scope:

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.
