Q2: What are the regulatory standards for halogens?

The main regulatory limits for halogen free are as follows. Objective to limit the content of Cl and Br. To achieve the goal of eliminating the use of halogen flame retardant such as PVC. In order to reduce the environmental hazards released during the flame retardant process.

Standard Halogen limit
IEC-61249-2-21JPCA-ES-01-1999 Br<900ppm
Cl<900ppm
IPC-4101BJPCA-ES-01-2003 Cl+Br<1500ppm

Note: limit halogen flame retardant. It also directly affects whether the material can meet the requirements of flame retardant specifications (for example, UL-94)
