Scope

This International Standard specifies performance requirements for metallic roll-over protective structures (ROPS) for earth-moving machinery, as well as a consistent and reproducible means of evaluating the compliance with these requirements by laboratory testing using static loading on a representative specimen. NOTE 1 The structure can also provide FOPS (falling-object protective structure) protection. This International Standard is applicable to ROPS intended for the following mobile machines with seated operator as defined in ISO 6165 and with a mass greater than or equal to 700 kg: -- dozer; -- loader; -- backhoe loader; -- dumper; -- pipelayer; -- tractor section (prime mover) of a combination machine (e.g. tractor scraper, articulated frame dumper); -- grader; -- landfill compactor; -- miler; -- trencher. This International Standard is not applicable to training seats or additional seats for operation of an attachment. NOTE 2 It is expected that reasonable crush protection for a seat-belted operator will be provided under at least the conditions of an initial forward velocity of 0 km/h to 16 km/h on a hard clay surface of 30° maximum slope in the direction of roll, and 360~ of roll about the longitudinal axis of the machine without loss of contact with the slope. NOTE 3 This International Standard can be used to provide guidance to the manufacturers of roll-over protective structures should it be decided to provide such protection for these or other machines for a particular application.
