Scope

This document establishes general principles for the measurement and evaluation of vibration using measurements made on rotating, non-rotating and non-reciprocating parts of complete machines. It is applicable to measurements of vibration on non rotating parts and to both absolute and relative radial shaft vibration with regard to the monitoring of radial clearances but does not generally apply to axial shaft vibration, unless stated. The general evaluation criteria, which are presented in terms of both vibration magnitude and change of vibration, relate to both operational monitoring and acceptance testing. They have been provided primarily with regard to securing reliable, safe, long-term operation of the machine while minimizing any adverse effects on associated equipment. This document also gives guidance on setting operational limits.

NOTE 1 The evaluation criteria for different machines are included in other parts of ISO 10816 and ISO 20816.

NOTE 2 The term “shaft vibration” is used throughout ISO 10816 (all parts) and ISO 20816 (all parts) because, in most cases, vibration measurements are made on machine shafts. However, ISO 10816 (all parts) and ISO 20816 (all parts) are also applicable to measurements made on other rotating elements of the machine if such elements are found or known to be more suitable, provided that the guidelines set in this document are met.

The evaluation criteria are only applicable to the vibration produced by the machine itself and not the vibration transmitted to it from outside.

This document does not apply to torsional vibration.

NOTE 3 For information regarding the evaluation of torsional vibration, see (e.g. ISO 3046‑5, ISO 22266‑1 or VDI 2039).
