25、ndards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International or
26、ganizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules give
27、n in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 7
28、5 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 3471 was prepared by Technical Committee ISO/TC 127, Ear
29、th-moving machinery, Subcommittee SC 2, Safety requirements and human factors. This fourth edition cancels and replaces the third edition (ISO 3471:1994), which has been technically revised. It also incorporates the Amendment ISO 3471:1994/Amd 1:1997 and the Technical Corrigendum ISO 3471:1994/Cor 1
30、:2000. BS EN ISO 3471:2008ISO 3471:2008(E) ISO 2008 All rights reserved vIntroduction A review of the initial work on the criteria for roll-over protective structures (ROPS) indicated that these criteria were based on requirements for machines now identified as mid-range size machines. Since the ROP
31、S criteria were established, both smaller and larger machines have become common within the size range of earth-moving machines. The criteria are a combination of linear and exponential, with respect to mass. For small machines, the exponential criterion has been changed to a linear function with re
32、spect to machine mass. For larger machines, the exponential criterion was excessive at very large machine masses, and thus was changed to become a linear function with respect to machine mass. The longitudinal force criteria were added as new data became available. Situations could arise where ROPS
33、designs would meet the lateral and vertical loading requirements, but yet be considered as lacking sufficient performance capability in the longitudinal load direction. For this reason, this International Standard incorporates a ROPS longitudinal force criterion. The longitudinal force criterion has
34、 been established at 80 % of the lateral force requirement. The evaluation procedure will not necessarily duplicate structural deformations due to a given actual roll. However, specific requirements are derived from investigations on ROPS that have performed the intended function in a variety of act
35、ual roll-overs, as well as analytical considerations based upon the compatibility of ROPS and the machine frame to which it is attached.

36、Laboratory tests and performance requirements 1 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
37、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
38、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; roller; trencher. This International Standard is not applicable to t
39、raining 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 dir
40、ection 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 o
41、ther machines for a particular application. 2 Normative references The following referenced documents are indispensable for the application of this document.

49、15 away from the DLV. NOTE It is created by rotating a vertical plane parallel to the machines longitudinal centreline about a horizontal line through the outermost point of the upper ROPS member, to which the lateral load is applied (see Figure 6). The LSGP is established on an unloaded ROPS and moves with the member to which the load is applied while maintaining its 15 angle with respect to the vertical.
