Etymologically, the term maintenance comes from the word “maintain” and the suffix “ance”. By simple definition of the dictionary, it is the actions that aim to maintain something in good condition.

Normative definition

A first normative definition of maintenance was given by AFNOR en 1994 (Standard NFX 60-010):

all actions for maintaining or restoring property in a specified state or in a position to provide a specific service “.

Since 2001, it has been replaced by a new definition, now European (NF EN 13306 X 60-319):

“All technical, administrative and management actions during the life cycle of a property, intended to maintain or restore it in a state in which it may perform the required function.

In 2002, Afnor in the standard FDX 60-000 redefined maintenance as well (definition shared by EFNMS – European Federation of National maintenance Societies):

“All technical, administrative and management actions during the life cycle of a property, intended to maintain or restore it in a state in which it can perform the required function.” “

Different types of maintenance

Forecast or planned Maintenance

The standard Afnor NF en 13306 X60-319, ” conditional maintenance performed according to the extrapolated forecasts of the analysis and evaluation of significant parameters of the degradation of the property “.

Systematic Maintenance

The standard Afnor NF EN 13306 X60-319, ” preventive maintenance performed at predetermined time intervals or according to a defined number of units of use but without prior checking of the condition of the property “.

Conditional Maintenance

The standard Afnor NF EN 13306 X60-319, ” preventive maintenance based on monitoring the functioning of the property and/or significant parameters of this operation and incorporating the actions resulting therefrom“.

NOTE: “operation and parameter monitoring can be performed on a schedule, or on demand or on a continuous basis .”

Palliative Maintenance

The Afnor FD X60-000 standard defines palliative maintenance as ” a corrective maintenance action designed to enable a property to perform temporarily all or part of a required function “. Commonly referred to as ” troubleshooting “, palliative maintenance is mainly made up of temporary actions which must be followed by curative actions.

Curative Maintenance

The standard Afnor FD X 60-000 defines curative maintenance as a corrective maintenance Action designed to restore property in a specified state to enable it to perform a required function. The result of the actions carried out must be of a permanent nature.

Corrective Maintenance

The standard Afnor FD X 60-000 defines palliative maintenance as ” maintenance performed after fault detection and intended to deliver a property in a state in which it can perform a required function “.

The 5 maintenance levels according to the standard

The first 2 levels for self-maintenance:

Level 1

Simple adjustments, simple controls and inspections, exchange of consumables/accessories and safe cleaning operation without special tools. The operator, adjuster… will rely on standards of self-maintenance to operate.

Level 2

Standard exchange of consumables, lubrication, cleaning requiring a tooling, a dismantling of protection and a clearance. The line adjuster/leader will rely on clear and detailed maintenance instructions.

The last 3 levels for scheduled maintenance

Level 3

Change of functional sub-assemblies requiring adjustments, calibration of measuring devices, tools and a clearance. Most often these operations can be done on site by the qualified maintenance technician.

Level 4

Upgrading of functional sub-assemblies requiring adjustments, calibration of measuring devices, in a workshop equipped with the necessary means and by a specialist technician.

Level 5

Renovation, reconstruction or major improvement works in a workshop equipped with specific means. Most often these operations are carried out by the manufacturer itself.
