Halogen Free Statement

Halogen-Free Position Statement
Bel Fuse defines a “low-halogen” or “halogen-free” device per the iNEMI definition as indicated
below. This position statement defines maximum PPM of bromine (Br) and chlorine (Cl) to be
considered “BFR/CFR/PVC-free or halogen-free “ when used in flame retardants and PVC in
electronic components and assemblies.
A device must meet all of the following requirements to be considered halogen-free:
1) All printed board and substrate laminates shall meet Br and Cl requirements for low
halogens as defined in IEC 61249-2-21:
900 PPM maximum chlorine
900 PPM maximum bromine
1500 PPM maximum total
and IPC-4101B per 1a) below.
1a) Non-halogenated epoxide with a glass transition temperature of 120°C minimum.
The maximum total halogens contained in the resin plus reinforcement matrix is 1500
PPM with a maximum chlorine of 900 PPM and maximum bromine of 900 PPM.
2) For components other than printed board and substrate laminates:
Each plastic within the component must contain < 1000 PPM (0.1%) of bromine if the Br
source is from BFRs and < 1000 PPM (0.1%) of chlorine if the Cl source is from CFRs or
PVC or PVC copolymers.
Plastic is defined as any of a group of synthetic or natural organic compounds produced by
polymerization, optionally combined with additives (organic or inorganic fillers, modifiers, etc.)
into a homogeneous material capable of being molded, extruded, coated, printed or cast into
various shapes and films.
PVC copolymer: Copolymers are polymers derived from two or more monomers. Highly
chlorinated PVC copolymers, block polymers, and congeners are not considered acceptable
alternatives to PVC for low-halogen components.
Although the halogens fluorine (F) and iodine (I) may be present in some
electronics, they are not included in this position statement. The halogen astatine
(At) is also excluded as it is radioactive and has no functional use in electronics. Additionally,
materials used in process (such as soldering fluxes), product delivery systems, and packaging
are not considered within the scope of this definition.
