Mechanical vibration — Uncertainty of the measurement and evaluation of human exposure to vibration ISO/TS 22704:2022

Publication date:   Apr 6, 2022

Scope

This document specifies methods for determining the uncertainty of the measurement and evaluation of human exposure to vibration. It applies to measurements of vibration quantities (measurands), calculated following a relevant measurement model on the basis of directly measured values, to evaluate
a) human exposure to hand-transmitted vibration at the workplace,
b) vibration emission of hand-held and hand-guided machinery in a laboratory setting,
c) human exposure to whole-body vibration at the workplace, and
d) whole-body vibration emission of vehicles.
Examples of the application of the individual methods in practical situations are provided in the annexes.
In this document a measurement error is defined as the difference between a measured and a reference quantity value.
In this document “uncertainty” does not include errors that result from bad measurement strategies, faulty use of measurement equipment or other mistakes.
