This International Standard states the requirements which a measuring instrument for vibration severity of machines should meet if inaccuracies of measurement, particularly when making comparisons between one machine and another, are not to exceed a specific value. Instruments meeting the requirements of this International Standard are suitable for use in carrying out the procedures specified in ISO 2372 and ISO 2373 and are designated "Measuring instruments for vibration severity in rotating and reciprocating machines".
The instruments covered by this International Standard give direct indication or recording of root-mean-square vibration velocity, which is defined as the measuring unit of the vibration severity.
NOTES
1 A method of checking true root-mean-square indication is described in an annex.
2 Subject to I imitation of the measuring-frequency range, these instruments may be used for other applications where similar accuracy of measurement is required, for example measurement of vibration velocity of structures, tunnels, bridges, etc.
