Introduction
EN 17485 introduces methods and procedures about maintenance within physical asset management for
all the levels and functions of the organizations’ management, including corporate planning management,
plant management, technical management, production management, financial management, asset
management, maintenance management, and quality management.
EN 16646 ‘Maintenance - Maintenance within physical asset management’ was published in December
2014. Since it gives a general framework to allow and determine the role and tasks of maintenance within
the larger frame of physical asset management, but does not introduce detail methods and procedures to
implement or establish it. The aim of EN 17485 is to close this gap.
This document addresses the principles of physical asset management, which are relevant from the
maintenance point of view. This document offers a framework for a systematic management approach.
The aims of this document are to:
— create and systematize the link between business, physical asset management and maintenance
activities of organizations;
— indicate external and internal influencing factors and their effect on physical asset and maintenance
management;
— promote cross-functional cooperation;
— address transparency in organizational decision making;
— address simulation and visualization as effective tools to support decision making;
— address uncertainty management to improve the quality of decision making;
— improve information management as an activity to achieve the above-mentioned objectives;
— address the sustainability of operations.
These targets improve the chances of success in meeting the physical asset management challenges
mentioned in EN 16646. It mentions several reasons why physical asset management is nowadays more
important than ever before. The same reasons are valid when we evaluate the importance of methods
and procedures.
This document introduces methods and approaches to build a bridge between maintenance and the other
functions.
Many benefits can be achieved when applying the methodology presented in this document:
— economically more efficient, effective and profitable use of capital: ‘turnover of and return on assets’;
— more accurate long-term life cycle decisions;
— integrated investment and maintenance planning;
— integrated approach for the production function (assets, operation and maintenance);
— direction given to maintenance strategies and activities;
— improved position for maintenance among the other company functions;
— improved assessment of performance and control;
— enhanced capability to operate within extended enterprise ecosystems (including
customers/suppliers);
— enhanced reputation;
— more sustainable use of capital.

---------------------- Page: 6 ----------------------
SIST EN 17485:2021
EN 17485:2021 (E)
Further and maybe even greater benefits are now being found through improved credibility in the eyes
of customers, regulators and other stakeholders. Physical asset management also results in much greater
engagement and motivation of the workforce, and in more sustainable, continual improvement business
processes. Physical asset management builds up the required link between maintenance management
and the organizational strategic plan and gives direction to maintenance activities.
The standards EN 16646 and EN 17485 build the bridge between ISO 5500x (Asset management system
standards) and the EN maintenance standards. ISO 55001 states that organizations should determine e.g.
the organizational context, requirements for the assets, decision criteria, strategic asset management
plan and asset management plan (including maintenance). However, it does not describe how to do it.
Respectively, maintenance standards often introduce e.g. the concept of the required function or the
concept of maintenance strategy, but do not explain how they have been determined. EN 17485
introduces a methodological framework which advises organizations to implement the requirements
presented in ISO 55001. By doing this it creates the bridge between the several maintenance standards
and ISO 5500x in order to give an applicable starting point to the more detailed documents for the specific
sub-functions of maintenance (See Figure 1).

In Figure 2, life cycle management covers 3 main life cycles stages (see in detail 5.2):
1. Acquisition stages (6 sub-stages) where the impact of maintenance on asset solutions have been
indicated and the first contributions on maintenance strategies and programmes have been created;
2. Utilization stages (3 sub-stages) which are:
— Utilization of physical assets;
— Maintenance of physical assets;
— Replacements including reconditioning, improvements, modifications, modernizations;
3. Disposal stage.

1 Scope
This document specifies methods and procedures when applying physical asset management as a
framework to take maintenance into account as an influencing factor within an organizations’ strategic
and tactical decisions on its physical assets, and when applying physical asset management as a
framework to maintenance activities. It also specifies the relationship between organizational strategic
plan and the maintenance management system at a methodological level and describes the interrelations
between maintenance process and all the other physical asset management processes at a procedural
level.
This document is applicable to managing the physical assets of organizations of all sizes especially
organizations producing goods and services with physical assets. It introduces methods and procedures
for all the levels and functions of the organizations’ management such as corporate planning
management, plant management, technical management, production management, financial
management, asset management, maintenance management, quality management, etc. The focus of the
document is at the asset portfolio and system levels and consists of guidance and recommendations. It
does not apply to certification, regulatory, or contractual use.
However, if specific documents exist for a particular domain, it is important to also consider those
documents.

Introduction
EN 16646 ’ Maintenance - Maintenance within physical asset management’ was published in December
2014. It gives a general framework to determine the role and tasks of the maintenance within the larger
framework of physical asset management. In EN 16646, neither the methods and procedures to
implement and establish the standard are defined nor which kind of methods would be available when
applying the instructions of the standard are recommended. EN 17485 introduces methodological
support for Maintenance within Physical Asset Management.
This document introduces methods and procedures about maintenance within physical asset
management for all the levels and functions of the organisations’ management, including corporate
planning management, plant management, technical management, production management, financial
management, asset management, maintenance management, and quality management.
This document is targeted to promote the principles of physical asset management, which can be
considered essential to meet with success the increasing requirements of the organization’s business
and technological environment, including safety and environmental issues. Similarly, this document
gives direction to maintenance activities within the physical asset management framework, offering
methodological support for a systematic and systemic management approach. The aims of this
document are to:
• create and systematize the link between business, physical asset management and maintenance
activities of organisations;
• indicate external and internal influencing factors and their effect on physical asset and maintenance
management;
• prevent silo behaviour and promote cooperation between different organizational functions;
• promote transparency in organisational decision making;
• promote simulation and visualization as effective tools to support decision making;
• promote uncertainty management to improve the quality of decision making;
• improve information management as an activity to achieve the above-mentioned objectives;
• promote sustainability of operations.
These targets improve the chances of success in meeting the physical asset management challenges
mentioned in EN 16646. EN 16646 mentions several reasons why physical asset management is
nowadays more important than ever before. The same reasons are valid when we evaluate the
importance of methods and procedures.
Physical asset management and maintenance as a part of physical asset management has become a
more essential part of the organizations’ activities during the last decades for several reasons,
including:
— globalization and increasing competition;
— growing turbulence in the market;
— growth of capital intensity in some industry sectors;
— aging of asset systems;

---------------------- Page: 7 ----------------------
oSIST prEN 17485:2020
prEN 17485:2020 (E)
— increased pressure to improve the added value of maintenance;
— increased requirements from the safety and environmental point of view;
— organisations are in tighter collaboration and networking with other businesses, posing pressing
requirements for managing the dependability of physical assets;
— ‘silo’ behaviour which keeps maintenance and other life cycle processes separated.
The above changes in the organisations’ working environment create demand for more holistic
approaches in business planning, better cooperation between different functions of the organisations,
more systematic and analytic management, deeper understanding of effects of uncertainties on the
activities of the organisations and more frequent modification of prevailing plans and business
approaches. Therefore, maintenance is one of the important functions. This document introduces
methods and approaches to build a bridge between maintenance and the other functions.
Many benefits can be achieved when applying the methodology presented in this document:
— economically more efficient, effective and profitable use of capital: “turnover of and return on
assets”;
— more accurate long-term life cycle decisions;
— integrated investment and maintenance planning;
— integrated approach for production function (assets, operation and maintenance);
— direction to maintenance strategies and activities;
— improved position for the maintenance among the other company functions;
— improved assessment of performance and control;
— enhanced capability to operate within extended enterprise ecosystems (including
customers/suppliers);
— enhanced reputation;
— more sustainable use of capital.
Further and maybe even greater benefits are now being found through improved credibility in the eyes
of customers, regulators and other stakeholders. Physical asset management also results in much
greater engagement and motivation of the workforce, and in more sustainable, continual improvement
business processes. Physical asset management builds up the required link between maintenance
management and organizational strategic plan and gives direction to maintenance activities.
The standards EN 16646 and EN 17485 build the bridge between ISO 5500x (Asset management
system standards) and the EN maintenance standards. While maintenance standards define required
elements (“What to do”), EN 17485 guides through the implementation of maintenance of physical
assets. As a methodological framework it overlaps slightly with the above-mentioned standards in
order to give an applicable starting point to the more detailed documents for the specific subfunctions
of maintenance (See Figure 1).

1 Scope
This document introduces methods and procedures when applying physical asset management as a
framework to take maintenance into account as an influencing factor within an organisations’ strategic
and tactical decisions on its physical assets, and when applying physical asset management as a
framework to maintenance activities. It also introduces the relationship between organisational
strategic plan and the maintenance management system at a methodological level and describes the
interrelations between maintenance process and all the other physical asset management processes at
a procedural level.
This document may be applied to managing the physical assets of organisations of all sizes. It
introduces methods and procedures for all the levels and functions of the organisations’ management
such as corporate planning management, plant management, technical management, production
management, financial management, asset management, maintenance management, quality
management etc. The focus of the document is at the asset portfolio and system levels and consists of
guidance and recommendations. It is not intended to be used for certification, regulatory, or
contractual use.
However, if specific documents exist for a particular application, those documents should also be
considered.
NOTE Typical examples for asset systems or composition of asset systems are production processes,
production lines, production units, plant with several production lines.
