NOTE 2 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. 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.

class that is a manufactured product class and a proprietary class [ISO 15926-1:2004, 3.1.17]

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 dif-ferentiate 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 Lightbulbs 60 W 230 V E27 manufactured by Phillips are members of a proprietary product class.

text, and optionally equations and figures, that is the normative definition of a concept within an RDL NOTE A RDL definition can be either intentional or extensional.

the text, equations and figures within an RDL that explain the nature of a concept to a person NOTE A RDL description can contain an RDL definition (xxx).

text that is the unique identifier for a concept within an RDL NOTE 1 If the identified concept is a class, then the RDL designation is a term. If the identified concept is an individual, then the RDL designation is an appellation. NOTE 2 The RDL designation is used for all references to a concept within normative text in ISO 15926-4. NOTE 3 Names in natural language and terms in dictionaries are often unique only within a context. An RDL may contain concepts from many contexts. Hence an RDL designation may be longer than a name in a natural language, and contain words that qualify a natural language name, to ensure that it is unique. NOTE 4 An RDL may contain additional terms for a concept, which are not unique and which are used within particular contexts.

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 [ISO 15926-1:2004, 3.1.18]

NOTE Corresponds to the concept that plays the role ‘superclass’ in a specialization relationship in ISO 15926-2:2003.

class whose specification for membership is owned or controlled by a standardization body and is publicly available [ISO 15926-1:2004, 3.1.20]

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.
