Mechanical vibration — Measurement and evaluation of human exposure to hand-transmitted vibration — Part 3: Isolated and repeated shocks using the frequency range of ISO 5349-1

Vibrations mécaniques — Mesurage et évaluation de l’exposition des individus aux vibrations transmises à la main — Partie 3: Évaluation de chocs isolés ou répétés en utilisant la gamme de fréquences couverte par l’ISO 5349-1

Abstract / scope

This document specifies the general requirements for the measurement and evaluation of human exposure to hand-transmitted shock vibrations. For the purposes of this document, hand-transmitted shock vibration is any impactive or impulsive vibration that the machine or tool produces as a sequence of single events (isolated shock vibrations) linked by periods of no, or lower vibration.

This document specifies parameters for the evaluation of machinery emissions of hand-transmitted shocks in the frequency range covered by ISO 5349-1 (nominally the frequency range covered by the octave bands from 8 Hz to 1 000 Hz).

NOTE            It is recognised that shock vibration often includes substantial high-frequency vibration energy. Therefore, reporting of information on hand-transmitted shock at higher frequencies that those specified in this document can be valuable.
