ISO 7919

Mechanical vibration of non-reciprocating machines – Measurements on rotating shafts and evaluation criteria – Part 1:General guidelines (1986 edition)

This part of ISO 7919 sets out general guidelines for measuring and evaluating machinery vibration by means of measurements made directly on rotating shafts for the purpose of determining shaft vibration with regard to

• Changes in vibrational behavior;
• Excessive kinetic load;
• The monitoring of radial clearances.

It is applicable to measurements of both absolute and relative radial shaft vibrations, but excludes torsional and axial shaft vibrations. The procedures are applicable for both operational monitoring of machines and to acceptance testing on a test stand and after installation.

This International Standard does not apply to reciprocating machinery.
