This document applies to rubber and rubber to metal parts designed to be fitted on railway vehicles and similar vehicles running on dedicated tracks with permanent guide systems, whatever the type of rail and the running surface.

Typical applications of the rubber and rubber to metal parts include:

- vehicle suspension systems;

- equipment mounting systems;

- joints (e.g. end-mountings of dampers, rubber-based bearings, rubber-based parts used on mechanical couplings);

- limit stops.

These parts can be:

- made entirely of rubber, operating on their own or in combination with other elastic parts;

- made of rubber and metal, adherent together or not.

This document specifies;

- characteristics that rubber and rubber to metal parts shall achieve, together with applicable inspection and test methods to be carried out for verification.

This document does not apply to:

- rubber diaphragms for pneumatic suspension

springs;  elastic parts of buffing and drawgear springs;

- diaphragms, bellows and seals;

- hoses and tubings;

- transmission belts.

This document is valid for rail vehicles equipped with buffers and screw coupling systems.

In order to allow operation and coupling of trainsets or vehicles, this document specifies the defined free space for the shunter called the "Berne rectangle" and the necessary free space for the installation of the rescue coupler.

This document specifies the location, fixing, and free spaces on the headstock of:

— buffers;

— screw coupling systems;

— end cocks;

— pneumatic half couplings;

— connections for electric cables.

It also specifies the calculation of the width of the buffer heads.

Unless otherwise displayed, all dimensions given in this document are nominal values.

This document is limited to specifying the requirements when applying lubricant to the interface between the wheel flange and the rail (active interface), either directly or indirectly to the wheel flange or to the rail and includes both trainborne and trackside solutions.

This document only covers the equipment and application of lubricant to the active interface.

This document defines:

— the characteristics that systems of lubrication of the wheel-rail interface shall achieve, together with applicable inspection and test methods to be carried out for verification;

— all relevant terminology which is specific to the lubrication of the wheel-rail interface.

This document only applies to the mainline railway.

NOTE This document can also be used for other railways, e.g urban rail.
