ISO/TS 15926-6:2013(E)
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.
This part of ISO 15926 specifies the information that is required to be recorded for reference data items.
This part of ISO 15926 contains examples of reference data items.
NOTE 1 These examples are not taken from ISO/TS 15926-4 or from any other standard. In some cases, the
examples contain deliberate mistakes in order to show changes to a reference data library.
NOTE 2 A reference data library used with the ISO 15926 series of parts can be standardized or proprietary. A
reference data library which is initially proprietary can subsequently be submitted for standardization. Classes
contained within a reference data library can be more or less generic. Generic core classes and commodity classes
are likely to be standardized, but specific manufactured product classes are unlikely to be standardized. The
terms for the different types of class are defined in Clause 3.

series of parts.
The following are within the scope of this part of ISO 15926:
— identification of a reference data item;
— information that defines a reference data item;
— administrative information about the source, the history of changes, and current status of a
reference data and a reference data library;
— the way identification, defining information, and administrative data are recorded using ISO 15926-2;
— the reference data library that contains the reference data items necessary to record identification,
defining information, and administrative data;
— the representation of the reference data library that is defined by this part of ISO 15926 as a spreadsheet;
— requirements for the representation of a reference data library.
The following are outside the scope of this part of ISO 15926:
— the definitions of the scope of reference data libraries within the ISO 15926 series of standards;
— methods and guidelines for implementing ISO 15926-2;
— the representation of a reference data library, that is not defined by this part of ISO 15926;

and basic attributes
ISO 80000-1, Quantities and units — Part 1: General
1)
IETF RFC 2141, URN syntax
3 Terms, definitions, abbreviated terms and symbols
3.1 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1.1
administered item
registered item for which administrative information is recorded
[SOURCE: ISO/IEC 11179-3:2013, 3.2.2]
3.1.2
administrative information
information about the administration of an item in a metadata registry
[SOURCE: ISO/IEC 11179-3:2013, 3.2.3]
3.1.3
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 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.
[SOURCE: ISO 15926-1:2004, 3.1.1]
3.1.4
commodity product class
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 use defined by the commodity product class.
EXAMPLE The type of light bulb known as 60 W 230 V E27 is a commodity class.
[SOURCE: ISO 15926-1:2004, 3.1.2, modified]
3.1.5
core class
class that is a commonly used subdivision corresponding to terms used in common language
Note 1 to entry: 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.

3.1.6
data
representation of information in a formal manner suitable for communication, interpretation, or
processing by human beings or computers
[SOURCE: ISO 10303-1:1994, 3.2.14]
3.1.7
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 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.
[SOURCE: ISO 15926-1:2004, 3.1.8]
3.1.8
information
facts, concepts, or instructions
[SOURCE: ISO 10303-1:1994, 3.2.20]
3.1.9
ISO 15926 conforming reference data library
ISO 15926 reference data library that conforms to the requirements of ISO/TS 15926-6
Note 1 to entry: An ISO 15926 reference data library can, but need not, conform to the requirements of
ISO/TS 15926-6.
Note 2 to entry: An ISO 15926 reference data library can, but need not, be a standard.
3.1.10
ISO 15926 reference data library
reference data library that is recorded as instances of entities in ISO 15926-2
3.1.11
manufactured product class
class whose members are individuals produced by a manufacturing process
Note 1 to entry: The members of a manufactured product class may be discrete or may be batches or continuous
flows, such as process fluids.
EXAMPLE 1 “Light bulb 60 W 230 V E27” is an example of a manufactured product class whose members
are discrete.
EXAMPLE 2 “BS 4040 Leaded Petrol” is an example of a manufactured product class whose members are continuous.
Note 2 to entry: 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.

---------------------- Page: 9 ----------------------
ISO/TS 15926-6:2013(E)
3.1.12
physical quantity
property
aspect or quality of something that can be determined by measurement
Note 1 to entry: The term “property” is used in ISO 15926-2.
3.1.13
possible individual
thing that exists in space and time
Note 1 to entry: This definition is adapted from ISO 15926-2, within which “possible individual” is an entity, but
not a defined term.
3.1.14
proprietary class
class whose specification for membership is owned, controlled, or protected by an organization and is
not generally available outside that organization
[SOURCE: ISO 15926-1:2004, 3.1.16]
3.1.15
proprietary product class
class that is a manufactured product class and a proprietary class
Note 1 to entry: 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 Light bulbs 60 W 230 V E27 manufactured by Phillips are members of a proprietary product class.
[SOURCE: ISO 15926-1:2004, 3.1.17]
3.1.16
reference data
process plant life-cycle data that represents information about classes or individuals which are common
to many process plants or of interest to many users
[SOURCE: ISO 15926-1:2004, 3.1.18]
3.1.17
reference data item
thing that is defined within a reference data library
Note 1 to entry: Each reference data item is an administered item.
3.1.18
reference data item definition by text
text, and optionally equations and figures, that is intended to be understood by a person, and that is the
normative definition of a reference data item
3.1.19
reference data item definition by document reference
normative reference to a document that provides the normative definition of a reference data item
3.1.20
reference data item library record
reference data item and a set of statements about it within a reference data library
4 © ISO 2013 – All rights reserved
---------------------- Page: 10 ----------------------
ISO/TS 15926-6:2013(E)
3.1.21
reference data item non-person-interpretable identifier
text that is a unique identifier for a reference data item and that is not intended to be interpreted by a person
Note 1 to entry: The use of a reference data item non-person-interpretable identifier is defined in 5.2.
3.1.22
reference data item person-interpretable identifier
text that is a unique identifier for a reference data item, and that is intended to be interpreted by a person
Note 1 to entry: The use of a reference data item person-interpretable identifier is defined in 5.3.
Note 2 to entry: If a reference data item is a class, then its reference data item person-interpretable identifier
may be a term.
Note 3 to entry: The reference data item person-interpretable identifier is used for all references to a reference
data item in natural language text definitions.
Note 4 to entry: Names in natural language and terms in dictionaries are often unique only within a context. A
reference data item may be used in many contexts. Hence a reference data item person-interpretable identifier
may be longer than a name in a natural language, and contain words which qualify a natural language name, to
ensure that it is unique.
Note 5 to entry: A reference data library may contain additional terms for a reference data item, which are not
unique and which are used within particular contexts.
3.1.23
reference data library
managed collection of reference data
[SOURCE: ISO 15926-1:2004, 3.1.19]
3.1.24
standard class
class whose specification for membership is owned or controlled by a standardization body and is
publicly available
Note 1 to entry: 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 ASME B16.9 constrains the dimensions and shapes of steel butt welding pipe fittings.
EXAMPLE 2 IEC 60079–1 specifies constraints on electrical equipment to ensure standard degrees of
explosion proofness.
[SOURCE: ISO 15926-1:2004, 3.1.20]
3.1.25
statement
fact
information that is regarded as indivisible
Note 1 to entry: A statement can be recorded as an instance of the entity relationship in ISO 15926-2. A set of one
or more statements can be recorded in shorthand form as a single item as an instance of a template, as defined in
ISO/TS 15926-7.
3.1.26
thing
actual part of the real world, perceived part of the real world, or subject of thought
Note 1 to entry: A thing can be a material or non-material object, idea or action.
© ISO 2013 – All rights reserved 5
---------------------- Page: 11 ----------------------
ISO/TS 15926-6:2013(E)
Note 2 to entry: This definition is adapted from ISO 15926-2, within which “thing” is an entity, but not a defined term.
3.1.27
version of a reference data library
defined content from within a reference data library
Note 1 to entry: The content of a reference data library can change. A version of a reference data library cannot change.
Note 2 to entry: The formal definition of the class version of a reference data library in this part of ISO 15926 is
“multidimensional object that is a set of things and a set of statements about the set of things, where the things
and the statements are within a reference data library”.

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.
This part of ISO 15926 specifies the information that is required to be recorded for reference data items.
This part of ISO 15926 contains examples of reference data items.
NOTE 1 These examples are not taken from ISO/TS 15926-4 or from any other standard. In some cases, the
examples contain deliberate mistakes in order to show changes to a reference data library.
NOTE 2 A reference data library used with the ISO 15926 series of parts can be standardized or proprietary. A
reference data library which is initially proprietary can subsequently be submitted for standardization. Classes
contained within a reference data library can be more or less generic. Generic core classes and commodity classes
are likely to be standardized, but specific manufactured product classes are unlikely to be standardized. The
terms for the different types of class are defined in Clause 3.

3 Terms, definitions, abbreviated terms and symbols
3.1 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1.1
administered item
registered item for which administrative information is recorded
[SOURCE: ISO/IEC 11179-3:2013, 3.2.2]
3.1.2
administrative information
information about the administration of an item in a metadata registry
[SOURCE: ISO/IEC 11179-3:2013, 3.2.3]
3.1.3
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 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.
[SOURCE: ISO 15926-1:2004, 3.1.1]
3.1.4
commodity product class
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 use defined by the commodity product class.
EXAMPLE The type of light bulb known as 60 W 230 V E27 is a commodity class.
[SOURCE: ISO 15926-1:2004, 3.1.2, modified]
3.1.5
core class
class that is a commonly used subdivision corresponding to terms used in common language
Note 1 to entry: 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.

3.1.7
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 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.
[SOURCE: ISO 15926-1:2004, 3.1.8]
3.1.8
information
facts, concepts, or instructions
[SOURCE: ISO 10303-1:1994, 3.2.20]
3.1.9
ISO 15926 conforming reference data library
ISO 15926 reference data library that conforms to the requirements of ISO/TS 15926-6
Note 1 to entry: An ISO 15926 reference data library can, but need not, conform to the requirements of
ISO/TS 15926-6.
Note 2 to entry: An ISO 15926 reference data library can, but need not, be a standard.
3.1.10
ISO 15926 reference data library
reference data library that is recorded as instances of entities in ISO 15926-2
3.1.11
manufactured product class
class whose members are individuals produced by a manufacturing process
Note 1 to entry: The members of a manufactured product class may be discrete or may be batches or continuous
flows, such as process fluids.
EXAMPLE 1 “Light bulb 60 W 230 V E27” is an example of a manufactured product class whose members
are discrete.
EXAMPLE 2 “BS 4040 Leaded Petrol” is an example of a manufactured product class whose members are continuous.
Note 2 to entry: 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.

3.1.12
physical quantity
property
aspect or quality of something that can be determined by measurement
Note 1 to entry: The term “property” is used in ISO 15926-2.
3.1.13
possible individual
thing that exists in space and time
Note 1 to entry: This definition is adapted from ISO 15926-2, within which “possible individual” is an entity, but
not a defined term.
3.1.14
proprietary class
class whose specification for membership is owned, controlled, or protected by an organization and is
not generally available outside that organization
[SOURCE: ISO 15926-1:2004, 3.1.16]
3.1.15
proprietary product class
class that is a manufactured product class and a proprietary class
Note 1 to entry: 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 Light bulbs 60 W 230 V E27 manufactured by Phillips are members of a proprietary product class.

3.1.16
reference data
process plant life-cycle data that represents information about classes or individuals which are common
to many process plants or of interest to many users
[SOURCE: ISO 15926-1:2004, 3.1.18]
3.1.17
reference data item
thing that is defined within a reference data library
Note 1 to entry: Each reference data item is an administered item.
3.1.18
reference data item definition by text
text, and optionally equations and figures, that is intended to be understood by a person, and that is the
normative definition of a reference data item
3.1.19
reference data item definition by document reference
normative reference to a document that provides the normative definition of a reference data item
3.1.20
reference data item library record
reference data item and a set of statements about it within a reference data library

ISO/TS 15926-6:2013(E)
3.1.21
reference data item non-person-interpretable identifier
text that is a unique identifier for a reference data item and that is not intended to be interpreted by a person
Note 1 to entry: The use of a reference data item non-person-interpretable identifier is defined in 5.2.
3.1.22
reference data item person-interpretable identifier
text that is a unique identifier for a reference data item, and that is intended to be interpreted by a person
Note 1 to entry: The use of a reference data item person-interpretable identifier is defined in 5.3.
Note 2 to entry: If a reference data item is a class, then its reference data item person-interpretable identifier
may be a term.
Note 3 to entry: The reference data item person-interpretable identifier is used for all references to a reference
data item in natural language text definitions.
Note 4 to entry: Names in natural language and terms in dictionaries are often unique only within a context. A
reference data item may be used in many contexts. Hence a reference data item person-interpretable identifier
may be longer than a name in a natural language, and contain words which qualify a natural language name, to
ensure that it is unique.
Note 5 to entry: A reference data library may contain additional terms for a reference data item, which are not
unique and which are used within particular contexts.
3.1.23
reference data library
managed collection of reference data
[SOURCE: ISO 15926-1:2004, 3.1.19]
3.1.24
standard class
class whose specification for membership is owned or controlled by a standardization body and is
publicly available
Note 1 to entry: 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 ASME B16.9 constrains the dimensions and shapes of steel butt welding pipe fittings.
EXAMPLE 2 IEC 60079–1 specifies constraints on electrical equipment to ensure standard degrees of
explosion proofness.
[SOURCE: ISO 15926-1:2004, 3.1.20]
3.1.25
statement
fact
information that is regarded as indivisible
Note 1 to entry: A statement can be recorded as an instance of the entity relationship in ISO 15926-2. A set of one
or more statements can be recorded in shorthand form as a single item as an instance of a template, as defined in
ISO/TS 15926-7.
3.1.26
thing
actual part of the real world, perceived part of the real world, or subject of thought
Note 1 to entry: A thing can be a material or non-material object, idea or action.

3.1.27
version of a reference data library
defined content from within a reference data library
Note 1 to entry: The content of a reference data library can change. A version of a reference data library cannot change.
Note 2 to entry: The formal definition of the class version of a reference data library in this part of ISO 15926 is
“multidimensional object that is a set of things and a set of statements about the set of things, where the things
and the statements are within a reference data library”.

4.1 A reference data item
A reference data item shall be an instance of an entity defined in ISO 15926-2.
NOTE 1 A reference data item is often an instance of class, but can be an instance of another type of abstract
object, or of possible individual.
NOTE 2 A reference data item can be an instance of a template as defined in ISO/TS 15926-7, because a template
is an instance of class of relationship which is defined in ISO/IEC 15026-2.
