This document establishes the means to achieve an electronic representation of rolling bearing data by providing a reference dictionary needed to describe various data about rolling bearings together with their descriptive properties and domains of values in various International Standards relevant to rolling bearings. This document is intended to facilitate the use, manipulation and exchange of rolling bearing data, for example, manufacturing, distribution and usage. This document specifies a reference dictionary that contains: —？a definition of a general class of bearings intended to be further extended by reference dictionaries specifying bearings in other International Standards; —？definitions and identifications of the classes of rolling bearings as they are described in the various International Standards relevant to rolling bearings, with associated classification scheme; —？definitions and identifications of data element types that represent properties of rolling bearings; —？definitions and identifications of domains of values that prove useful for describing the above-mentioned data element types. Each class, property or domain of values of this application domain constitutes an entry of the reference dictionary defined in this document. It is associated with a computer-sensible and a human-readable definition, and with a computer-sensible identification. Identification of a dictionary entry allows for unambiguous reference from any application. Definitions and identifications of dictionary entries are defined by means of standard data, which consist of instances of the EXPRESS entity data types defined in the common dictionary schema and in their extensions defined in ISO？13584-25. Identification dictionary is given in Annex？A. The following are within the scope of this document: —？standard data that represent the classes of rolling bearings; —？standard data that represent the properties of rolling bearings; —？standard data that represent domains of values used for properties of rolling bearings. The following are outside of the scope of this document: —？methodology for structuring parts families used for specifying standard data defined in this document; —？an implementation method by which the standard data defined in this document can be exchanged. NOTE？1？The structure of the physical file used for exchanging the standard data defined in this document is specified in ISO？10303？21. NOTE？2？The physical file used for exchanging the standard data is compliant with ISO？13584-42:2010. NOTE？3？It is intended to provide an OntoML-based (XML) representation of the standard data when ISO？13584-32 (OntoML) is published. This document does not establish the reference dictionaries for linear motion rolling bearings and spherical plain bearings.
