25、. 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 organizations, governmental and non
26、-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 given in the ISO/IEC Directives, Part
27、 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
28、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 3449 was prepared by Technical Committee ISO/TC 127, Earth-moving machinery, Subcommittee

30、alling-object protective structures (FOPS). It recognizes that there are various classes and sizes of machines that operate in a variety of environmental conditions. It is intended to assure operators of reasonable protection from falling objects of different sizes and masses. Its laboratory tests a
31、re a means of evaluating the characteristics of the structures used to protect the operator from localized impact penetration and, indirectly, of the load-carrying capacity of the supporting structure to resist impact loading. This International Standard establishes a consistent, repeatable means of
32、 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. BS EN ISO 3449:2008BS EN ISO 3449:2008INTERNATIONAL STANDA

34、ts 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 inte
35、nded to apply to FOPS intended for use on landfill compactors, excavators, rollers, trenchers, pipelayers, for the additional seat for operation of an attachment (e.g. attachment backhoe), or on machines with a power rating of less than 15 kW. NOTE This International Standard can be used to provide
36、guidance to the manufacturers of roll-over or falling-object protective structures should it be decided to provide such protection for these or other machines for a particular application. 2 Normative references The following referenced documents are indispensable for the application of this documen

40、nitions For the purposes of this document, the following terms and definitions apply. 3.1 falling-object protective structure FOPS system of structural members arranged in such a way as to provide operators with reasonable protection from falling objects (trees, rocks, small concrete blocks, hand to
41、ols, etc.) 3.2 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 NOTE Structural members include any subframe, bracket, mounting, socket, bolt, pin, suspension or fl
42、exible shock absorption used to secure the system to the machine frame, but exclude mounting provisions that are integral with the machine frame. 3.3 deflection-limiting volume DLV orthogonal approximation of a large male, seated operator wearing normal clothing and a hard hat NOTE See ISO 3164. 3.4
43、 level I impact protection impact strength for protection from small falling objects (e.g. bricks, small concrete blocks, hand tools) encountered in operations such as highway maintenance, landscaping and other construction site services 3.5 level II impact protection impact strength for protection
44、from heavy falling objects (e.g. trees, rocks) for machines involved in site clearing, overhead demolition or forestry 3.6 representative test test of a specimen whose material, dimensional and processing requirements are typical of production FOPS 4 General The FOPS may be integrated into the opera
45、tor cab structure. This test procedure is generally destructive of the FOPS assembly, as permanent deformation will occur to the structure, and might not reproduce structural deformations, owing to variation in the actual impact of the falling objects. Two levels of performance criteria are specifie
46、d for impact protection, based on the machine end use. a) Level I: protection against the impact of a round test object dropped from a height sufficient to develop an energy of 1 365 J. See Figures 1 a) and 2 a). b) Level II: protection against the impact of a cylindrical test object dropped from a
47、height sufficient to develop an energy of 11 600 J. See Figures 1 b) and 2 b). The drop height of the test object is defined as a function of its mass, as shown in Figure 1. NOTE Although FOPS meeting these criteria do not give crush protection under all the circumstances in which the machine could
48、be struck from above, it is expected that protection from penetration will be ensured under conditions a) and b).
