Amendment of the European Machinery Directive has made it necessary to review the previously valid standard, EN ISO 3449:2005, in terms of the essential requirements of the new European Machinery Directive, 2006/42/EC. This standard contains specifications meeting the essential requirements s

28、tional Standard provides performance criteria for falling-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
29、 different sizes and masses. Its laboratory tests are 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 Sta
30、ndard 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. EN ISO
31、3449:2008 (E) 4DIN EN ISO 3449:2009-07 1 Scope 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
32、 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 ad
33、ditional 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 guidance to the manufacturers of roll-over or falling-object protective structures should it be decided to provide su
34、ch protection for these or other machines for a particular application. 2 Normative references The following referenced documents are indispensable for the application of this document.

42、 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 will occur to the structur
43、e, 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 he
44、ight 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 11 600 J. See Figures 1 b) and 2 b). The drop height of the test object is defined as a functio
45、n 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 be struck from above, it is expected that protection from penetration will be ensured under conditions a) and b).
