When most of us refer to inspection, we are thinking of running machines inspected routinely, say on daily rounds. Unarguably, this type of on-the-run inspection is critical to machine condition monitoring, but other types of inspections are important as well.
At its best, inspection seeks and finds the “precursors” to failure, also known as root causes. This is job one, for sure. Next, inspection must hunt down those elusive incipient failure conditions (the earliest detectable state) that can be as difficult as the sound of a “pin drop” for our senses to detect.
