RoHS Compliance and Halogens

Question: If my product is compliant with the Restriction of Hazardous Substances (RoHS) recast, is it also compliant with halogen presence standards?

Answer: No. Compliance with RoHS does not cover compliance with all the halogen-related standards.

Polybrominated biphenyl flame retardants (PBB) and polybrominated diphenyl ethers (PBDE) are the only halogenated substances restricted under RoHS.

Additional halogen-related standards include:

IEC 61249-2-21:2003

  • Covers only printed circuit boards — Materials for printed boards and other interconnecting structures — Part 2-21: Reinforced base materials, clad and unclad — Non-halogenated epoxide woven e-glass reinforced laminated sheets of defined flammability (vertical burning test), copper-clad.
  • Halogen free printed circuit board:
    • Max total halogens: 1,500 ppm.
    • Max bromine: 900 ppm.
    • Max chlorine: 900 ppm.

IPC: IPC/JEDEC J-STD-709  

  • Covers everything else used in electronic products.
  • Each material within an electronic product (excluding printed board laminates) shall contain <1,000 ppm (0.1 percent) by weight of bromine if the bromine source is from BFRs, and <1,000 ppm (0.1 percent) by weight of chlorine if the chlorine source is from CFRs, PVC, PVC congeners, PVC block polymers, PVC copolymers, or polymer alloys containing PVC.
  • Higher concentrations of bromine and chlorine are allowed in plastics contained within electronic products (other than printed board laminates contained within those devices) as long as their sources are not flame retardants, PVC, PVC congeners, PVC block polymers, PVC copolymers, or polymer alloys containing PVC.
