A Specification is a characteristic of a product. A Specification discriminates one product from other members of the same Product_class. A Specification refers to a Specification_category that completes the semantics of the Specification.

NOTE 1 A Specification may be a characteristic of the members of more than one Product_class using Class_specification_association objects.

NOTE 2 A Specification in combination with a Configuration may be used to define under which conditions an Item is used for a product of a Product_class.

EXAMPLE 'coupe', 'hatch back', or 'sedan' are examples for specifications belonging to the Specification_category of type 'car body'. 'radio 1 with CD player' and 'radio 2 without CD player' are examples for specifications belonging to the Specification_category of type 'radio equipment'. 'disk brake' and 'drum brake' are examples for specifications belonging to the Specification_category of type 'braking system'.

The data associated with a Specification are the following:

4.2.488.1 category

The category specifies the Specification_category that completes the semantics of the Specification.

See specification to specification_category for the application assertion.

4.2.488.2 description
