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. While these aren’t always the only factors that need to be considered when identifying faults, the standard is very useful for performing basic vibration analysis.

ISO 10816-3 specifically applies to machine sets which have a power above 15 kW and operating speeds between 120 and 15,000 RPM. This category includes common industrial motors, pumps, generators, rotary compressors, blowers and fans, and several types of turbines. Of course, some machines have power requirements or speeds outside the scope of the standard; however, the majority of the machines you’re likely to encounter can be evaluated according to these guidelines.

By taking a few measurements in terms of vibration velocity and using the chart shown above, it’s possible to make good use of vibration data no matter your level of expertise. Referencing the ISO 10816-3 guidelines helps you quickly identify problem machines and perform targeted maintenance before more serious damage occurs. It’s a valuable, easy-to-use tool for more effective condition-based monitoring.
