27、e 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
28、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 appl
29、ications, 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 o
30、r 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 verif
31、ication, 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 specifica
