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.

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.

3.1.3

core class

class that is a commonly used subdivision corresponding to terms used in common language

[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.

[SOURCE:ISO 15926-1:2004, 3.1.8, modified — Editorial update to Note 1 to entry, EXAMPLE 1 changed to Note 2 to entry and updated, EXAMPLE 2 is now EXAMPLE and updated.]

3.1.6

information

facts, concepts, or instructions

[SOURCE:ISO 10303-1:2021, 3.1.41, modified — Examples 1 and 2 added.]

3.1.7

manufactured product class

class whose members are individuals produced by a manufacturing process

Note 1 to entry: The members of a manufactured product class can be discrete, or can be batches or continuous flows, such as process fluids.

Note 2 to entry: A manufactured product class may correspond to a specification that has not been realized, such product specification for which no products have been made.

[SOURCE:ISO 15926-1:2004, 3.1.14, modified — Editorial update to Note 1 to entry, example updated]

3.1.8

product class

artefact that has been designed by a manufacturer and whose members may fulfil the requirements set forth in an instance of an asset requirement class

3.1.9

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]

3.1.10

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 ここで, the additional restrictions reflect design or manufacturing details that the manufacturer uses to differentiate its product from others of the same general type.

3.1.11

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]

3.1.12

reference data item

thing that is defined within a reference data library

Note 1 to entry: Each reference data item is an administered item.

Note 2 to entry: A registration authority can regard a reference data item as an administered item as defined in ISO/IEC 11179-6.

3.1.13

reference data library

managed collection of reference data items

[SOURCE:ISO 15926-1:2004, 3.1.19, —"items" added to definition.]

3.1.14

reference data library module

collection of reference data items within a reference data library that shares the same subject area

3.1.15

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 need only constrain one particular aspect and can often be insufficient to determine usage or be a full manufacturing specification.
