4.2.416 Product_specification

A Product_specification is a Product_identification for which one or more additional Specification objects enhance the characterization provided for the associated Product_class.

NOTE 1 The actual set of Specification objects for a Product_specification are obtained by the union of 'defining_specifications' and of the Specification objects related to the 'associated_product_class' through a Class_specification_association or a Class_condition_association with association_type 'identification' or 'non replaceable standard'.

NOTE 2 The specification of a Product_specification may be incomplete: there may not be in 'defining_specification' any instance of Specification for some Specification_category declared as mandatory for the 'associated_product_class'. For these Specification_category objects any Specification available in the context of the 'associated_product_class' is considered as valid for the manufacturing of the product characterized by the considered Product_specification.

EXAMPLE If the colour is not specified for a given car family, the vehicle resulting from the realization of a Product_specification associated to the Product_class representing the car family may be without paint or painted in any available colour. A Product_specification is a type of Product_identification.

The data associated with a Product_specification are the following:

defining_specification

The defining_specification specifies the set of Specification objects necessary to discriminate the Product_specification within its Product_class.

Each defining_specification shall be associated with a Product_class by a Class_specification_association with association_type not equal 'part usage'. The associated Product_class shall be either the associated Product_class of the Product_specification or any higher level Product_class related directly or indirectly by a Product_class relationship with a relation_type 'hierarchy'.

See product_specification to specification for the application assertion.
