Halogen-Free (HF) Testing

Halogen control requirements originated in the PCB industry and have gradually expanded to cover a wide range of products and materials. While halogen restrictions are not yet mandated by national law, they are commonly enforced across buyer-driven supply chains, particularly by international brands and industry associations.

Different industry standards and corporate specifications may impose varying halogen requirements. In most cases, whether halogens need to be restricted depends on the specific material, component, or final product, as outlined in buyer or company standards. "Halogen-Free" (HF), also referred to as "Low Smoke Halogen Free," does not mean a product contains absolutely no halogen compounds. In the electronics and electrical sector, a product is typically considered halogen-free if no intentional halogen-based compounds are added during production and if halogen content in the final product meets the threshold requirements.
