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 thecompliance 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 seatedoperator 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 anattachment.NOTE 2 It is expected that reasonable crush protection for a seat-belted operator will be provided under at least theconditions of an initial forward velocity of 0 km/h to 16 km/h on a hard clay surface of 30° maximum slope in the directionof 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 protectivestructures should it be decided to provide such protection for these or other machines for a particular application.
