Halogen-free definition and standard

JPCA-ES-01

  * Cl＜0.09wt%（900ppm）

  * Br＜0.09 wt%（900ppm）

  * Br+Cl＜0.15wt%（1500ppm）

IEC 61249-2-21 

* 900 ppm maximum Cl

* 900 ppm maximum Br

* 1500 ppm maximum total halogens

IPC-4101B

* 900 ppm maximum Cl

* 900 ppm maximum Br

* 1500 ppm maximum total halogens

All PCB laminates must meet Br and Cl requirements for low halogen as defined in IPC-4101B。

 

For components other than PCB laminates, all homogeneous materials must contain less than 900ppm of Bromine [if the Bromine(Br) source is from BFRS] and less than 900ppm of Chlorine [if the Chlorine(Cl) source is from CFRS or PVC or OVC congeners]. Higher concentrations of Br and Cl are allowed in homogenous materials of components other than PCB laminates as long as their sources are not BFRs, CFRs, PVC or PVC congeners.

 

So，communication and MSDS is necessary  between customs and suppliers。
