This standard specifies the measurement and evaluation of mechanical vibrations to understand shaft vibrations by directly measuring a) changes in vibration behavior, b) excessive dynamic loads, and c) monitoring semi-longitudinal clearances of rotating shafts. Provides general guidelines for standards. This standard is applicable to measurements of semi-longitudinal absolute and relative axial vibrations, but not torsional and axial vibrations. The procedure is applicable to both machine operational monitoring and acceptance testing on a test stand and after installation. This guideline also stipulates the limit values during operation. Remarks 1. Evaluation criteria classified by type of machine are specified in each part of ISO 7919-1 and later. Guidelines for determination are provided in Annex A. 2. Since the measurements specified in this standard are in most cases carried out on the shafts of machines, the term "shaft vibration" is used throughout this standard. However, if measurements of other rotating elements are found to be more suitable, this standard can also be applied to measurements of other rotating elements, as long as the idea of this guideline is followed. The term “operational monitoring” in this standard is used to mean vibration measurements made during normal machine operation. This standard covers the use of a variety of different measurands and measurement methods, provided they are sufficiently defined so that their interrelationships are well understood and their limits of applicability have been established. Good too. This standard does not apply to reciprocating machines.
