This document gives guidelines for the cross wind assessment of railways. This document is applicable to all passenger vehicles, locomotives and power cars (with a maximum train speed above 140 km/h up to 360 km/h) and freight wagons (with a maximum train speed above 80 km/h up to 160 km/h) and track gauges from 1 435 mm to 1 668 mm inclusive. For passenger vehicles, locomotives and power cars with a maximum train speed between 250 km/h and 360 km/h, a requirement to demonstrate the cross wind stability is imposed. This document is not applicable to light rail and urban rail vehicles.

This document applies to passenger body side entrance systems of all newly designed railway vehicles such as tram, metro, suburban, mainline and high-speed trains that carry passengers. The requirements of this document also apply to existing vehicles undergoing refurbishment of the door equipment, as far as it is reasonably practicable. This document also specifies the requirements for testing of entrance systems. This document makes reference to manual and power operated entrance systems. For manual doors, clauses referring to power operation are not applicable. This document does not apply to the following: - entrance systems for equipment access, inspection or maintenance purposes and for crew only use; - doors on freight wagons; and - doors or hatches specifically provided for escape under emergency conditions.

This part of the ISO 22480 series defines technical criteria and control procedures which need to be satisfied by the constituent materials and the finished concrete sleepers and bearers, i.e.: precast concrete sleepers, twin-block reinforced sleepers, bearers for switches and crossings, and special elements for railway tracks.

The main requirement of concrete sleepers and bearers is the transmission of vertical, lateral and longitudinal loads from the rails to the ballast or other support. In use, they are also exposed to frost damage and to moisture, which can result in detrimental chemical reactions within the sleeper.

In this standard mechanical tests are defined which provide assurance of the capability of sleepers or bearers to resist repetitive loading and provide sufficient durability. In addition, controls are placed on manufacturing processes and tests to ensure that the concrete will not suffer degradation in service through chemical reaction and frost damage.

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.

This document specifies a laboratory test procedure for determining the electrical resistance, in wet conditions, between the running rails provided by a fastening system fitted to a steel or concrete sleeper, bearer or element of ballastless track.

It is also applicable to embedded rail.

This test procedure applies to a complete fastening assembly. It is relevant to signalling currents, not to traction currents.

A reference procedure and an alternative procedure are included.

This International Standard specifies the laboratory test procedure for determining the clamping force exerted by the fastening system on the foot of the rail by measuring the force to separate the rail foot from its immediate support. When required, the procedure is also used to determine the uplift stiffness of the fastening system. It is applicable to systems with and without baseplates on all types of sleepers, bearers or elements of ballastless track. The test does not determine the security of the fastening components fixed into the sleeper or other fastening system support.

This test procedure applies to a complete fastening assembly. It is not applicable to fastening systems for embedded rail or other fastening systems which do not act on the foot of the rail.
