Overview
ISO/TS 24929-2:2025 - Child care articles - General safety - Part 2: Mechanical hazards (Technical Specification, first edition, Aug 2025) specifies requirements and guidance on mechanical hazards when developing safety standards for child care articles intended for children from birth to 48 months. The document defines general test conditions, safety philosophy and practical test methods to assess mechanical risks such as entrapment, moving parts, entanglement, choking and suffocation.
Key topics and technical requirements
The specification is organized to support standard writers, designers and test labs and includes:
-
General requirements and test conditions
- Tolerances for test equipment and defined test environments.
- Terms and definitions to ensure consistent interpretation.
-
Safety philosophy and accessibility
- Principles on how to evaluate whether hazards are accessible to infants and toddlers.
- Defined accessibility areas and product information expectations.
-
Entrapment hazards
- Assessment of head, neck, finger, limb, feet and hand entrapment.
- Probe philosophy and selection/use of probes for feet-first and head-first openings and irregular shapes.
- Specific test methodologies for different opening geometries.
-
Moving parts
- Hazards from shearing and crushing - requirements, test equipment and test methods.
-
Folding, locking and attachment systems
- Requirements to prevent unintended folding, release of locks, and failure under endurance and strength tests.
-
Entanglement hazards
- Snagging, cords/ribbons/ties and loop hazards with methods for loop and mass testing and related test equipment.
-
Choking hazards
- Assessment of small components, accessibility of filling materials and airway obstruction risks with defined test procedures.
-
Suffocation hazards
- Risks from plastic decals/sheeting and non-air-permeable packaging and methods to determine hazards.
Practical applications - who uses this standard
- Manufacturers and product designers - to design safer child care articles (for 0–48 months) and reduce mechanical hazards early in design.
- Test laboratories and conformity assessors - to apply consistent test methods, probe use and scoring for mechanical safety.
- Standards developers and regulators - to draft or harmonize national standards and certification criteria.
- Retailers and procurement teams - to verify product compliance before market introduction.
- Safety engineers and risk assessors - to perform hazard analyses and corrective action planning.
