The document provides criteria for judgement of:
-
— ease of availability of instructions;
-
— clarity of instruction manual and labelling; and
-
— the ease of use of design related features of the CRS related to securing the child or child dummy in a CRS installed in vehicle.
This document can be used in conjunction with either ISO 29061‑1 or ISO 29061‑3 for making a complete usability evaluation of child restraint systems attached to the vehicle with ISOFIX/LATCH or vehicle seat belts.
