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 non-governmental, in liaison with sO, also take part in the work. IsO collaborates closely with the International Standards are drafted in accordance with the rules given in the ISO/lEC 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 75 % of the member bodies casting a vote. rights.

ISO 3449 was prepared by Technical Committee ISO/TC 127, Earth-moving machinery, Subcommittee SC 2, Safety requirements and human factors. This fifth edition cancels and replaces the fourth edition (IsO 3449:1992), which has been technically revised. iv Iso2005-Allrightsreservec ISO3449:2005(E) Introduction This International Standard provides performance criteria for falling-object protective structures (FOPS). It conditions. It is intended to assure operators of reasonable protection from falling objects of different sizes and masses Its laboratory tests are a means of evaluating the characteristics of the structures used to protect the operator resist impact loading. This International Standard establishes a consistent, repeatable means of evaluating characteristics of FOPS under loading and prescribes performance requirements for these structures under such loading in a representative test. For similar tests on FOPs for excavators and excavator-based machines, see IsO 10262 @ ISO 2005 - All rights reserved ISO 3449:2005(E) INTERNATIONALSTANDARD Earth-moving machinery Falling-object protective structures Laboratory tests and performance requirements Scope 1 This International Standard specifies laboratory tests for measuring the structural characteristics of, and gives performance requirements in a representative test for, falling-object protective structures (FOPs) intended for use on ride-on earth-moving machines as defined in ISO 6165. It is applicable to both FOPS supplied as an integral part of the machine and those supplied separately for attachment to the machine. It is not intended to apply to FOPs intended for use on landfill compactors, excavators, rollers, trenchers, pipelayers, for the oflessthan15kW. NOTE This International Standard can be used to provide guidance to the manufacturers of roll-over or falling-object protective structures should itbedecidedtoprovide suchprotectionfortheseorothermachinesfora particularapplication. 2 Normative references The following referenced documents are indispensable for the application of this document.
