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).
BSI recommends this version of standard for organisations operating in or with the UK. The ISO edition is available here if required.
