The instructions for use shall give the following information concerning vibrations, expressed as acceleration (m/s2), and transmitted by portable handheld or hand-guided machinery or related products:
- a)the vibration total value from continuous vibrations to which the hand-arm system is subjected;
- b)the mean value of the peak amplitude of the acceleration from repeated shock vibrations, to which the hand-arm system is subjected;
- c)the uncertainty of both measurements.
The values referred to in the first subparagraph shall either be those actually measured for the machinery or related product in question or those established on the basis of measurements in respect of a technically comparable machinery or related product, which is representative of the state of the art.
If harmonised standards or common specifications adopted by the Commission in accordance with Article 20(3) cannot be applied, the vibration data shall be measured using the most appropriate measurement code for the machinery or related product.
The operating conditions during measurement and the methods used for measurement, or the reference of the harmonised standard applied, shall be specified.
