. In the process of decomposition, the free radicals produced by the degradation reaction of polymer materials are captured, and the chain reaction of combustion is delayed or terminated. The released HBr is a kind of refractory gas, which can cover the surface of the material and block the combustible gas on the surface. Bromine flame retardants are widely used and are one of the largest organic flame retardants in the world. The main products are decabromodiphenyl ether, tetrabromobisphenol A, pentabromotoluene and hexabromocyclododecane.

Different products may have different definitions of halogen-free requirements. The 50PPM upstairs seems to be a wire or something. For the definition of halogen-free copper clad laminate, refer to the requirements of JPCA-ES-02 in Japan: when tested according to JPCA-ES-0 1, the contents of chlorine and bromine are less than 0.09% (mass), that is, 900PPM respectively. IEC and IPC have not officially released the standards in this field, but it is said that the forthcoming IPC-4 10 1C may have four pages about halogen-free.

I wonder if what you said has anything to do with this.
