Human response to vibration - Measuring instrumentation (ISO 8041:2005)
SS-EN ISO 8041-1:2017
SS-EN ISO 8041:2005/AC:2008
This International Standard specifies the performance specifications and tolerance limits for instruments designed to measure vibration values, for the purpose of assessing human response to vibration. It includes requirements for pattern evaluation, periodic verification and in-situ checks, and the specification of vibration calibrators for in-situ checks.
Vibration instruments specified in this International Standard can be single instruments, combinations of instrumentation or computer-based acquisition and analysis systems.
Vibration instruments specified in this International Standard are intended to measure vibrations for one or more applications, such as
-- hand-transmitted vibration (see ISO 5349-1),
-- whole-body vibration (see ISO 2631-1, ISO 2631-2, ISO 2631-4), and
-- low-frequency whole-body vibration in the frequency range from 0,1 Hz to 0,5 Hz (see ISO 2631-1).
Vibration instruments can be designed for measurement according to one or more of the frequency weightings defined within each of these applications.
Three levels of performance testing are defined in this International Standard:
a) pattern evaluation, i.e. a full test of the instrument against the specifications defined in this International Standard;
b) periodic verification, i.e. an intermediate set of tests designed to ensure that an instrument remains within the required performance specification, and
c) in-situ checks, i.e. a minimum level of testing required to indicate that an instrument is likely to be functioning within the required performance specification.
