A proper wall chart shouldn't just identify the type of fault; it should also classify the severity . The ISO 10816 standards (now updated to ISO 20816) are the gold standard for this.
Bearing defects progress through four distinct stages, which are heavily detailed on comprehensive charts:
The Vibration Analysis Wall Chart PDF is an essential companion for any reliability professional aiming to move from reactive maintenance to predictive precision. It translates the complex science of FFT spectrums into a visual language that anyone on the maintenance team can understand.
Distribution of a single, approved PDF file guarantees that all plant branches, reliability analysts, and third-party contractors reference the exact same diagnostic thresholds and criteria. Vibration Analysis Wall Chart Pdf
