The is a critical tool for maintenance engineers to assess the health of industrial machinery. It provides standardized limits for broadband vibration velocity (measured in mm/s RMS) to help identify potential mechanical issues before they lead to catastrophic failure. While formally superseded by ISO 20816-3:2022 , the original severity zones remain the global industry benchmark for evaluating machines with a power rating above 15 kW. Scope and Machine Classification
Most modern vibration data collectors (Fluke 810, SPM Leonova, Emerson AMS 2140, Adash VA5Pro) have the ISO 10816-3 chart pre-programmed. You simply input:
The is not just a table; it is a decision-making framework. It transforms vague "buzziness" into quantifiable risk. To implement it effectively in your facility: iso 10816-3 vibration severity chart
In the world of predictive maintenance and reliability engineering, few documents are as ubiquitous as the ISO 10816 series. For maintenance professionals managing pumps, fans, compressors, and motors, the is the gold standard for determining the health of rotating equipment.
Not suitable for continuous operation; requires investigation and scheduled maintenance. Zone D (Red) Unacceptable The is a critical tool for maintenance engineers
Always trend your data. A machine moving from 0.8 mm/s to 1.5 mm/s might still be "Good," but that 85% increase is a warning sign.
The machine uses spring isolators or rubber mounts. These setups have higher (more lenient) limits because the mounts allow for more natural movement. Typical Severity Limits (mm/s RMS) Scope and Machine Classification Most modern vibration data
Zone D represents vibration levels that are dangerous.
The standard (recently superseded by ISO 20816-3 ) is a global benchmark for evaluating the vibration severity of industrial machines with a power rating above 15 kW and speeds between 120 and 15,000 RPM . It measures broadband vibration velocity in mm/s RMS on non-rotating parts like bearing housings to assess machine health. Vibration Severity Evaluation Zones
The chart categorizes vibration into four distinct "Zones" to help operators determine the necessary actions:
