This document specifies requirements for pads for disc brakes of railway rolling stock.

This document is applicable to pads designed to be fitted to disc braked rail vehicles. The brake pad may be manufactured from any material.

The document defines requirements and generic test programs for brake pads. In order to qualify the brake pad performance in accordance with the classification the standard provides fixed parameter figures as categories defined in paragraph classification scheme.

This series of standards applies to welding of metallic materials in the manufacture and maintenance of railway vehicles and their components.

This part of the series defines the classification levels as well as the requirements for manufacturers of welded railway vehicles and components.

This document specifies the terms and definitions used in the ISO 22074- series of standards related to rail fastening systems. The present document includes definitions of various categories of fastenings suitable for application to different track and traffic conditions.

This European Standard specifies the principles and methods for a rig performance test of the system of axlebox rolling bearing(s), housing, seal(s) and grease. Test parameters and minimum performance requirements for vehicles in operation on main lines are specified. Different test parameters and performance requirements may be selected for vehicles in operation on other networks (e.g. urban rail). This standard is historically developed for outboard applications but can be used for vehicles with other bearing arrangements (e.g.: inboard application or single wheels).

It gives some possible examples where a "sequenced performance test" addresses the broad range of different service conditions within a specific application or vehicle platform into account.

It describes in detail the water tightness test and basic principles and minimum requirements for a field test.

This European Standard only applies to axleboxes equipped with rolling bearings and greases according to EN 12080 and EN 12081.

This European Standard characterises the quality of track geometry based on parameters defined in EN 13848-1 and specifies the different track geometry classes which should be considered.

This European Standard covers the following topics:

— description of track geometry quality;

— classification of track quality according to track geometry parameters;

— considerations on how this classification can be used;

— this European Standard applies to high-speed and conventional lines of 1 435 mm and wider gauge;

— this European Standard forms an integral part of EN 13848 series.
