CAN/CSA-M5007-94

This National Standard of Canada is equivalent to International Standard ISO 5007:1989. This Standard specifies a method for measuring and evaluating the effectiveness of the seat in reducing the vertical whole-body vibration transmitted to the operator of an agricultural tractor. 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. This Standard applies to seats fitted to agricultural wheeled tractors and rubber-tired skidders as defined by CSA Standard M6814, within specified tractor classes, each class being defined as a group of tractors having similar vibration characteristics (see table 2). Input vibrations for tractors not in a defined class may be measured at the seat attachment point during field operations and used for input to the vibration test table.
