Halogenated materials and their environmental impact are becoming a major concern for several non-governmental organizations (NGOs) and consumers. The electrical and electronic equipment (EEE) industry is trying to address these concerns by voluntarily developing reliable and cost-effective alternatives, especially ‘low halogen’ materials.

Halogens are a group of chemically related substances that create salts when they react with metals. The principal halogens used in EEE are fluorine (F), chlorine (Cl), bromine (Br), and iodine (I). They can be contained in polymers and other organic materials – specifically polyvinyl chloride (PVC) and brominated flame retardants (BFRs). These are used in a variety of EEE, especially when flammability resistance is a key characteristic.

The EEE is hoping to answer the concerns of NGOs and consumers with the use of ‘low halogen’ materials, but the term isn’t clearly defined and understood around the globe. For manufacturers hoping to gain a better understand of ‘low halogen’ a good place to start is the International Electronics Manufacturing Initiative (iNEMI) definition:

  • All printed board (PB) and substrate laminates shall meet Br and Cl requirements for low halogen as defined in IEC 61249-2-21 and IPC-4101B:
    • Chlorine (Cl) < 900 ppm
    • Bromine (Br) < 900 ppm
    • Cl and Br combined < 1,500 ppm
  • For components other than printed board and substrate laminates, each plastic within the component should contain:
    • Chlorine (Cl) < 1,000 ppm (if the Cl source is from Chlorinated Flame Retardants (CFRs) or PVC or PVC copolymers)
    • Bromine (Br) < 1,000 ppm (if the Br source is from Brominated Flame Retardants (BFRs))

Manufacturers planning to use ‘low halogen’ materials in their EEE products should look to work with a third-party service provider capable of examining both homogenous materials and complex products to the correct limits.

SGS Luminaires Services

SGS offers halogen testing for both homogenous materials and complex products with a medium detection limit of 50 ppm for each halogen (F, Cl, Br, I) with reference to EN 14582. They also provide a range of other services to EEE and luminaire manufacturers that enable them to gain full access to global markets. Backed by a worldwide network of state-of-the-art laboratories, SGS is the first choice for stakeholders looking to meet and exceed their goals. Learn more about SGS Luminaires Services.
