Provides a common formal model for the IEC 61360-1 and ISO 13584-42 and facilitates their harmonization. Allows for the implementation of dictionary systems dealing with data delivered according to either of those standards.Provides a formal model for data according to the scope as given in the publications cited above, and thus provides a means for the computer-sensible representation and…

Is divided into three sections, each dealing with specific examples of standardized dimensions. Section I: Fuse-links having bolted connections: Type A, Type B, Type C. Section II: Fuse-links with flush end connections: Type A, Type B. Section III: Fuse-links with cylindrical contact caps: Type A. This standard covers dimensional systems but does not standardize characteristics.
