Application module: Class of composition of product | ISO/TS 10303-1158:2005(E) © ISO |
This clause specifies the information requirements for the Class of composition of product application module. The information requirements are specified as the Application Reference Model (ARM) of this application module.
NOTE 1 A graphical representation of the information requirements is given in Annex C.
NOTE 2 The mapping specification is specified in 5.1. It shows how the information requirements are met by using common resources and constructs defined or imported in the MIM schema of this application module.
The following EXPRESS specification begins the Class_of_composition_of_product_arm schema and identifies the necessary external references.

Class_arm ISO/TS 10303-1070 Class_of_product_arm ISO/TS 10303-1077 Product_version_relationship_arm ISO/TS 10303-1020
NOTE 2 See Annex C, Figures C.1and C.2 for a graphical representation of this schema.
This subclause specifies the ARM entity for this module. The ARM entity is an atomic element that embodies a unique application concept and contains attributes specifying the data elements of the entity. The ARM entity and definition is specified below.
A Class_of_composition_of_product specifies a composition mapping between classes of product.
The nature of a whole-part relationship between individual products may be specified by indicating a class of composition of which it is a member.
EXAMPLE 1 'Centrifugal pump' is a class of product. 'Impeller' is a class of product. The relationship between 'centrifugal pump' and 'impeller', that indicates a centrifugal pump has an impeller, is a class_of_composition_of_product.
EXAMPLE 2 Pump model XYZ_123 is a class of product. Impeller model I_123/A is a class of product. The relationship between pump model XYZ_123 and impeller model I_123/A, that indicates a pump model has an impeller of the type, is a class_of_composition_of_product.
At an instant in time, a pump of model XYZ_123 has 0 or 1 impeller of type I_123/A. An impeller of type I_123/A is a member of 0 or 1 pump of model XYZ_123.
NOTE 1 The cardinality for the relationship is within the scope of the Cardinality of relationship application module.
NOTE 2 This entity is identical to class_of_composition_of_individual in ISO 15926-2, where the relationship is between classes of product.
