Whole body vibration in mobile machinery - A pilot study of consequences of new evaluation methods (NT TR 516)

NT TR 516

  • Whole-body vibration emission from mobile workplaces must, in order to meet the EU ‘Machinery Directive’, be declared. A number of methods for the evaluation of whole-body vibration exposure have been standardised. Depending on the choice of evaluation method different conclusions as to the vibration exposure can be reached.
