Specifies the test procedures and minimum performance criteria for evaluating roll-over protective structures fitted to tractors having a rear track width generally greater than 1150mm. It applies to driver-controlled tractors, but does not cover earth-moving equipment. It includes test procedures for both static and dynamic testing. A theoretical analysis of roll-over protective structures, which would provide equivalent performance to physical testing, is included.

This Standard specifies procedures for the evaluation of roll-over protective structures (ROPS) for the protection of drivers of tractors. It also sets out test procedures and minimum performance criteria for those structures.This Standard applies to driver-controlled tractors having a track width generally greater than 1150 mm and is not intended to apply to machinery whose primary purpose is earth-moving machinery as defined in AS 2294. The Standard describes two different methods of testing a ROPS. A dynamic test, which may be applied to tractors having a mass of not less than 800 kg and not greater than 6000 kg; and a static test, which may be applied to tractors having a mass of not less than 560 kg and not greater than 15 000 kg are described.The Standard does not apply to narrow-track tractors or high clearance tractors. Nor does it apply to certain forestry machines such as forwarders and other machines dealt with in other Standards.NOTE: A ROPS is a structure whose primary purpose is to reduce the possibility of an operator from being crushed or otherwise injured in the event of a tractor rolling over. Wearing a seat belt in conjunction with using a ROPS, may provide additional protection in the event of a tractor rolling over. Seat belts should comply with AS/NZS 2596 or SAEJ 386.
