BS EN 13510:2000 – Earth-moving machinery Ð Roll-over protective structures Ð Laboratory tests and performance requirements Ð

This European Standard establishes a consistent and reproducible means of evaluating the load-carrying characteristics of Roll-Over Protective Structures (ROPS) under static loading,and prescribes performance requirements for a representative specimen under such loading.
It applies to the following seated design operator-controlled machines as defined in ISO 6165:
– dozers (crawler and wheeled);
– graders;
– loaders (crawler and wheeled);
– earth- and landfill compactors;
– skid-steer loaders and backhoe loaders;
– tractor portion (prime mover) of scrapers and articulated steer dumpers;
– rollers;
– rigid frame dumpers.
2 Normative references
This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies.
3 Definitions For the purposes of this European Standard, the following definitions apply.
3.1 Roll-over protective structure (ROPS): System of structural members whose primary purpose is to reduce the possibility of a seat-belted operator being crushed should the machine roll over. Structural members include any subframe, bracket, mounting, socket, bolt, pin, suspension or flexible shock absorber used to secure the system to the machine frame, but exclude mounting provisions that are integral with the machine frame.
3.2 Machine frame: Main chassis or main load-bearing member(s) of the machine which extend(s) over a major portion of the machine and upon which the ROPS is directly mounted.
3.3 Rollbar ROPS: One- or two-post ROPS without FOPS or any cantilevered load-carrying structural members.
3.4 Bedplate: Substantially rigid part of the test fixtures to which the machine frame is attached for the purpose of the test.
3.5 Deflection-limiting volume (DLV): Orthogonal approximation of a large, seated, male operator wearing normal clothing and a hard hat. (See ISO 3164:1992, figure 1.)
3.6 Representative specimen: ROPS, mounting hardware and machine frame (complete or partial) for test purposes that is within the manufacturer’s specifications.
3.7 Load distribution device: Device used to prevent localized penetration of the ROPS members at the load application point.
3.8 Load application point: Point on the ROPS structure where the test load is applied to the ROPS structure.
3.9 Deflection of ROPS: Movement of the ROPS structure caused by the application of the load and measured at the load application point.
3.10 Falling-object protective structure (FOPS): System of structural members arranged in such a way as to provide operators with reasonable protection from failing objects (for example, trees, rocks, small concrete blocks, tools).
3.11 Simulated ground plane (SGP): Flat surface on which a machine, after rolling over, is assumed to come to rest.
