ISO (the International Organization for Standardization) is a worldwide federation of national standards
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 technical 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.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types

Introduction
The ISO 15926 series provides a 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.
The ISO 15926 series is a series of parts, each published separately. This document specifies the core set of
reference data items. This document is a taxonomy of classes, and of properties which are unrelated to each
other. This document also contains non-plant classes (e.g. activity classes, milestones, statuses).
The reference data in this document have been developed since 1990 from the experience of operators,
contractors and equipment suppliers operating in the plant engineering supply chain. The reference data
therefore largely cover process plants installed in the oil, gas, process and power industries. The reference
data can be extended though change requests (CRs) with data that have not yet been covered, such as specific
nuclear data and specific pulp and paper equipment data. Such CRs will be processed according to the ISO TC
184/SC4 procedure for maintenance of reference data. In this procedure, the ISO/TS 15926-6 reference data
are checked against the technical rules given in ISO/TS 15926-6.

Core reference data
1 Scope
This document specifies the set of core reference data items which can be used to record information about
process plants, including oil and gas production facilities.
The following are within the scope of this document:
— core classes for process plants, including oil and gas production facilities;
— information about a reference data item.
NOTE The total set of information about a reference data item can be found in Table B.1.
The following are outside the scope of this document:
— data requirements for additional reference data items;
— the procedures to be followed for registration and maintenance of additional reference data items.
2 Normative references
The following documents are referred to in the text in such a way that some or all of their content constitutes
requirements of this document. For dated references, only the edition cited applies. For undated references,
the latest edition of the referenced document (including any amendments) applies.

3.1 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
ISO and IEC maintain terminology databases for use in standardization at the following addresses:
— ISO Online browsing platform: available at https:// www .iso .org/ obp
— IEC Electropedia: available at https:// www .electropedia .org/
3.1.1
class
category or division of things based on one or more criteria for inclusion and exclusion
Note 1 to entry: A class need not have any members (things that satisfy its criteria for membership).
Note 2 to entry: Because the spatio-temporal paradigm is used to define individuals in this document, all classes are
non-well-founded sets. These are explained in ISO 15926-2:2003, D.2.4.
[SOURCE: ISO 15926-1:2004, 3.1.1, modified — editorial updates to Note 2 to entry.]
3.1.2
commodity product class
manufactured product class that has sufficient characterization to indicate suitability for a defined use, and
that is an open agreed standard
Note 1 to entry: Often a commodity product class is defined by several other standards. A piping component typically
conforms to a “shape standard” and a “material standard”.
Note 2 to entry: Different manufactured product classes, which are specializations of the same commodity product
class, are interchangeable for the usage defined by the commodity product class.
Note 3 to entry: Adapted from ISO 15926-1:2004, 3.1.2.
EXAMPLE The type of light bulb known as 60 W 230 V E27 is a commodity class.
3.1.3
core class
class that is a commonly used subdivision corresponding to terms used in common language
EXAMPLE Pipe, floor, pump, and light bulb are all core classes.
[SOURCE: ISO 15926-1:2004, 3.1.4, modified — Note 1 to entry was deleted.]
3.1.4
data
representation of information in a formal manner suitable for communication, interpretation, or processing
by human beings or computers
[SOURCE: ISO 10303-2:2024, 3.1.207]
3.1.5
de facto class
class corresponding to common natures that are widely recognized but not formally agreed or defined
Note 1 to entry: De facto classes can be subsequently formalized by international, national, or industry agreement.
Note 2 to entry: A manufacturer can 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 USB port and HB pencil are de facto classes.
[SOURCE: ISO 15926-1:2004, 3.1.8, modified — Editorial update to Note 1 to entry, EXAMPLE 1 changed to

Introduction
The ISO 15926 is an International Standard forseries provides 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.
The ISO 15926 series is organized as a series of parts, each published separately. This part of ISO
15926document specifies the core set of reference data items.
The ISO 15926-4 reference data in this document have been developed since 1990 from the experience
of operators, contractors and equipment suppliers operating in the plant engineering supply chain. The
reference data therefore largely cover process plants installed in the oil, gas, process and power industry.
industries. The reference data can be extended though change requests (CRCRs) with data that have not
yet been covered, such as specific nuclear data and specific pulp and paper equipment data. Such CR’sCRs
will be processed in anaccording to the ISO verificationTC 184/SC4 N2591 procedure using agreed rules
fromfor maintenance of reference data. In this procedure, the ISO/TS 15926-6. reference data are
checked against the technical rules given in ISO/TS 15926-6.

Industrial automation systems and integration — Integration of
life-cycle data for process plants including oil and gas production
facilities — Part 4: Core reference data
1 Scope
This document specifies the set of core reference data items which can be used to record information
about process plants, including oil and gas production facilities.
The following are within the scope of this document:
— core classes for process plants, including oil and gas production facilities;
— information about a reference data item.
EXAMPLE 1 The unique name of a reference data item is information about that reference data item.
EXAMPLE 2 The definition of a reference data item is information about that reference data item.
NOTE The total set of information about a reference data item can be found in Table B.1.
The following are outside the scope of this document:
— data requirements for additional reference data items;
— the procedures to be followed for registration and maintenance of additional reference data items.

class
category or division of things based on one or more criteria for inclusion and exclusion
Note 1 to entry: A class need not have any members (things that satisfy its criteria for membership).
Note 2 to entry: Because the spatio-temporal paradigm is used to define individuals in this document, all classes are
non-well-founded sets. These are explained in ISO 15926-2:2003, D.2.4.
