Earth-moving machinery - Laboratory evaluation of operator seat vibration (ISO 7096:2000)

This International Standard specifies, in accordance with ISO 10326-1, a laboratory method for measuring and evaluating the effectiveness of the seat suspension in reducing the vertical whole-body vibration transmitted to the 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. This International Standard is applicable to operator seats used on earth-moving machines as defined in ISO 6165. This International Standard defines the input spectral classes required for the following earth-moving machines. 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 u 50 000 kg operating mass1), 3- - compact dumpers u 4 500 kg operating mass1) - compact loaders u 4 500 kg operating mass1) - skid-steer loaders u 4 500 kg operating mass1) The following machines impart sufficiently low vertical vibration inputs at frequencies between 1 Hz and 20 Hz to the seat during operation that these seats do not require suspension for the attenuation of transmitted vibration: - excavators, including walking excavators and cable excavators4- - trenchers - landfill compactors - non-vibratory rollers - milling machines - pipelayers - finishers - vibratory rollers The tests and criteria defined in this International Standard are intended for operator seats used in earthmoving machines of conventional design. 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.

Foreword
ISO (the International Organization for 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 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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
Draft International 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 Standard may be the subject of
patent 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 edition cancels and replaces the second edition (ISO 7096:1994), which has been technically revised.
ISO 7096:2000(E)
Introduction
The operators of earth-moving machinery are often exposed to a low frequency vibration environment partly
caused by the movement of the vehicles over uneven ground and the tasks carried out. The seat constitutes the
last stage of suspension before the driver. To be efficient at attenuating the vibration, the suspension seat should
be chosen according to the dynamic characteristics of the vehicle. The design of the seat and its suspension are a
compromise between the requirements of reducing the effect of vibration and shock on the operator and providing
him 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 vibration
parameters 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 is
attainable using what is at present the best design practice. They do not necessarily ensure the complete
protection of the operator against the effects of vibration and shock. They may be revised in the light of future
developments and improvements in suspension design.
The test inputs included in this International Standard are based on a very large number of measurements taken in
situ on earth-moving machinery used under severe but typical operating conditions. The test methods are based on
ISO 10326-1, which is a general method applicable to seats for different types of vehicles.
