PREPARATION OF PARTS LISTS
FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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 National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical specifications, technical reports or guides and they are accepted by the National
Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 62027 has been prepared by subcommittee 3B: Documentation, of
IEC technical committee 3: Documentation and graphical symbols, in cooperation with
subcommittee 1: Basic conventions, of ISO technical committee 10: Technical drawings,
product definition and related documentation.
The text of this standard is based on the following documents:
FDIS Report on voting
3B/289/FDIS 3B/295/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 3.
Annexes A, B, C and D are for information only.
The committee has decided that the contents of this publication will remain unchanged until
2009. At this date, the publication will be
• reconfirmed;
•
withdrawn;
•
replaced by a revised edition, or
• amended.

INTRODUCTION
A parts list is primarily used to list and specify the constituent objects (components) of the
overall object or system to which the parts list applies.
It is generally recognized that information on products, installations and systems can be
organized on the basis of tree-like, hierarchical structures. The structure represents the way
in which an industrial process or a product is subdivided into smaller processes or sub-
products, designated by the general term “objects”. In the context of this International
Standard, "object" refers to any entity treated in the process of design, engineering,
realization, operation, maintenance, and demolition of a plant, installation, system, equip-
ment, etc., or part thereof, in accordance with the definition in 3.1.1.
NOTE In the context of other standards, the term “item” is sometimes used with the same meaning as “object”.
Depending on the “aspect” (see 3.1.3), different structures can be recognized, for example a
“product-oriented structure”, a “function-oriented structure” or a “location-oriented structure”.
A specific constituent object may be of relevance in one structure only, or in more than one.
For further information on structures and structuring, see IEC 61346-1 and IEC 61346-4.
A parts list is implicitly or explicitly associated with such a structure. The parts list concept
described in this International Standard is therefore applicable in all structures defined in
accordance with IEC 61346-1.
Parts lists relevant to the physical manufacturing and assembly of a product, associated with
the product-oriented structure, usually cover only one assembly level each, and the main
assembly is normally described by a system of single-level parts lists. An example of a
system of single-level parts lists is shown in the figure below.
Parts lists are often generated as reports from a database containing information on the entire
structure.

3 Definitions
For the purpose of this International Standard, the following terms and definitions apply. In the
definitions, terms that are defined elsewhere in this clause are shown in italics.
3.1 General terms, related to structuring
3.1.1
object
entity treated in the process of design, engineering, realization, operation, maintenance and
demolition
NOTE 1 The entity may refer to a physical or non-physical "thing", or to a set of information associated with it.
NOTE 2 Depending on its purpose, an object may be viewed in different ways called "aspects".
[IEC 61346-1, definition 3.1]
3.1.2
system
set of interrelated objects
NOTE 1 Examples of a system: a drive system, a water supply system, a stereo system, a computer.
NOTE 2 When a system is part of another system, it may be considered as an object.
[IEC 61346-1, definition 3.2]
3.1.3
aspect
specific way of selecting information on or describing a system or an object of a system
NOTE Such ways may be:
– what the system or object does (function viewpoint);
– how the system or object is constructed (product viewpoint);
– where the system or object is located (location viewpoint).
[IEC 61346-1, definition 3.3]
---------------------- Page: 13 ----------------------

62027 © IEC:2000 – 15 –
3.1.4
structure
organization of relations among of a describing constituency-relations
objects system
(consists of/is a part of)
[IEC 61346-1, definition 3.6]
3.1.5
reference designation
identifier of a specific object with respect to the system of which the object is a constituent,
based on one or more of that
aspects system

3.1.6
item reference number
identification of component parts of assemblies and/or the identification of individual items on
the same drawing
[ISO 6433, clause 1]
NOTE Item reference numbers are “document-based” as opposed to reference designations that are “structure-
based”. Identical parts on a drawing are required to have the same item reference, preferably a number (according
to ISO 6433), while each occurrence of an object in a structure is required to have a unique reference designation
(according to IEC 61346-1).
If a set of drawings for a product is structurally based on consist-of/is-part-of relations, item reference numbers are
virtually the same thing as numeric product-oriented reference designations.
3.1.7
reference designation set
set of of which at least one unambiguously identifies the of
reference designations object
interest
NOTE Other members of the set need not necessarily identify the object of interest but other objects of which it is
a constituent.
[IEC 61346-1, definition 3.10]
3.1.8
transition (in a reference designation)
change of in a multi-level
aspect reference designation
[derived from IEC 61346-1]

document
information on a data medium
NOTE 1 The term document is not restricted to its meaning in a legal sense.
NOTE 2 Normally a document is designated in accordance with the type of information and the form of
presentation, for example overview diagram, connection table, function chart.
NOTE 3 Information may appear in a static manner on paper or microform, or dynamically on video display
devices.

4 General
4.1 Forms of presentation of a parts list
A parts list body is a tabular presentation of list items representing constituent objects.
The parts list body can be presented
– as a separate parts list document, or
– as a part of another document, for example the drawing presenting the assembled object
with which it is associated.
See Figure 1.

4.2 Table header
The table header defines the columns of the parts list body. A column may be used to present
one or more data element types.
4.3 List items
A list item in the parts list represents one constituent object and presents a selection of data
element types relevant to this. Every constituent object within the scope of the parts list is
represented by one list item; see also 3.3.3.
4.4 Classification of parts lists
The following classes of parts lists are recognized in this International Standard.
---------------------- Page: 16 ----------------------
SIST EN 62027:2002
62027 © IEC:2000 – 21 –
Class A
Parts lists in which each list item represents a type of constituent object and specifies the
quantity of this.
NOTE Class A deals with “summarized lists”; the quantity is often greater than one for each type, the part
number of each object may be used as a ‘key’. This class of parts list is referred to as a “bill-of-material (BOM)
data structure” in ISO 10303-44.
Class B
Parts lists in which each list item represents an occurrence of a constituent object.
NOTE Class B deals with "detailed lists"; the quantity is in principle equal to one in each list item, the
reference designation for the constituent object may be used as a ‘key’. This class of parts list is referred to as
“parts list data structure” in ISO 10303-44.
In cases where there is a need to specify a set of several identical objects, and if there is no need to
distinguish between them in any context in the documentation, this set may be treated as one occurrence, in
which the specified quantity is larger than one. Example: the hundreds of light-emitting diodes assembled to
form a traffic signal.
Class A parts lists are commonly used in mechanical design of discrete objects, especially if
only one structural level is covered by the parts list.
Class B parts lists are commonly used for electrical, fluid and other comprehensive systems,
where there is a need to identify each occurrence of a type, for example for connection
purposes.
In this International Standard, requirements for both classes are specified.
5 Requirements for the parts list body
5.1 Relation to the specified object
Any document in design and engineering, including parts lists, should be related to one
object.
The parts list shall specify the constituent objects of that object. Each constituent object is
specified by means of a list item.
A parts list may cover one structural level only or one level together with one or more lower
levels.
NOTE 1 For further information on the concept “object”, see IEC 61346-1 and IEC 61346-4.
NOTE 2 For further information on the relation of "objects" to associated documents and documentation, see also
IEC 61355 and IEC 62023.
NOTE 3 Parts lists covering more than one structural level are referred to as “indented
