27、r Standardization) is a worldwide federation of national standards 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

28、 right to be represented on that committee. International organizations, 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. Internati

29、onal Standards are drafted in accordance with the rules given 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

30、as an International Standard requires approval by at least 75 % 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.

31、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. Licensed Copy: Wang Bin, ISO/EXCHANGE CHINA STAND

It recognizes that there are various classes and sizes of machin

33、es 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 are a means of evaluating the characteristics of the structures used to protect the operator from localized i

34、mpact 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 evaluating characteristics of FOPS under loading and prescribes performance requirements for these structur

35、es under such loading in a representative test. For similar tests on FOPS for excavators and excavator-based machines, see ISO 10262.

37、ry 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

38、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 additional seat for operation of an attachment (e.g. attachment backhoe), or on machines with a

39、 power rating of less than 15 kW. NOTE This International Standard can be used to provide 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 reference

48、orestry 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 operator cab structure. This test procedure is generally destructive of the FOPS assembly, as permanent deformation

49、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 specified 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 height sufficient to develop an energy of
