ISO 29061-4:2017

ISO 29061-4:2017 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. ISO 29061-4:2017 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. ISO 29061-4:2017 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. NOTE Booster system usability evaluation, including securing of a child in the booster system, is covered by ISO 29061-5.
