Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national stan-
dards bodies (ISO member bodies). The work of preparing International Standards is normally carried
out through ISO technical committees. Each member body interested in a subject for which a techni-
cal committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives,
Part 2.
The main task of technical committees is to prepare International Standards. Draft International Stan-
dards adopted by the technical committees are circulated to the member bodies for voting. Publication
as an International Standard requires approval by at least 75% of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 15926-1 was prepared by Technical Committee ISO/TC184, Industrial automation systems and
integration, Subcommittee SC4, Industrial data.
ISO 15926 consists of the following parts, under the general title Industrial automation systems and
integration — Integration of life-cycle data for process plants including oil and gas production facili-
ties:

0 Introduction
0.1 Background
Information concerning the engineering, construction and operation of process plants is created, used
and modified by many different organizations throughout a plant’s life. Economic, safety and envi-
ronmental considerations demand that this information is available to owners and operators of facili-
ties, contractors, and regulatory bodies in a consistent, integrated form. This requirement can be satis-
fied by specifications that prescribe the structure and meaning of data that is shared by organizations
and disciplines involved in all stages of a plant’s life-cycle.
The need to increase the cost efficiency of process plants is leading to business practices that depend
on the efficient integration and sharing of plant information in a computer processable form. These
business practices include the following.
— Many users’ needs now span more than one of the traditional information views. Safety and envi-
ronment are two examples of this.
— Concurrent engineering requires design work to progress in parallel, with the state of the design
being available electronically, in computer processable form, to other engineering, planning, pur-
chasing and logistical activities.
— Significant cost savings are expected from standardization of component specifications. The in-
formation about these specifications is required in computer processable form for easy incorpora-
tion into plant designs and requirements.
— In the past, hand-over of plant design information was often restricted to design drawings and pa-
per documents. Use of this information in managing the operation and modification of the plant
was restricted to manual processes, or the information had to be redefined in a format suitable to
the required application. Having the plant design and equipment information in computer proc-
essable form increases the efficiency and effectiveness of the operational phase of the plant.
— Accurate computer processable information about a plant’s performance throughout its lifetime is
of high value, for optimising future modifications to the plant and for designing new plants on the
basis of experience with existing plants.
By using a consistent context for data definitions, the information used in the various aspects of the
plant’s life-cycle can be brought together. This allows information to be integrated, shared and ex-
changed in a consistent, computer processable form.
0.2 Purpose of ISO 15926
The purpose of this International Standard is to facilitate integration of data to support the life-cycle
activities and processes of process plants. To do this, this International Standard specifies a data
model that defines the meaning of the life-cycle information in a single context supporting all the
views that process engineers, equipment engineers, operators, maintenance engineers and other spe-
cialists may have of the plant.
Traditionally, data associated with a process plant have been concentrated on some individual view of
the plant at a point in time. Such data are usually defined and maintained independently of other
groups of users, resulting in duplicated and conflicting data that cannot be shared either within an en-
terprise or with business partners of an enterprise.

ISO 15926-1:2004(E)
0.3 Description of ISO 15926
ISO 15926 is an International Standard for the representation of process plant life-cycle information.
This representation is specified by a generic, conceptual data model that is suitable as the basis for
implementation in a shared database or data warehouse. The data model is designed to be used in con-
junction with reference data, i.e. standard instances that represent information common to a number of
users, process plants, or both. The support for a specific life-cycle activity depends on the use of ap-
propriate reference data in conjunction with the data model.
ISO 15926 is organized as a series of parts, each published separately. This part of ISO 15926 pro-
vides an overview. It specifies the contents and functions of the different parts of ISO 15926 and the
relationships between them, and describes:
— an overview of ISO 15926;
— the fundamental principles that are the basis of ISO 15926;
— the relationship of ISO 15926 to other industrial data standards;
— definitions of terms used throughout ISO 15926.
0.4 Typographical conventions
The following typographical conventions are used in this International Standard.
A numbered reference enclosed in brackets (for example, “[2]”) is a reference to a document that is
listed in the Bibliography.
In this International Standard the same English language words may be used to refer to an object in
the real world or to a concept, and as the name of an EXPRESS data type that represents this object or
concept. The following typographical convention is used to distinguish between these. If a word or
phrase occurs in the same typeface as narrative text, the referent is the object or concept. If the word
or phrase occurs in a bold typeface, the referent is the EXPRESS data type. Names of EXPRESS
schemas also occur in a bold typeface.
The name of an EXPRESS data type may be used to refer to the data type itself, or to an instance of
the data type. The distinction between these uses is normally clear from the context. If there is a like-
lihood of ambiguity, the phrase “entity data type” or “instance(s) of” is included in the text.
Double quotation marks “ ” denote quoted text. Single quotation marks ‘ ’ denote particular text string
values.
Some components of this International Standard are available in electronic form. This access is pro-
vided through the specification of Universal Resource Locators (URLs) that identify the location of
these files on the Internet. If there is difficulty accessing these files contact the ISO Central Secre-
tariat, or contact the ISO TC 184/SC4 Secretariat directly at: sc4sec@tc184-sc4.org.

INTERNATIONAL STANDARD ISO 15926-1:2004(E)
Industrial automation systems and integration —
Integration of life-cycle data for process plants including
oil and gas production facilities —
Part 1:
Overview and fundamental principles
1 Scope
This International Standard specifies a representation of information associated with engineering, con-
struction and operation of process plants. This representation supports:
— the information requirements of the process industries in all phases of a plant’s life-cycle;
NOTE 1 The process industries include those involved in oil and gas production, refining, power generation,
and manufacturing of chemicals, pharmaceuticals, and food.
— sharing and integration of information amongst all parties involved in the plant’s life-cycle.
The following are within the scope of ISO 15926:
— a generic, conceptual data model that supports representation of all life-cycle aspects of a process
plant;
— reference data that represents information common to many process plants and users;
— scope and information requirements for additional reference data;
— methods for the analysis of requirements and development of reference data;
— procedures for registration and maintenance of reference data;
— templates for the exchange of data used in a particular context and their mapping to the concep-
tual data model;
— methods for the development of such templates and their mapping to the conceptual data model;
— conformance to the requirements of this International Standard.
The scope of business activities that are supported by this International Standard is illustrated in
Figure 1, which shows the main activities and data flows associated with the life-cycle of a plant.
NOTE 2 Figure 1 is based on the Process Plant Engineering Activity Model [6].

NOTE 3 The support for a specific life-cycle activity depends on the use of appropriate reference data in con-
junction with the data model defined in ISO 15926-2.
EXAMPLE A reference data library covering technical data about process systems, electrical systems and
instrumentation systems can support design, engineering and maintenance activities for these systems within a
process plant.
The following are outside the scope of ISO 15926:
— commercial, business, and administrative data that are not directly related to the engineering,
operation and maintenance of process plants.
This International Standard is applicable to implementation of databases or data warehouses that en-
able integration and sharing of data amongst different participants in the life-cycle of a process plant.
The generic data model specified in ISO 15926-2 provides a suitable conceptual data model for such a
database or data warehouse.
NOTE 4 See 5.2 for further information concerning the nature of conceptual data models.
This part of ISO 15926 provides an overview of this International Standard. The scopes of the other
parts of ISO 15926 are defined within those parts.

3 Terms, definitions, and abbreviations
3.1 Terms and definitions
For the purposes of this part of ISO 15926, the following terms and definitions apply.
NOTE Definitions copied verbatim from other standards are followed by a reference to the standard in brack-
ets, such as “[ISO 10303-1]”. In these cases the definition in the referenced document is normative; its repeti-
tion here is informative and in the case of any discrepancy the definition in the referenced document has prece-
dence. An explanatory note follows definitions that have been adapted from other standards. In these cases the
definition given here is normative for the purposes of this part of ISO 15926.
3.1.1
class
category or division of things based on one or more criteria for inclusion and exclusion
NOTE 1 A class need not have any members (things that satisfy its criteria for membership).
NOTE 2 Because of the spatio-temporal paradigm used to define individuals in this International Standard, all
classes are non-well-founded sets. These are explained in ISO 15926-2:D.2.4
3.1.2
commodity product class
manufactured product class whose members conform to open agreed standards
NOTE Commodity product classes have sufficient characterisation to indicate suitability of use. They are
specializations of one or more de facto classes, standard classes, or both. The resulting specification is non pro-
prietary as no one organization controls it.
EXAMPLE The type of lightbulb known as 60 W 230 V E27 is a commodity product class.

ISO 15926-1:2004(E)
3.1.3
conceptual data model
data model in the three schema architecture defined by ISO/TR 9007, in which the structure of data is
represented in a form independent of any physical storage or external presentation format
NOTE Adapted from the IDEF1X specification [4].
3.1.4
core class
class that is a commonly used subdivision corresponding to terms used in common language
NOTE The conditions for membership are often not formally defined; understanding of the class may be
conveyed by example.
EXAMPLE Pipe, floor, pump, and light bulb are all core classes.
3.1.5
data
representation of information in a formal manner suitable for communication, interpretation, or proc-
essing by human beings or computers
[ISO 10303-1]
3.1.6
data store

3.1.7
data warehouse
data store in which related data are merged to provide an integrated set of data containing no
duplication or redundancy of information, and which supports many different application viewpoints
3.1.8
de facto class
class corresponding to common natures that are widely recognized but not formally agreed or defined
NOTE De facto classes may be formalized by international, national, or industry agreement.
EXAMPLE 1 A manufacturer may choose to make a product of similar specification to that of another
manufacturer in order to compete for the market share by choosing to conform to some characteristics of the
other product.
EXAMPLE 2 3.5” floppy disk and HB pencil are de facto classes.
3.1.9
exchange file
computer-interpretable format used for storing, accessing, transferring and archiving data
NOTE Adapted from the definition of “exchange structure” in ISO 10303-1.
3.1.10
implementation method
technique used by computer systems to exchange or access data that is described using the EXPRESS
data specification language
NOTE Adapted from ISO 10303-1.

---------------------- Page: 11 ----------------------
ISO 15926-1:2004(E)
3.1.11
individual
thing that exists in space and time
NOTE 1 In this context existence is based upon being imaginable within some consistent logic, including ac-
tual, hypothetical, planned, expected, or required individuals.
EXAMPLE A pump with serial number ABC123, Battersea Power Station, Sir Joseph Whitworth, and the
Starship “Enterprise” are examples of individuals.
NOTE 2 See ISO 15926-2, 4.7, for a detailed discussion of the concept of individuals.
3.1.12
information
facts, concepts, or instructions
[ISO 10303-1]
3.1.13
instance
data that represents, in computer processable form, some real-world thing
NOTE This is different from the ISO 10303-11 definition due to its use for reference and life-cycle data.
3.1.14
manufactured product class
class whose members are individuals produced by a manufacturing process
NOTE 1 The members of a manufactured product class may be discrete or may be batches or continuous flows,
such as process fluids.
EXAMPLE 1 “Lightbulbs 60 W 230 V E27” is an example of a manufactured product class whose members
are discrete.
EXAMPLE 2 “BS4040 Leaded Petrol” is an example of a manufactured product class whose members are
continuous.
NOTE 2 A manufactured product class may correspond to a specification that has not been realized, such a
product specification for which no products have been made.
3.1.15
process plant life-cycle data
data that represents, in computer processable form, information about one or more process plants in or
throughout any phases of their life
NOTE The phases of the life of a process plant may include design, engineering, construction, op-
eration, maintenance, decommissioning and demolition.
3.1.16
proprietary class
class whose specification for membership is owned, controlled, or protected by an organization and is
not generally available outside that organization
3.1.17
proprietary product class
class that is a manufactured product class and a proprietary class
© ISO 2004 – All rights reserved 5
---------------------- Page: 12 ----------------------
ISO 15926-1:2004(E)
NOTE Proprietary product classes are specializations that depend on rules of inclusion and exclusion some
of which are controlled in a closed way. This means that some aspects of the specification can be arbitrarily
changed. Many proprietary product classes are specializations of commodity product classes, de facto classes,
or both, where the additional restrictions reflect design or manufacturing details that the manufacturer uses to
differentiate his product from others of the same general type.
EXAMPLE 1 A product specification that is owned by a commercial organization, and is marketed under and
protected by a registered trade name, is the basis for a proprietary product class.
EXAMPLE 2 Lightbulbs 60 W 230 V E27 manufactured by Phillips are members of a proprietary product
class.
3.1.18
reference data
process plant life-cycle data that represents information about classes or individuals which are com-
mon to many process plants or of interest to many users
3.1.19 reference data library (RDL)
managed collection of reference data
3.1.20
standard class
class whose specification for membership is owned or controlled by a standardization body and is
publicly available
NOTE Standard classes result from the work of national, international, or industry standardization bodies and
cover sizes, shapes, materials, performance, and manufacturing processes of equipment and materials. The rules
for exclusion and inclusion (or conformance) are agreed by an open, consensus process and are made publicly
available. A standard class may only constrain one particular aspect and often be insufficient to determine usage
or full manufacturing specifications.
EXAMPLE 1 The ASME B16.9 standard [3] constrains the dimensions and shapes of steel buttwelding pipe
fittings.
EXAMPLE 2 The IEC 60079-1 [2] standard specifies constraints on electrical equipment to ensure standard
degrees of explosion proofness.
3.2 Abbreviations
For the purposes of this part of ISO 15926, the following abbreviations apply.

4 Overview of ISO 15926
ISO 15926 is divided into a number of parts. Each part has a unique function.
— ISO 15926-1 (this part) provides an overview of ISO 15926.
— ISO 15926-2 specifies a generic, conceptual data model that supports representation of all life-
cycle aspects of a process plant.
6 © ISO 2004 – All rights reserved
---------------------- Page: 13 ----------------------
ISO 15926-1:2004(E)
— ISO 15926-4 defines a reference data library that can be periodically updated by a competent
body, designated by ISO as a registration authority, which has the requisite infrastructure to en-
sure the effective use of the reference data library.
— ISO 15926-5 specifies the procedures to be followed by a registration authority for reference data.
— ISO 15926-6 specifies the information required when defining additions to the reference data
specified in ISO 15926-4.
5 Fundamental principles
5.1 Architecture
The architecture that underlies this International Standard is illustrated in Figure 2. The architecture is
an example of that described in ISO 18876-1. This International Standard supports integration over a
wide context due to the nature of the generic, conceptual data model that is its foundation. Process
plant life-cycle data is structured according to the data model defined in ISO 15926-2. This data is
divided into data about an individual process plant, and reference data, which represents information
that is common to many process plants or of interest to many users.
