1. Routine maintenance, which consists of specific procedures that are
performed on a regular schedule. These procedures are designed to
detect, preclude, or mitigate degradation of a facility system (or its
components). The goal of routine, scheduled maintenance is to min-
imize each component's degradation and thus maintain, or even ex-
tend, the useful life of the component.
2. Predictive maintenance uses routine inspection and evaluation, test-
ing, and analysis to augment routine, scheduled maintenance pro-
cedures by detecting the onset of component degradation and to
