To ensure safety and interoperability, this document gives: - the limits for in-service and off-vehicle wheelsets; - the operations to be carried out for which the specific values (and/or criteria) remain to be defined in the maintenance plan. This document applies to wheelsets and axle boxes complying with the following European standards: - EN 13103-1:2017; - EN 13260:2020, EN 13261:2020, EN 13262:2020; - EN 13979-1:2020; - EN 13715:2020; - EN 13749:2021; that comprise: - the axle fitted with wheels of diameters greater than or equal to 330 mm; - axle boxes with bearings and grease. This document is also applicable to wheelsets: - fitted with brake discs, final drive, transmission or noise-damping systems, as appropriate; - not complying with the above European standards, but complying with the international requirements in force, for example in UIC leaflets, before the approval of these standards; - with tyred wheels; - with resilient wheels. For equipment not covered by Directive 2016/797/EC, this European Standard may be applied, noting that different values may be used. All dimensions in this document are in millimetres (mm). It is necessary to describe in a specific document the tasks to be performed in order to maintain wheelsets within the limits defined therein. NOTE The specific values and criteria are defined in an appropriate maintenance plan.

The aim of this document is to define a design assessment procedure of a forged and rolled monobloc wheel (RST). This assessment is carried out before the wheel is commissioned. This document describes, in particular, the assessment to be performed in order to use wheels on a European network which, in addition, have quality requirements in conformity with those defined in EN 13262. This assessment requires that the conditions of use for the wheel are defined and this standard provides a method for defining those conditions. The assessment of the design covers four aspects: - a geometrical aspect: to allow interchangeability of different solutions for the same application; - a thermomechanical aspect: to manage wheel deformations and to ensure that braking will not cause wheels to fracture; - a mechanical aspect: to ensure that no fatigue cracks occur in the wheel web and that no permanent deformation occurs under exceptional loading; - an acoustic aspect: to ensure that the solution chosen is as good as the reference wheel. This document does not cover assessment of the hub or of the rim. This document has been drawn up for wheels of non-powered tread-braked wheelsets and applies in full to this type of wheel. For wheels on which disc brakes are mounted or toothed transmission wheels or even wheels with noise reduction devices, the requirements may be amended or supplemented. For urban railway vehicles, other standards or documents may be used.

This document lays down requirements for the preparation, administration and reproduction of technical drawings for railway applications. It complies with the requirements of EN, ISO or IEC Standards for technical drawings. It applies to technical drawings for railways, irrespective of technology i.e. mechanical, pneumatic, hydraulic, electronic etc. The document applies throughout the total life span of the drawings. It applies to all the railway organizations and parties concerned with technical drawings, and to suppliers preparing drawings for railway applications. This document does not apply to the technical contents of the document. Neither does the standard apply to building documentation.

This document applies throughout the total life span of the documents. This document 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 document 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.
