Representatives of manufacturers and users of earth-moving machinery, and of the employers liability insurance associations contributed to this standard. Amendment of the European Machine
7、ry Directive has made it necessary to review the previously valid standard, EN ISO 7096:2000, in terms of the essential requirements of the new European Machinery Directive, 2006/42/EC. This standard contains specifications meeting the essential requirements set out in Annex I of the “Machinery Dire
8、ctive”, Directive 98/37/EC (valid until 28 December 2009), and the “revised Machinery Directive”, Directive 2006/42/EC, which takes effect on 29 December 2009, and which apply to machines that are either first placed on the market or commissioned within the EEA. This standard serves to facilitate pr
9、oof of compliance with the essential requirements of the directives. Once this standard is cited in the Official Journal of the European Union, it is deemed a “harmonized” standard and thus, a manufacturer applying this standard may assume compliance with the requirements of the Machinery Directive
10、(“presumption of conformity“). The International Standards referred to in clause 2 of this document have been published as the corres-ponding DIN EN ISO Standards with the same number, except for those below, which correspond as follows: ISO 2041:1990 similar to DIN 1311-4:1974, similar to DIN 5483-
11、1:1983 ISO 10326-1:1992 DIN EN 30326-1:1994 Amendments This standard differs from DIN EN ISO 7096:2001-11 as follows: a) Normative Annex ZA has been dropped. b) The informative Annexes have been restructured: Annex ZB is now Annex ZA and Annex ZC is now Annex ZB.

29、d text EN ISO 7096:2008 + AC:2009 (E)3DIN EN ISO 7096:2010-02 IntroductionThe operators of earth-moving machinery are often exposed to a low frequency vibration environment partlycaused by the movement of the vehicles over uneven ground and the tasks carried out. The seat constitutes thelast stage o
30、f 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 its suspension are acompromise between the requirements of reducing the effect of vibration and shock
31、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 vibrationparameters needs to be taken in context with the other requirements for the seat.The performa
32、nce 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 completeprotection of the operator against the effects of vibration and shock. They may be revised in the ligh
33、t 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 machinery used under severe but typical operating conditions. The test methods are based onISO 10326-1,
34、which is a general method applicable to seats for different types of vehicles.EN ISO 7096:2008 + AC:2009 (E)4DIN EN ISO 7096:2010-02 1 Scope1.1 This International Standard specifies, in accordance with ISO 10326-1, a laboratory method for measuringand evaluating the effectiveness of the seat suspens
35、ion in reducing the vertical whole-body vibration transmitted tothe operator of earth-moving machines at frequencies between 1 Hz and 20 Hz. It also specifies acceptance criteriafor application to seats on different machines.1.2 This International Standard is applicable to operator seats used on ear
36、th-moving machines as defined inISO 6165.1.3 This International Standard defines the input 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 articula

39、, the seat performance requirements are suitably provided by a cushion type seat.EN ISO 7096:2008 + AC:2009 (E)5DIN EN ISO 7096:2010-02 1.4 The following machines impart sufficiently low vertical vibration inputs at frequencies between 1 Hz and20 Hz to the seat during operation that these seats do n

41、n this International Standard are intended for operator seats used in earth-moving machines of conventional design.NOTE Other tests may be appropriate for machines with design features that result in significantly different vibrationcharacteristics.1.6 Vibration which reaches the operator other than
42、 through his seat, for example that sensed by his feet on theplatform or control pedals or by his hands on the steering-wheel, is not covered.2 Normative referencesThe following normative documents contain provisions which, through reference in this text, constitute provisions ofthis International S
