| Word of Phrase |
|
Definition |
| Failure |
|
When equipment condition reaches an unacceptable
level. Example: A motor may run, but the temperature is 250 °F
(unacceptable) |
| Failure Code |
|
A classification of a failure. |
| Failure Developing Period |
|
The time lapsed between a failure and the
break down. illustration |
| Failure Mode |
|
Any event that may cause a failure. |
| Failure Mode and Effects Analysis
(FMEA) |
|
Analysis tool to Identify Failure modes,
assign priorities to each failure mode based on cost and occurrences.
|
| Failure Rate |
|
An average of how often a component, equipment
or system fails in a given time period. |
| Feedback |
|
In maintenance. Most commonly
used when referring to written description of the work completed on
a work order. |
| Fixed Time Maintenance (FTM) |
|
This tactic provides for scheduled overhauls
or replacements of components often based on recommendation from the
equipment vendor, general plant experience with similar components
or analysis of the maintenance history of an individual piece of equipment
and its components. Note: Only 10-15% of
all component types have a predictable failure rate. Cost effective
use of FTM is therefore limited. |
| Frequency of Inspection |
|
The time period between a repetitive inspection.
The inspection frequency should be based on the failure developing
period. Note: A rule of thumb is that the
inspection frequency should be: Failure Developing Period/ 2. |
