Road vehicles — Methods and criteria for usability evaluation of child restraint systems and their interface with vehicle anchorage systems Part 5: Installation and securing of child in a booster system (Edition 2, 2026)

Abstract
This document provides criteria for judgement of usability of booster seat child restraint systems (CRSs) when installing them and securing a child.

This document provides criteria for judgement of:

ease of availability of instructions;
clarity of instruction manual and labelling; and
ease of use of design related features of the CRS related to the installation in a vehicle.
The procedure can also be used for evaluation of vehicle integrated booster systems.

NOTE 1 CRS includes enhanced child restraint systems (ECRS) according to UN Regulation No. 129.

NOTE 2 Although ISOFIX is defined in the original “ISOFIX” standard (ISO 13216-1) to be a rigid system, the term “ISOFIX” in this document is extended to include flexible CRS attachments (e.g. LATCH in USA, UAS in Canada).
