Maintenance and maintenance support
FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60300-3-14 has been prepared by IEC technical committee 56:
Dependability.
This bilingual version (2004-07) replaces the English version.
This first edition of IEC 60300-3-14 cancels and replaces IEC 60706-4, and provides a more

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.

DEPENDABILITY MANAGEMENT –
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.

3 Terms, definitions and acronyms
3.1 Terms and definitions
For the purposes of this document the following definitions apply.
3.1.1
corrective maintenance
maintenance carried out after fault recognition and intended to put an item into a state in
which it can perform a required function
NOTE In French, the term “dépannage” sometimes implies a provisional restoration.
[IEV 191-07-08:1990]
3.1.2
dependability
collective term used to describe the availability performance and its influencing factors:
reliability performance, maintainability performance and maintenance support performance
NOTE Dependability is used only for general descriptions in non-quantitative terms.
[IEV 191-02-03:1990]
3.1.3
indenture level
level of subdivision of an item from the point of view of a maintenance action
NOTE 1 Examples of indenture levels could be a subsystem, a circuit board, a component.
NOTE 2 The indenture level depends on the complexity of the item’s construction, the accessibility to subitems,
skill level of maintenance personnel, test equipment facilities, safety considerations, etc.
[IEV 191-07-05:1990]

individually considered
NOTE 1 An item may consist of hardware, software or both, and may also, in particular cases, include people.

[IEV 191-01-01:1990]
3.1.6
level of maintenance
set of maintenance actions to be carried out at a specified indenture level
NOTE Examples of a maintenance action are replacing a component, a printed circuit board, a subsystem, etc.

3.1.7
maintainability (performance)
ability of an item under given conditions of use, to be retained in, or restored to, a state in
which it can perform a required function, when maintenance is performed under given
conditions and using stated procedures and resources
NOTE The term “maintainability” is also used as a measure of maintainability performance (see 191-13-01).
[IEV 191-02-07:1990]
3.1.8
maintenance
combination of all technical and administrative actions, including supervision actions,
