Application module: Functional data and schematic representation | ISO/TS 10303-421:2005(E) © ISO |
TECHNICAL SPECIFICATION | ISO/TS 10303-421:2005(E) |
This part of ISO 10303 specifies the application module Functional data and schematic representation. The following are within the scope of this part of ISO 10303:
the classification, structure, properties and identification of products, activities, documents, organisations and people;
The structure of products includes both composition and connection relationships. A composition relationship can be either physical or functional. Similarly a functional relationship can be either physical or functional. Types or classes of relationship are defined in a Reference Data Library. The type of a relationship indicates whether it is functional or physical.
EXAMPLE 1 'Bolted connection' is a class of connection that is physical. The connection between pipe segment 'S12' and the inlet nozzle of vessel 'V4506' is a connection of this class.
EXAMPLE 2 'Signal connection' is a class of connection that is functional. The connection between instrument signal line 'i1' and the flow instrument '45-FT-501' is a connection of this class.
NOTE 1 This capability is provided by the referenced Functional_data application module.
schematic diagrams that presents the classification, structure, properties and identification of products, activities, documents, organisations and people by the relative position of symbols;
NOTE 2 This capability is provided by the referenced Schematic_and_symbolization application module.
associations between symbols on a schematic diagram and the things that the symbols represent.
NOTE 3 This capability is provided by the referenced Schematic_and_symbolization application module.
NOTE 4 Application software can use the associations to make the schematic diagram 'intelligent'. This means that a user of the software can select a symbol on the diagram, and thereby obtain further information about the object that is represented.
The following are outside the scope of this part of ISO 10303:
shape and position of products;
the capabilities of application software that processes a schematic diagram.
