Corrective maintenance
Corrective maintenance is a maintenance task performed to identify, isolate, and rectify a fault so that the failed equipment, machine, or system can be restored to an operational condition within the tolerances or limits established for in-service operations.[1]
Definition
A French official standard defines "corrective maintenance" as maintenance which is carried out after failure detection and is aimed at restoring an asset to a condition in which it can perform its intended function (NF EN 13306 X 60-319 standard, June 2010).[2]
Corrective maintenance can be subdivided into "immediate corrective maintenance" (in which work starts immediately after a failure) and "deferred corrective maintenance" (in which work is delayed in conformance to a given set of maintenance rules).
Standards
The technical standards concerning corrective maintenance are set by IEC 60050 chapter 191 °Dependability and quality of service"[3]
The NF EN 13306 X 60-319 is a subset of IEC 60050-191.[4]
Choice
The decicion to choose corrective maintenance as method of maintenance, is a decision depending on several factors as the cost of down time, reliability characteristics and redundancy of assets.[5]
Methods
The steps of corrective maintenance are, following failure, diagnosis – elimination of the part, causing the failure – ordering the replacement – replacement of the part – test of function and finally the continuation of use.
The basic form of corrective maintenance is a step-by-step procedure. The object's failure triggers the steps. Modern technologies as the use of Industry 4.0 features reduce the inherant drawbacks of corrective maintenance.[6] by e.g. providing device history, fault patterns, repair advice or availability of spare parts.
