A Specification to define requirements for the handling of wire / wire element tuples (pairs, triple,...) with the focus on twisting. More precisely, the allowed untwisting at the wire ends and required measures against it.

This definition is made independent from the WireGroup, as the might be defined for the part master data (the wire on the roller). The specifications for untwisting are based on the concrete usage.

Name Type Mult. Description Owning Classifier
identification String 1

Specifies a unique identification of the specification. The identification is guaranteed to be unique within the document containing the specification. For all VEC-documents a Specification-instance can be trusted to be identical if the DocumentVersion-instance is the same (see DocumentVersion) and the identification of the Specification is the same.
