Mobility Aid Securement and Occupant Restraint (MASOR) Systems for Motor Vehicles

1.1 This Standard specifies (a) general design requirements; (b) performance requirements; (c) test methods; (d) requirements for product marking and labelling; and (e) requirements for instructions and warnings for MASOR systems intended for use with forward-facing mobility aids occupied by children and adults with mass of 22 kg or greater, travelling in personally licensed and public motor vehicles having a gross vehicle weight rating (GVWR) of less than 7000 kg (15 500 lb).

1.2 The requirements of this Standard apply to MASOR systems that use all types of mobility aid securement systems, including four-point strap-type systems, as well as docking and clamping devices.

1.3 This Standard places particular emphasis on the requirements for the dynamic performance of MASOR systems in a 48 km/h (30 mph), 20 g frontal impact and does not determine suitability for side or rear vehicle impact, or impacts of lesser or higher magnitude. It also specifies test procedures and performance requirements regarding (a) webbing slippage at adjustment devices for strap-type securement systems; and (b) partial but ineffective engagement of restraints and their components that could be perceived to be effectively engaged.

1.4 While the primary focus of this Standard is MASOR systems that are packaged by the manufacturer as a complete system, manufacturers of MASOR systems components and subassemblies may certify their equipment as being in compliance with this Standard provided that (a) the subassemblies and components intended to be used together to create a MASOR system meet all the appropriate requirements of this Standard; and (b) the separately sold components and subassemblies are provided with instructions in accordance with Clause 4.6, where the word .compatible. means tested together to comply with this Standard.

1.5 The values given in SI (metric) are the standard. The values given in parentheses are for information only.
