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 (3.1.7) whose members conform to open agreed standards

Note 1 to entry: Commodity product classes have sufficient characterization to indicate suitability of use. They are specializations of one or more de facto classes (3.1.5) , standard classes (3.1.12) , or both. The resulting specification is non-proprietary, as no one organization controls it.

[SOURCE: ISO 15926-1:2004, 3.1.2]

3.1.3

core class

class (3.1.1) 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, so understanding of the class may be conveyed by example.

[SOURCE: ISO 15926-1:2004, 3.1.4]

3.1.4

data

representation of information (3.1.6) in a formal manner suitable for communication, interpretation, or processing by human beings or computers

[SOURCE: ISO 10303-1:1994, 3.2.14]

3.1.5

de facto class

class (3.1.1) 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.

3.1.6

information

facts, concepts, or instructions

[SOURCE: ISO 10303-1:1994, 3.2.20]

3.1.7

manufactured product class

class (3.1.1) 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 as a product specification for which no products have been made.

3.1.8

proprietary class

class (3.1.1) 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]

3.1.9

proprietary product class

class (3.1.1) that is a manufactured product class (3.1.7) and a proprietary class (3.1.8)

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 (3.1.2) , de facto classes (3.1.5) , 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.

3.1.10

reference data item

reference data

process plant life-cycle data (3.1.4) that represents information (3.1.6) about classes (3.1.1) or individuals which are common to many process plants or of interest to many users

Note 1 to entry: A registration authority can regard a reference data item as an administered item as defined in ISO/IEC 11179-6.

[SOURCE: ISO 15926-1:2004, 3.1.18, modified — The word “item” has been added to the preferred term to remove ambiguity between singular and plural, and Note 1 to entry has been added.]

3.1.11

reference data library

managed collection of reference data items (3.1.10)

[SOURCE: ISO 15926-1:2004, 3.1.19, modified — The abbreviated term “RDL” has been removed and the word “items” has been added to the definition to remove ambiguity between singular and plural.]

3.1.12

standard class

class (3.1.1) 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.
