適用范圍：1.1 This International Standard specifies, in accordance with ISO 10326-1, a laboratory method for measuringand evaluating the effectiveness of the seat suspension 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 criteria for 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 spectral classes required for the following earth-movingmachines. Each class defines a group of machines having similar vibration characteristics: rigid frame dumpers > 4 500 kg operating mass1 articulated frame dumpers scrapers without axle or frame suspension2 wheel-loaders > 4 500 kg operating mass1) graders wheel-dozers soil compactors (wheel type) backhoe-loaders crawler loaders crawler-dozers ≤ 50 000 kg operating mass compact dumpers ≤ 4 500 kg operating mass compact loaders ≤ 4 500 kg operating mass skid-steer loaders u 4 500 kg operating mass1.4 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 not require suspension for the attenuation of transmittedvibration: excavators, including walking excavators and cable excavators4 trenchers landfill compactors non-vibratory rollers milling machines pipelayers finishers vibratory rollers1.5 The tests and criteria defined in this International Standard are intended for operator seats used in earthmoving machines of conventional design.NOTE Other tests may be appropriate for machines with design features that result in significantly different vibration characteristics.1.6 Vibration which reaches the operator other than through his seat, for example that sensed by his feet on the platform or control pedals or by his hands on the steering-wheel, is not covered.
