Scope

This section provides a solid basis for clearly defining the typical characteristics (types of data elements) of all components of electrical technology from basic components to assemblies and complete systems. Originally intended to provide the basis for information exchange on electronic/electrical components, the principles and methods of this part can be used in a wider range of fields, such as: components, assemblies and electrical technical coefficients and sub-factors. In addition, this standard provides for the establishment of classification hierarchies and the assignment of appropriate and relevant properties to each class so established in order to adequately describe the properties of objects belonging to that class. Use of this standard facilitates the description of data exchange for electrical technical coefficients by defining a structure for information exchanged in a computer-readable form. Each property exchanged has an unambiguously defined meaning and consistent naming, as well as an associated list of defined values, defined format, and defined units of measurement for all quantitative values. It also specifies: - control of changes to property definitions by version and revision number; - includes notes and comments that clarify and help define the application; - indicate the source of definitions and lists of values; - associated figures and formulas.
