IEC GUIDE 122:2024 raises awareness and provides recommendation on the use of consistent terminology related to halogen content for use in horizontal and product-specific IEC standards. The terminology related to halogen content provided in this Guide does not take into consideration astatine (At) and the artificially created tennessine (Ts), since they are not used in electrical and electronic equipment (EEE). Diatomic halogen molecules (F2, Cl2, Br2, I2), normally not found in EEE, are also excluded from the terminology recommended in this Guide.

Overview

IEC GUIDE 122:2024 - Guide for Defining Halogen Content Terminology in IEC Standards provides recommendations for the consistent use of halogen content terminology across IEC standards. Halogens, particularly fluorine, chlorine, bromine, and iodine, are often found in electrical and electronic equipment (EEE), sometimes purposefully added to enhance specific properties or inherently present due to environmental or manufacturing factors. However, inconsistent terminology and thresholds in existing standards have led to confusion and misunderstandings for manufacturers, regulators, and users. IEC GUIDE 122:2024 aims to address these challenges, promoting uniform, scientifically sound, and verifiable terminology for halogen content.

Key Topics

Scope of Halogen Content Terminology: The Guide clarifies that it applies only to fluorine (F), chlorine (Cl), bromine (Br), and iodine (I) in the context of EEE. Astatine (At), tennessine (Ts), and diatomic halogen molecules (e.g., F₂, Cl₂, Br₂, I₂) are excluded as they are not relevant to electrical and electronic equipment.

Common Terms and Definitions: The document reviews terms such as halogen-free, non-halogenated, zero-halogen, low-halogen, halogenated, and variations like non-chlorine or non-bromine. These terms may refer to different combinations of halogens and different maximum content thresholds, depending on the standard or product sector.

Confusion in Industry and Standards: Inconsistent use of terminology can result in misinterpretation, hinder environmental and safety compliance, and even lead to "greenwashing"-where environmental claims are overstated.

Recommendations for Harmonization: The Guide proposes best practices for using halogen-related terminology, emphasizing clear definitions, context-specific usage, and scientifically determined content thresholds. Committees are advised to specify which halogens are covered, the methods of determination, and the relevant limits. Where possible, terms should be aligned with those defined in this Guide to avoid ambiguity.

Applications

Standardization Development: IEC technical committees and product standards developers use IEC GUIDE 122:2024 when drafting new or revising existing standards that reference halogen content. It ensures that terminology is consistent, reducing confusion and aiding harmonized implementation globally.

Product Compliance and Communication: Manufacturers, suppliers, and certification bodies use harmonized halogen content terminology when declaring product characteristics, facilitating clarity in supply chains and regulatory compliance, particularly in sectors concerned with fire safety, environmental protection, and hazardous substance restrictions.

Environmental and Health Considerations: Consistent language regarding halogenated substances helps to communicate environmental and health impacts effectively, such as fire risks or toxic emissions related to halogen content.

Support for Legislation and Market Claims: Clear terminology enables accurate product labelling and supports conformity with environmental directives and voluntary ecolabels, thereby promoting trust and transparency for end-users and regulatory authorities.

Related Standards

IEC GUIDE 122:2024 complements and interacts with several other International Electrotechnical Commission and standards bodies’ documents, including:

IEC Guide 109: Principles for specifying environmental aspects in IEC standards.

IEC 61249-2 Series: Specifies halogen content requirements for base materials used in printed circuit boards.

IEC 62821, IEC 60502, IEC 60092: Standards related to cables, including requirements for "halogen-free" materials.

UL 746E, JPCA-ES01, JEDEC/ECA JS709C: International and national standards defining specific halogen thresholds for various materials and applications.

IEC Electropedia and ISO Online Browsing Platform: Authoritative references for standardized terminology.

By following the guidance in IEC GUIDE 122:2024, all stakeholders in the electrical and electronic sector can achieve greater clarity, safety, and environmental stewardship in the use and communication of halogen content in products and standards.
