1 Scope This document provides criteria for judgement of usability of child restraint systems (CRS) with regard to the securing of a child in the child seat and other daily handling aspects. 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.
