scope:

This part of ISO 10542 specifies design requirements and performance requirements and associated test methods, for wheelchair tiedown and occupant-restraint systems (WTORS), as well as requirements for product marking and labelling and manufacturer' instructions and warnings to installers and consumers. It applies to all WTORS that use belt-type occupant restraints that are intended for occupied wheelchairs used as forward-facing seats by passengers and drivers of motor vehicles. This part of ISO 10542 applies to WTORS intended for use with all types of manual and powered wheelchairs, including three- and four-wheeled scooters, used by children and adults with a body mass equal to or greater than 22 kg. ISO 10542-1 applies primarily to complete WTORS, but portions of the standard can also be applied to components and subassemblies sold separately and for replacement parts.
