AS/NZS 10542.1:2015

[Current]

Adopts ISO10542-1:2012 to specify design and performance requirements and associated test methods for wheelchair tiedown and occupant-restraint systems (WTORS), product marking and labelling, and manufacturers’ instructions and warnings to installers and consumers. It is applicable 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.
