Traditionally, non-destructive testing was concerned with identifying material defects (for example cracks and voids) with the use of X-ray, ultrasonic and similar techniques. Gradually, computerised signal processing and data interpretation and processing have started to play an increasingly important role. The result is that non-destructive techniques such as infrared thermography (IT), vibration analysis (VA) and acoustic emission (AE), originally used for the final inspection of products, are now used as condition monitoring techniques to periodically measure, trend and diagnose asset health and support maintenance activities by predicting the remaining useful asset life.

Originally, condition monitoring mainly used vibration and tribology/oil analysis techniques, but this has grown over the years to encompass fields such as thermal imaging, acoustic emission, electrical measurements, ultrasound and other condition monitoring techniques. The diagnostic and prognostic elements, in addition to increasingly sophisticated signal processing, use trends from repeated measurements at pre-defined time intervals (ie seconds, hours, days or weeks).

There are new concepts such as smart integrated systems, which incorporate multiple condition monitoring techniques that provide a holistic view of machine/asset health.
