European foreword
This document (EN 15341:2019) has been prepared by Technical Committee CEN/TC 319
“Maintenance”, the secretariat of which is held by UNI.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by February 2020, and conflicting national standards shall
be withdrawn at the latest by February 2020.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 15341:2007.
The main technical changes compared to the previous EN 15341:2007 are the following:
— the standard was fully revised;
— the vision on all the Maintenance Components was enlarged, structuring the standard in a more
complete way maintaining the economical, technical, organizational KPI of the previous edition.
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia,
Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland,
Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Republic of North
Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United
Kingdom.
Introduction
Maintenance Key Performance Indicators (KPI) of the Maintenance Function apply to all the physical
assets either industrial, infrastructures or civil buildings or transportation systems, etc.
These indicators should be used to:
a) measure the status;
b) compare (internal and external benchmarks);
c) diagnose (analysis of strengths and weaknesses);
d) identify objectives and define targets to be reached;
e) plan improvement actions;
f) regular measurement of changes over time.
Maintenance of software alone is not covered in this document. However, maintenance of items and
systems containing software is considered.
1 Scope
This document lists Key Performance Indicators (KPIs) of the Maintenance Function and gives guidelines
to define a set of suitable indicators, to appraise and to improve effectiveness, efficiency and
sustainability in the maintenance of the existing physical assets either industrial, infrastructures,
facilities, civil buildings or transportation systems, etc. in the framework of the external and internal
influencing factors.

4 Maintenance function
The Maintenance Function is operating in various industrial plants, facilities, infrastructures, acting in
different frameworks and contexts with different sizes, structures, objectives, specific constraints and
influencing factors (see 5.2 and 5.3).
In this context, it is suitable to define an organizational Model of Maintenance Function, as standard
reference to be implemented in relation with required objectives, available resources, and existing
constraints.
This Model of Maintenance Function is reported in Figure 1.
The Model considers that for the Maintenance function to achieve the assigned objectives and excellence,
it shall use an appropriate combination or parts of the various disciplines as HSE (Health Safety
Environment), Administration, ICT (Information and Communication Technology), etc.
It is Management task:
a) to implement the appropriate resources, knowledge, rules, procedures activities;
b) to select how the maintenance needs to build and organize the various matters and disciplines in the
following Sub Functions/Areas:
— HSE on Maintenance;
— Maintenance Management;
— Maintenance People Competence;
— Maintenance Engineering;
— Organization and Support for Maintenance;
— Administration and Supply.
The maintenance function maintains the physical assets so that it can perform the required functions and
consequently, the management shall act in a core framework that involves:
— The company
— The available resources
— The application of ICT and Enabling Technologies (e.g. Industry 4.0)
Acknowledging the fast development within maintenance, both from organizational and technological
point, this document provides an overview of the content of sub-functions, activities, and tools to be
considered when establishing activities and indicators to reach the targets.
It is suitable to use all the disciplines of Maintenance Function in the integrated framework to achieve the
objectives assigned to the Maintenance of the Physical Assets with the support of ICT and Enabling
Technologies (e.g. Industry 4.0).
The size and the depth of utilization depends on the maturity degree of each maintenance department
and from its commitment to develop Maintenance activities towards the excellence.
During the life of each physical asset and its components, it is necessary to carry out maintenance
activities to repair the failures, contain the degradation and wear with appropriate preventive actions, so
as to lengthen the life of the unit and meet the required level of performance.
