ISO/TS 24929-4:2026 PDF

Overview

ISO/TS 24929-4:2026 is a technical specification developed by the International Organization for Standardization (ISO) focused on child care articles and their general safety requirements related to thermal hazards. This standard provides essential guidance for those involved in drafting safety standards, manufacturing, or evaluating products used for child care. Its focus is on mitigating risks associated with hot and cold surfaces, flammability, extreme temperatures, and other related thermal hazards to ensure the highest level of protection for children.

Key Topics

ISO/TS 24929-4:2026 addresses several critical areas concerning safety from thermal hazards in child care articles:

• Flammability and Burning Hazards: The standard outlines requirements for flame spread and ignition resistance, referencing ISO 8124-2:2023. Materials that can easily ignite or propagate flames, or produce flaming debris and surface flash, are considered unacceptable for child care articles.
  • Emphasis is placed on avoiding the use of chemical flame retardants due to possible chemical hazards.
  • Specific materials such as celluloid and materials with pile surfaces prone to surface flash are discouraged.
• Hot and Cold Surfaces: The specification recognizes the risk of burns or injuries due to contact with surfaces that are too hot or too cold, noting children’s limited ability to respond quickly to temperature extremes.
• Hazards from Hot and Cold Liquids or Food: Risks associated with scalds from hot liquids or food are covered, with a requirement for clear warnings in product information where such hazards exist.
• Hazards from Contact with Flames: Products designed to shield children from open flames must provide adequate protection, preventing any contact.
• Hyperthermia and Hypothermia: The document points out dangers linked with overheating (hyperthermia) and overcooling (hypothermia), including the increased risk of sudden infant death syndrome (SIDS) for children under 12 months due to overheating.

Applications

The practical applications of ISO/TS 24929-4:2026 extend across the entire child care product industry, including:

• Product Development: Designers and manufacturers can use this specification to ensure that materials, construction, and instructions for use minimize thermal hazards.
• Safety Assessment: Testing laboratories and safety assessors reference these guidelines to evaluate compliance and improve product safety profiles.
• Regulatory Compliance: Governments and agencies may incorporate this standard into legislation or guidelines governing the sale and use of child care products, helping reduce thermal-related injuries among children.
• Consumer Information: The specification mandates clear warnings and instructions for consumers, enhancing caregiver awareness of potential risks associated with thermal hazards in child care articles.

Related Standards

Several international standards are referenced or aligned with ISO/TS 24929-4:2026, providing a comprehensive framework for child care product safety:

• ISO 8124-2:2023 - Safety of toys – Part 2: Flammability: Provides key test methods and safety limits regarding materials' flammability.
• ISO 13732-1 - Ergonomics of the thermal environment – Methods for the assessment of human responses to contact with surfaces – Part 1: Hot surfaces: Offers guidance on maximum allowable temperatures for surface contact.
• IEC Guide 117 - Electrotechnical equipment – Temperatures of touchable hot surfaces: Recommends safe temperature limits and testing approaches for accessible surfaces.
• ISO/TS 24929-1 - Child care articles – General safety – Part 1: Contains overarching safety principles that are meant to be used in conjunction with this part of the series.

Adhering to ISO/TS 24929-4:2026 enhances trust in child care article safety and supports a safer environment for young children by systematically addressing thermal hazards. The standard is a crucial resource for regulators, manufacturers, product designers, and safety professionals seeking to minimize risk and ensure compliance with international best practices.
