The work
24、of preparing International Standards is normally carried out through ISO technicalcommittees. Each member body interested in a subject for which a technical committee has been established hasthe right to be represented on that committee. International organizations, governmental and non-governmental
25、, inliaison with ISO, also take part in the work. ISO collaborates closely with the International ElectrotechnicalCommission (IEC) on all matters of electrotechnical standardization.International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.Draft Interna
26、tional 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.Attention is drawn to the possibility that some of the elements of this International St
27、andard may be the subject ofpatent rights. ISO shall not be held responsible for identifying any or all such patent rights.International Standard ISO 7096 was prepared by Technical Committee ISO/TC 127, Earth-moving machinery,Subcommittee SC 2, Safety requirements and human factors.This third editio

29、ent of the vehicles over uneven ground and the tasks carried out. The seat constitutes thelast stage of suspension before the driver. To be efficient at attenuating the vibration, the suspension seat shouldbe chosen according to the dynamic characteristics of the vehicle. The design of the seat and
30、its suspension are acompromise between the requirements of reducing the effect of vibration and shock on the operator and providinghim with stable support so that he can control the machine effectively.Thus, seat vibration attenuation is a compromise of a number of factors and the selection of seat
31、vibrationparameters needs to be taken in context with the other requirements for the seat.The performance criteria provided in this International Standard have been set in accordance with what isattainable using what is at present the best design practice. They do not necessarily ensure the complete
32、protection of the operator against the effects of vibration and shock. They may be revised in the light of futuredevelopments and improvements in suspension design.The test inputs included in this International Standard are based on a very large number of measurements taken insitu on earth-moving ma
33、chinery used under severe but typical operating conditions. The test methods are based onISO 10326-1, which is a general method applicable to seats for different types of vehicles.BS EN ISO 7096:2008EN ISO 7096:2008 (E)INTERNATIONAL STANDARD ISO 2000 All rights reserved 1Earth-moving machinery Labor

It also specifies acceptance criteriafor application to seats on different machines.1.2 This International Standard is applicable to operator seats used on earth-moving machines as defined inISO 6165.1.3 This International Standard defines the input
36、spectral classes required for the following earth-movingmachines. Each class defines a group of machines having similar vibration characteristics:Gbe rigid frame dumpers 4 500 kg operating mass1G29Gbe articulated frame dumpersGbe scrapers without axle or frame suspension2G29Gbe wheel-loaders 4 500 k
