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 Electro technical Commission (IEC) on all matters of
electro technical 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.
In other circumstances, particularly when there is an urgent market requirement for such documents, a
technical committee may decide to publish other types of normative document:
— an ISO Publicly Available Specification (ISO/PAS) represents an agreement between techni-
cal experts in an ISO working group and is accepted for publication if it is approved by more
than 50% of the members of the parent committee casting a vote;
— an ISO Technical Specification (ISO/TS) represents an agreement between the members of a
technical committee and is accepted for publication if it is approved by 2/3 of the members of
the committee casting a vote.
An ISO/PAS or ISO/TS is reviewed every three years with a view to deciding whether it can be trans-
formed into an International Standard.
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/TS 15926-4 was prepared by Technical Committee ISO/TC 184, Industrial automation systems

Introduction
ISO 15926 is an International Standard for the representation of process industries facility 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 conjunction with reference data, i.e. standard instances that represent information common to
a number of users, production facilities, or both. The support for a specific life-cycle activity depends
on the use of appropriate 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 speci-
fies the initial set of reference data items.
The structure of ISO 15926 is as follows:
— ISO 15926-1 provides an overview of ISO 15926;
— ISO 15926-2 contains a generic, conceptual data model that supports representation of all life-
cycle aspects of a process plant;
1
contains a reference data library for geometry and topology;
— ISO/TS 15926-3
— ISO/TS 15926-4 contains a reference data library for physical objects, activities, properties and
other reference data necessary to record information about a process plant;
2
— ISO 15926-5 specifies the procedures to be followed for the maintenance of the reference data
library ISO/TS 15926-4;
3
— ISO 15926-6 specifies the information that is recorded for reference data items of ISO/TS 15926-4;
4
— ISO/TS 15926-7 specifies implementation methods for the integration of distributed systems.

TECHNICAL SPECIFICATION ISO/TS 15926-4:2007(E)
Industrial automation systems and integration — Integration
of life-cycle data for process plants including oil and gas
production facilities —
Part 4:
Initial reference data
1 Scope
This part of ISO 15926 specifies the initial set of core reference data items which can be used to re-
cord information about process plants, including oil and gas production facilities.
The following are within the scope of this part of ISO 15926:
— core classes for process plants, including oil and gas production facilities;
NOTE 1 Reference data items can be core classes, de facto classes, commodity classes and manufac-
tured product classes. Reference data items can also be standard classes or proprietary classes.
The terms for the different types of class are defined in 3.2. A discussion about the different types
of classes is contained in Annex D.
— the unique name for each reference data item;
— the definition of each reference data item;
— subclass and classification relationships between reference data items;
NOTE 2 Each reference data item that is a class is directly or indirectly a subclass of an entity
in ISO 15926-2.
— the entity within ISO 15926-2 which can be used to record each reference data item.
The following are outside the scope of this part of ISO 15926:
— data requirements for additional reference data;
— a numeric identifier for each reference data item;
NOTE 3 Numeric identifiers may be assigned by a registration authority.
— the procedures to be followed for registration and maintenance of additional reference data.
NOTE 4 A core class defined by this part of ISO 15926 can be used by ISO 15726-2, ISO/TS 15926-7 or
ISO 10303-221.

3 Terms, definitions, and abbreviations
3.1 Terms defined in ISO 10303-1
For the purposes of this document, the following terms and definitions given in ISO 10303-1 apply.
They are repeated below for convenience.
3.1.1
data
representation of information in a formal manner suitable for communication, interpretation, or proc-
essing by human beings or computers
3.1.2
information
facts, concepts, or instructions
3.2 Terms defined in ISO 15926-1
For the purposes of this document, the following terms and definitions given in ISO 15926-1 apply.
They are repeated below for convenience.
3.2.1
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 the spatio-temporal paradigm is used to define individuals in this part of ISO 15926, all
classes are non-well-founded sets. These are explained in ISO 15926-2:2003, D.2.4
3.2.2
commodity product class
manufactured product class whose members conform to open agreed standards
2 © ISO 2007 – All rights reserved
---------------------- Page: 8 ----------------------
ISO/TS 15926-4:2007(E)
NOTE Commodity product classes have sufficient characterization to indicate suitability of use. They are
specializations of one or more de facto classes, standard classes, or both. The resulting specification is non-
proprietary, as no one organization controls it.
EXAMPLE The type of light bulb known as 60 W 230 V E27 is a commodity class.
3.2.3
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.
3.2.4
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.
3.2.5
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.
NOTE 2 A manufactured product class may correspond to a specification that has not been realized, such as
a product specification for which no products have been made.
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.
3.2.6
proprietary class
class whose specification for membership is owned, controlled, or protected by an organization and is
not generally available outside that organization
3.2.7
proprietary product class
class that is a manufactured product class and a proprietary class
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.

---------------------- Page: 9 ----------------------
ISO/TS 15926-4:2007(E)
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.
3.2.8
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
3.2.9 reference data library (RDL)
managed collection of reference data
3.2.10
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 constrains the dimensions and shapes of steel buttwelding pipe
fittings.
EXAMPLE 2 The IEC 60079-1 standard specifies constraints on electrical equipment to ensure standard
degrees of explosion proofness.
3.3 Other terms and definitions
For the purposes of this document, the following terms and definition apply.
3.3.1
reference data item
thing that is defined within a reference data library
NOTE A registration authority may regard a reference data item as an administered item as defined in
ISO/IEC 11179-6.
3.4 Abbreviated terms
For the purposes of this document, the following abbreviated terms apply.
