This International Standard specifies the characteristics required of attachments mounted on the front of commercial road vehicles and buses (as defined in ISO 3833) of maximum total authorized mass over 3,5 t (ISO-M08). The attachment permits the use of ropes, cables or bars, at the choice of the manufacturer, allowing the vehicle to be towed, or otherwise manoeuvred by other vehicles, or to be used for manoeuvring other vehicles. It excludes attachments for emergency operations, e.g. recovery of road vehicles after an accident. This International Standard does not apply to special purpose vehicles and standard vehicles used for special applications.
