ISO 2372 (10816) Standards provide guidance for evaluating vibration severity in machines operating in the 10 to 200Hz (600 to 12,000 RPM) frequency range. Examples of these types of machines are small, direct-coupled, electric motors and pumps, production motors, medium motors, generators, steam and gas turbines, turbo-compressors, turbo-pumps.

The ISO 10816-3 standard provides criteria for evaluating the vibration of machinery according to measurements taken on non-rotating parts, such as bearings, bearing pedestals, or housings. It serves as a general guideline for determining overall machine condition based on the magnitude of vibration and changes in vibration levels over time.

Vibration Diagnostic Guide 19 Typically, looseness is identified by an abnormally high running speed amplitude followed by multiples or 1/2 multiples. Harmonic peaks may decrease in amplitude as they increase in frequency (except at 2x, which, when measured in the vertical position, can be higher in amplitude).

If bearings are present, know the bearing identification number or its designation. If the machine contains, or is coupled, to a gearbox, know the number of teeth and shaft speeds. If the machine is driven with belts, know the belt lengths. The above information helps assess spectrum components and helps identify the vibration source.

The criteria of this part of ISO 10816 apply to in situ broad-band vibration measurements taken on the bearings, bearing pedestals, or housing of machines under steady-state operating conditions within the nominal operating speed range. They relate to both acceptance testing and operational monitoring. The evaluation criteria of this part of ISO 10816 are designed to apply to both continuous.
