scope:

This European Standard applies throughout the total life span of the documents. This standard applies to all the railway organisations and partners concerned with technical documents and to suppliers preparing documents on behalf of railway companies or railway network users. This European Standard describes the basis of revising technical design documents for railway applications, without considering additional company requirements. These basic requirements apply to all technical design documents independent of the material form: e.g. transparency originals, plotter drawings, aperture cards, computer readable data media, photoprints, COM-fiches etc., also for a computerised set of information.
