  • Equipment Failure Rate - an overview | ScienceDirect Topics

    Equipment failure rates (events/time) also can be used to quantify reliability. A higher failure rate or a greater number of failure incidences will directly translate to less-reliable equipment. The failure rate of any given piece of equipment can be described by a "bathtub" curve (see Figure 11.3).The bathtub curve is divided into three sections.
