Understanding the ISO 10816-3 Vibration Severity Chart

The ISO-10816 Vibration Severity Chart hovers above industrial machinery.

The Smart Machine Checker (SMC), and the Falcon (vibration data collector/analyzer) use Accurex™ automatic diagnostic software to determine vibration problems on rotating equipment. Accurex™ performs a first order diagnostic based on ISO 10816-3 specifications (based on overall vibration levels in velocity, in inches per second/peak, or mm/sec/rms), and a second order diagnostic based on several…

How Vibration is Measured (Cont.): Vibration Level Charts, ISO Values, and More

In Part 1 of How Vibration is Measured, we discussed how equipment vibration is measured.  An accelerometer mounted to a machine bearing vibrates.  This vibration in the accelerometer produces a voltage.  The amount of movement of the accelerometer determines the amount of voltage, and the severity.  The frequency of the voltage (how many times per…

Shock Factor and SFI

For years, vibration analysts have depended upon the ISO Vibration Severity Chart for the determination of machinery health.  Typically, this chart provides a level of certainty that would allow the analyst to look at the vibration levels, and if acceptable, move onto the next machine for analysis.   Some defects are determined in the waveform…
