IEC 60300-3-14:2004 - Overview

Standard Reference: IEC 60300-3-14:2004
Title: Dependability management - Part 3-14: Application guide - Maintenance and maintenance support

IEC 60300-3-14 is an application guide that defines a generic framework of management, processes and minimal common practices for maintenance and maintenance support to achieve required dependability throughout an item’s life cycle. It applies to all types of items (products, equipment and systems, including hardware and associated software) where maintenance is needed to meet functionality, safety, regulatory and economic requirements.

Key topics and technical requirements

The standard addresses the following technical subjects in a generic, life‑cycle oriented way:

• Life cycle aspects: guidance for maintenance across concept, design, manufacturing, installation, operation/maintenance and disposal phases.
• Maintenance policy and management responsibility: management commitment, customer needs, planning, authority and communication.
• Maintenance processes: identification, analysis, preparation and execution of maintenance tasks; preventive vs corrective maintenance.
• Indenture levels and echelons: structuring maintenance responsibilities and support levels.
• Maintenance support resources: human resources and training, infrastructure, support equipment, maintenance facilities, and built‑in test equipment (BITE).
• Information and documentation: maintenance documentation, maintenance information systems and computerized maintenance management.
• Materials and spare parts: quantification, identification and provisioning processes for spares.
• Measurement, analysis and improvement: monitoring customer‑related and maintenance‑related metrics, assessment, continuous improvement and managing modifications.
• Factors affecting maintenance: design and operational factors (informative annex).

Practical applications and who uses it

IEC 60300-3-14 is practical for organizations that need to establish or improve structured maintenance and support to meet dependability targets:

• Maintenance managers and planners - for developing maintenance policies, planning tasks and spare provisioning.
• Reliability and asset management engineers - to integrate maintenance into dependability and lifecycle planning.
• Systems and design engineers - to consider maintainability and supportability during design and development.
• Logistics, procurement and operations teams - for setting up infrastructure, training, documentation and logistics for maintenance.
• Regulators and contract managers - to specify minimum maintenance support requirements in procurement and compliance contexts.

Use cases include creating maintenance programs, choosing preventive vs corrective strategies, designing support facilities, establishing CMMS data and spare parts strategies, and measuring maintenance performance.

Related standards

• IEC 60300-1 / IEC 60300-2 - broader dependability management guidance referenced by this part.
• Integrated Logistic Support (ILS) practices - IEC 60300-3-14 offers a more general approach applicable where ILS is not fully implemented.

INTRODUCTION
The provision of maintenance and maintenance support is a key element in ensuring the

dependability of items (products, equipment and systems) throughout their life cycle. Proper

functionality, capability and dependability performance are achieved by providing the

necessary maintenance and maintenance support in conjunction with appropriate design,

quality manufacturing, and sound operating practices.

The amount and type of maintenance and maintenance support depends on customer needs,

the nature of the item, its condition, required availability and other factors. As these factors

change, especially during the operation and maintenance phase, maintenance and

maintenance support may need to be adjusted.
A number of different functions, such as maintenance management and asset management,
include maintenance and maintenance support. This standard does not preclude their use, but
does indicate what should be addressed under these headings.
Inadequate, excessive or incorrect maintenance can cause failures, which may significantly
reduce the availability of items and result in greatly increased cost due to loss of performance
and possible secondary damage. The reduced availability often produces operational
penalties and a consequent loss of revenue, which can be significantly greater than the cost
of maintenance or even the cost of the original failure. Safety may also be affected and in
some industries this may be the most important consideration.
This standard provides a more general approach to maintenance and maintenance support
than used in integrated logistic support (ILS). ILS is a method by which all logistic support
services are considered and provided for customers as an integral part of product
development. This standard addresses the case for complex systems where maintenance and
maintenance support need to be adjusted to specific situations during both the design phase
and the operation and maintenance phase.

Part 3-14: Application guide –

Maintenance and maintenance support

1 Scope
This part of IEC 60300 describes a framework for maintenance and maintenance support and
the various minimal common practices that should be undertaken. The purpose of this
standard is to outline, in a generic manner, management, processes and techniques related to
maintenance and maintenance support that are necessary to achieve adequate dependability
to meet the operational needs of the customer.
NOTE 1 Maintenance and maintenance support are a major element of dependability as described in IEC 60300-1
and IEC 60300-2.
In some cases, regulatory and other mandatory requirements need to be considered.
Maintenance and maintenance support requirements and obligations may therefore need to
be specified in a contract, which cites this standard.
This standard is intended for use by a wide range of suppliers, maintenance support
organizations and users and can be applied to all items.
This standard is applicable to items, which include all types of products, equipment and
systems (hardware and associated software). Most of these require a certain level of
maintenance to ensure that their required functionality, dependability, capability, economic,
safety and regulatory requirements are achieved.
NOTE 2 For consistency, this standard will use the term “item” as defined in 3.1.5, except where the context
requires otherwise.

4 Maintenance and maintenance support overview
4.1 Life cycle aspects
4.1.1 General
Maintenance and maintenance support need to be considered during all phases of the life
cycle. The specific tasks that need to be carried out are outlined in this clause and are
illustrated in Figure 1.
The major maintenance driver is the initial design, which determines the maintainability of an
item. Where an item is designed by one organization and used as part of a larger system or
used within different applications or environments, the design of the system has to ensure
that the inherent maintainability of the item is not degraded.
The dependability that can be achieved during operation is greatly influenced by decisions
that are made during the early phases of the life cycle. Planning for maintenance and
maintenance support should be considered as early as possible so that trade-offs can be
considered between functional needs, capability, life cycle cost (see IEC 60300-3-3),
reliability, maintainability and maintenance support.

4.1.2 Scenarios for maintenance and maintenance support
There are different scenarios for planning and providing maintenance and maintenance
support, depending on who takes responsibility for their implementation and in which phase of
the life cycle they occur.
A common scenario for many items is that the manufacturer provides complete maintenance
and maintenance support services as an integrated component of the delivery of the product.
These services are either provided on a contractual basis or are accessed as needed by the
user. The planning and provision of maintenance and maintenance support can thus occur
during design and development and remains the primary responsibility of the manufacturer,
vendor or other outsourced support organization. The user of the product depends primarily
upon this network to supply total support services during the operation and maintenance
phase. In this case, the end user environment and support capabilities are known and the
application of integrated logistic support should apply in these cases (see IEC 60300-3-12)
with the development of the maintenance and maintenance support undertaken as part of the
design and development process.

60300-3-14  IEC:2004(E) – 13 –

Another common scenario is that item vendors provide only basic or standardized main-

tenance support planning. Users then provide the required maintenance and maintenance

support for their specific application, often using internal resources. This occurs especially

when existing products are combined into complex systems by another vendor or organization

and are then supplied to a user. The responsibility for developing maintenance and

maintenance support then needs to be established between the vendor and user.

Maintenance and maintenance support recommendations require flexibility because there is a

wide range of different support scenarios. Information on factors that may result in changes to

maintenance and maintenance support at the various stages of the life cycle by owners,
operators and users is provided in Annex A.

4.1.3 Concept and definition phase
It is important to consider maintenance and maintenance support at the earliest stage of the
life cycle. Decisions made at this point may enhance or limit the effectiveness of maintenance
support in later life cycle phases.
During the concept and definition stage, this can be achieved by identifying a conceptual
maintenance policy that consists of the following:
– general maintenance and maintenance support objectives, customer needs, regulatory
requirements and constraints;
– required availability, reliability, maintainability and testability;
– general maintenance and maintenance support definition.
4.1.4 Design and development phase
Specific maintenance and maintenance support needs are identified during the design and
development phase based on the needs identified in the previous phase. Availability,
performance, production, safety and economic objectives are often dependent on achieving a
high degree of reliability, maintainability and maintenance support. Maintainability aspects are
outlined in IEC 60300-3-10. Operational and environmental factors are also important
considerations. A failure mode, effects and criticality analysis (FMECA) may be carried out to
evaluate the design and identify unacceptable failure modes. These may be addressed by
redesign, restrictions to operational use, maintenance or some other solution.
For items such as software, consumer products or military equipment, maintenance and
maintenance support are planned, tested and provided during this phase. Customers should
be consulted to ensure their needs are met but they usually depend upon suppliers or other
support organizations to provide maintenance and maintenance support services during the
life of the product or systems. This scenario is known as custom development and an

integrated logistic support approach is recommended as described in IEC 60300-3-12.
In other instances, a supplier manufactures a product that is then integrated into a larger
system such as a manufacturing facility, process plant or telecommunications network by an
independent design and construction organization. The original supplier provides basic
maintenance support planning but the design and construction organization should consider
the consequences of the use of the products and integration in the final system design.
Final aspects of maintenance and maintenance support may be established and implemented
by the user, operator or customer (see Annex A). The developer of the maintenance and
maintenance support plan and the user should determine the maintenance concept early in
the design. Regardless of who finalizes maintenance and maintenance support needs, these
should be established prior to operation so that they can be planned properly. Maintenance
and maintenance support resources may be derived from a reliability centred maintenance
analysis as described in IEC 60300-3-11 or by other methods.

– 14 – 60300-3-14  IEC:2004(E)

Trade-offs may need to be made and maintenance and maintenance support may have to be

adjusted to optimize performance, reliability, maintainability, safety and cost. It may be

desirable to eliminate the need for maintenance if it is technically possible or economically

feasible.
Training documentation, aids and equipment need to be identified and provided at the time

that training is performed prior to operation and maintenance. This training will continue as

needed during the operation and maintenance phase.

It may be necessary to provide verification and testing of planned maintenance activities and

the effectiveness of maintenance support procedures, tools, documentation, facilities and

other resources during the design and manufacturing phases. This should include the
customer, operator or user to ensure that their needs are met (see IEC 60706-3).
4.1.5 Manufacturing phase
In addition to design and component selection, the quality of manufacturing also directly
affects the reliability of products and systems and subsequent maintenance efforts. Where
feasible, users should ensure that the level of reliability, maintainability and testability meets
their objectives so that maintenance and maintenance support can be achieved as planned
during the operation and maintenance phase.
The tools, support equipment and facilities needed to undertake maintenance activities should
be provided during this phase. The gathering of manufacturing information and maintenance-
related data may be important for maintenance and maintenance purposes. The need to
procure spare parts should also be considered at this stage.
4.1.6 Installation phase
Correct installation and commissioning of items is essential to successful use and operation.
Instructions and procedures provided by the manufacturer should be followed and items
should not be operated outside specified limits during testing activities.
Maintainability demonstrations and testing of maintenance support may be carried out during
this phase in addition to earlier testing carried out during the design and development phase.
Performance and other testing may provide a baseline for condition monitoring and
maintenance tasks.
4.1.7 Operation and maintenance phase
During the operation and maintenance phase, the user or operator implements the
maintenance and maintenance support planned during the design and development phase. If

these have not been fully determined, they need to be developed and documented as early as
possible (see Annex A).
For the initial warranty period, operating and maintenance practices defined by the
manufacturer should be carefully followed to ensure validity of the warranty in case of failure.
Organizational responsibilities should be defined and assigned for all maintenance and
maintenance support. The organization may choose to carry out all of the required
maintenance and maintenance support itself or to outsource some or all of them. If the user
outsources some or all of these activities, they still retain ultimate responsibility but it
becomes important to establish a service level agreement in order to specify contractual
obligations with these external organizations. Manufacturers may take responsibility for a
prescribed time period to provide technical support and resources such as spare parts, either
as a part of the original procurement agreement or in a subsequent maintenance agreement.
Maintenance and maintenance support needs to be reviewed on a regular basis to adjust for
changes in customer needs and operating conditions and for advances in maintenance
technology such as tools and condition monitoring methods. It may also need to be modified

60300-3-14  IEC:2004(E) – 15 –

as items age or on the basis of age exploration if a RCM programme has been implemented.

Whenever new systems are added or modifications are made, changes in maintenance and

maintenance support should be addressed.

4.1.8 Disposal phase
The need to replace and dispose of an item can be for a number of reasons including

obsolescence, inability to meet functional specifications, the withdrawal of maintenance

support capability by the manufacturer, or other external support resources, or for economic
reasons. Maintenance support may have to be modified or eliminated when disposal occurs.

The lack of suitable, cost effective maintenance support may itself lead to disposal of an item

as it becomes non-repairable, and therefore the availability of long-term support, throughout

the proposed life of the item, should always be examined.
4.2 Description of maintenance
4.2.1 General
Maintenance is the combination of all technical and administrative actions, including
supervisory actions, intended to retain an item in, or restore it to, a state in which it can
perform a required function.
Basic terms relating to maintenance and their interrelationship are illustrated in Figure 2.

4.2.2 Maintenance policy and concept
A maintenance policy defines the general approach for the provision of maintenance and
maintenance support based on the objectives and policies of owners, users and customers
(see 5.3). It influences the decisions made on maintenance activities and resources during
the complete life cycle of an item.

– 16 – 60300-3-14  IEC:2004(E)

The maintenance concept is the specific maintenance approach developed for items using the
different levels of maintenance based on the indenture levels. It makes use of maintenance

support resources within the framework of the maintenance policy and is performed by a

maintenance echelon.
4.2.3 Indenture levels
Items may be subdivided into a hierarchy (for example, facility, system, assembly, equipment

and component) or indenture levels against which maintenance tasks are prescribed. The set

of maintenance tasks to be carried out at a specified indenture level are referred to as the

level of maintenance. The level of maintenance can be broken down into units of work or

elementary maintenance activities. A sequence of elementary maintenance activities carried
out for a given purpose becomes the actual maintenance task.
4.2.4 Maintenance echelons
Organizational units where maintenance is carried out are referred to as the lines of
maintenance or maintenance echelons. These can be internal groups such as field mechanics
and personnel in repair shops or they can be external such as personnel in manufacturer
overhaul facilities.
4.2.5 Preventive and corrective maintenance
Preventive maintenance may be carried out at regular intervals or according to prescribed
criteria to reduce the probability of failure or degradation in order to retain the functioning of
an item or to detect a hidden fault. This can be condition based and achieved by monitoring
its condition until failure is imminent, or by functional checks to detect failure of hidden
functions, and then performing maintenance. It can also be predetermined, based on a fixed
interval (such as calendar time, operating hours, number of cycles) consisting of regular
refurbishment or replacement of an item or its components.
Corrective maintenance restores the functions of an item after failure has occurred or
performance fails to meet stated limits. Some failu

INTRODUCTION
Les dispositions de maintenance et le support de maintenance constituent un élément clé
pour assurer la sûreté de fonctionnement des entités (produits, équipement et systèmes)
durant leur cycle de vie. La fonctionnalité propre, la capabilité et la sûreté de fonctionnement
sont atteintes par l’apport de la maintenance nécessaire et du support de maintenance
combiné à une conception appropriée, à une fabrication de qualité et à des modes
opératoires robustes.
La quantité et le type de maintenance et de support de maintenance dépendent des besoins
du client, de la nature de l’entité, de son état, de la disponibilité requise et d’autres facteurs.
La maintenance et le support de maintenance peuvent nécessiter d’être ajustés au fur et à
mesure des évolutions de ces facteurs, plus particulièrement pendant le fonctionnement et la
phase de maintenance.
Nombre de fonctions différentes, telles que la gestion de la maintenance et la gestion des
biens, traitent déjà de la maintenance et du support de maintenance. Cette norme n’exclut
pas leur utilisation, mais indique ce qu’il est important d’appliquer.
Une maintenance incorrecte, excessive ou inadéquate peut entraîner des défaillances qui
peuvent réduire significativement la disponibilité des entités et résulter en des coûts accrus
dus à une perte de l’aptitude à fonctionner et des dommages secondaires possibles. La
disponibilité limitée produit souvent des pénalités opérationnelles et une perte conséquente
de revenu, qui peut significativement être plus importante que le coût de la maintenance ou
même de la défaillance originale. La sécurité peut également être touchée, et, dans certaines
industries, cela peut être la considération la plus importante.
Cette norme fournit une approche plus générale de la maintenance et du support de
maintenance que celle d’un support logistique intégré (ILS). ILS est une méthode par laquelle
tous les services de support logistique sont considérés et fournis comme une partie intégrante
du développement du produit. Cette norme aborde le cas de systèmes complexes où la
maintenance et le support de maintenance ont besoin d’être ajustés à des situations
spécifiques pendant la phase de conception et pendant la phase de fonctionnement et de
maintenance.

INTRODUCTION
The provision of maintenance and maintenance support is a key element in ensuring the
dependability of items (products, equipment and systems) throughout their life cycle. Proper
functionality, capability and dependability performance are achieved by providing the
necessary maintenance and maintenance support in conjunction with appropriate design,
quality manufacturing, and sound operating practices.
The amount and type of maintenance and maintenance support depends on customer needs,
the nature of the item, its condition, required availability and other factors. As these factors
change, especially during the operation and maintenance phase, maintenance and
maintenance support may need to be adjusted.
A number of different functions, such as maintenance management and asset management,
include maintenance and maintenance support. This standard does not preclude their use, but
does indicate what should be addressed under these headings.
Inadequate, excessive or incorrect maintenance can cause failures, which may significantly
reduce the availability of items and result in greatly increased cost due to loss of performance
and possible secondary damage. The reduced availability often produces operational
penalties and a consequent loss of revenue, which can be significantly greater than the cost
of maintenance or even the cost of the original failure. Safety may also be affected and in
some industries this may be the most important consideration.
This standard provides a more general approach to maintenance and maintenance support
than used in integrated logistic support (ILS). ILS is a method by which all logistic support
services are considered and provided for customers as an integral part of product
development. This standard addresses the case for complex systems where maintenance and
maintenance support need to be adjusted to specific situations during both the design phase
and the operation and maintenance phase.

Maintenance et support de maintenance
1 Domaine d'application
Cette partie de la CEI 60300 décrit un cadre pour la maintenance et le support de
maintenance et les diverses pratiques communes minimales qui peuvent être prises. L’objet
de cette norme est de souligner, d’une façon générique, la gestion, les procédés et
techniques liés à la maintenance et au support de maintenance qui sont nécessaires pour
atteindre une sûreté de fonctionnement adéquate répondant aux besoins opérationnels du
client.
NOTE 1 La maintenance et le support de maintenance constituent un élément majeur de la sûreté de
fonctionnement décrite dans la CEI 60300-1 et CEI 60300-2.
Dans certains cas, il faut prendre en considération les exigences réglementaires et
obligatoires. Il peut être nécessaire de spécifier dans un contrat citant cette norme les
exigences de maintenance, support de maintenance et obligations.
Cette norme est destinée à être utilisée par un grand nombre de fournisseurs, d’organisations
de support de maintenance et d’utilisateurs, et peut être appliquée à toute entité.
Cette norme est applicable aux entités, qui comprennent tout type de produits, équipements
et systèmes (matériel et logiciel associé). La plupart de ceux-ci nécessitent un certain niveau
de maintenance pour assurer que leurs exigences de fonctionnalité, de sûreté de
fonctionnement, de capabilité, de coût, de sécurité et de réglementation sont respectées.
NOTE 2 Pour plus de cohérence, cette norme utilisera le terme « entité » tel que défini en 3.1.5, sauf si le
contexte ne s’y prête pas.

Part 3-14: Application guide –
Maintenance and maintenance support
1 Scope
This part of IEC 60300 describes a framework for maintenance and maintenance support and
the various minimal common practices that should be undertaken. The purpose of this
standard is to outline, in a generic manner, management, processes and techniques related to
maintenance and maintenance support that are necessary to achieve adequate dependability
to meet the operational needs of the customer.
NOTE 1 Maintenance and maintenance support are a major element of dependability as described in IEC 60300-1
and IEC 60300-2.
In some cases, regulatory and other mandatory requirements need to be considered.
Maintenance and maintenance support requirements and obligations may therefore need to
be specified in a contract, which cites this standard.
This standard is intended for use by a wide range of suppliers, maintenance support
organizations and users and can be applied to all items.
This standard is applicable to items, which include all types of products, equipment and
systems (hardware and associated software). Most of these require a certain level of
maintenance to ensure that their required functionality, dependability, capability, economic,
safety and regulatory requirements are achieved.
NOTE 2 For consistency, this standard will use the term “item” as defined in 3.1.5, except where the context
requires otherwise.
