ISO 29061-5:2026

Overview

ISO 29061-5:2026 specifies internationally recognized methods and criteria for the usability evaluation of booster seat child restraint systems (CRSs) and their interface with vehicle anchorage systems. This standard provides a structured approach to judge the ease and clarity of installing booster systems and safely securing a child in these systems, whether the CRS is standalone, integrated into the vehicle, or uses flexible or rigid attachment systems such as ISOFIX, LATCH, or UAS. The focus is on boosting correct usage and enhancing child safety by ensuring clear instructions, effective labeling, and user-friendly design features.

Key Topics

• Usability Criteria: ISO 29061-5:2026 establishes clear criteria for evaluating:
  • Access and clarity of installation instructions (manuals, labels, videos)
  • Design-related features that impact installation and use
  • Ease of securing the child in the booster system
• Assessment Procedure: The standard describes a repeatable evaluation procedure, covering:
  • Separate assessment of the booster system
  • Usability during installation in vehicle seating positions
  • Procedures for correctly securing a child
• Scoring and Evaluation:
  • Items are rated as good, average, or poor and weighed by importance
  • Final results are represented as a percentage, supporting meaningful comparisons among products and configurations
• Inclusion of Enhanced and Integrated Systems: The document covers enhanced child restraint systems (ECRS as per UN Regulation No. 129) and integrated booster seats, as well as both rigid and flexible attachment interfaces.
• Consumer and Industry Benefits:
  • Encourages improved design for easy and correct CRS use
  • Provides transparency for manufacturers and valuable information for parents, caregivers, and vehicle designers

Applications

ISO 29061-5:2026 is relevant for a range of stakeholders in the automotive, child safety, and consumer goods industries:

• Child Restraint System Manufacturers: Use the standard to design, test, and enhance the usability of booster seats and integrated CRS, ensuring compliance and supporting product development.
• Vehicle Manufacturers: Assess compatibility and usability of seating positions and anchorage systems for booster seats, including integrated solutions.
• Certification and Regulatory Bodies: Apply the methods and criteria for quality assurance, certification, and market surveillance efforts related to child occupant safety.
• Consumer Organizations and Testing Labs: Adopt a standardized usability evaluation tool to inform car seat ratings and guides, helping parents and guardians choose safe, easy-to-use booster systems.
• Parents and Caregivers: Benefit from clearer information and better-designed products, improving the correct use of booster seats and securing children safely.

Related Standards

ISO 29061-5:2026 is part of a broader framework for child restraint system usability and safety. Key related standards include:

• ISO 13216-1: Road vehicles - Anchorages for child restraint systems (ISOFIX/LATCH/UAS basics)
• ISO 13216-2: Road vehicles - Top tether anchorages and attachments for child restraint systems
• ISO 13215-2: Risk reduction of CRS misuse - Correct installation requirements and procedures
• ISO 13215-3: Prediction and assessment of misuse of child restraint systems
• UN Regulation No. 129: Enhanced child restraint systems (ECRS) requirements

Practical Value

The application of ISO 29061-5:2026 improves child occupant protection by:

• Enhancing ease-of-use in real-world settings
• Reducing the risk of incorrect booster seat installation and use
• Providing a basis for regulatory consistency and consumer product comparison
• Supporting innovation in booster seat and vehicle integration, while maintaining global safety standards

Adopting this standard benefits manufacturers, regulators, and consumers alike, advancing child safety in every journey.
