Introduction

This Introduction provides an explanation of the concepts and reasoning used in the drafting of this

document. Its inclusion also ensures that during future revisions, restrictions are removed where technology

progresses and held where it does not, thus ensuring continued safety as new manufacturers, products and

technologies are introduced.

The most commonly used standards of the world for the supply of railway rails have been reviewed during

the preparation of this document. However, modern rail production technology within the European Union

has demanded a completely new look at the philosophy and content of this part of EN 13674.

Whenever possible this part of EN 13674 is performance based, recognizes the European Quality System

standard EN ISO 9001 and requires manufacturers to offer the latest proven technology to consistently

satisfy the demanding quality of the required product.
Rail grading is based on hardness rather than tensile strength.

The acceptance tests have been designed to control those characteristics of the rail steel and rail that are of

relevance to the production of high quality rails and the demands of the railway.

The steel grades covered by this part of EN 13674 reflect trends in railway usage and heat-treated rails are

included. This document includes rail profiles for switch and crossing rails used in conjunction with Vignole

rails having a linear mass 46 kg/m and above.

To ensure the supply of high quality rails, some restrictions on production processes have been imposed.

This document supersedes other standards covered by the scope. In addition CEN required, where possible,

a performance based standard, taking into account safety implications and at the same time addressing

modern production technology. It was recognized that there would be few opportunities (and these would

have to be for transparent safety considerations) for derogation from this document to operate between the

user and the manufacturer.

This document reflects this change in philosophy from the traditional content of rail standards. A review was

undertaken of the most commonly used rail standards of the world. All relevant aspects important to both

user and manufacturer were considered with the aim of ensuring that all of the content had specific

usefulness and relevance. For example rail grading and much of this European Standard has been based on

hardness rather than tensile strength. While the two are directly related, hardness is very quick and cheap to

carry out and provides more relevant guidance to the user particularly where properties vary in different

parts of the profile.

Since many rail manufacturers would not have previously carried out proving trials, the document includes a

prerequisite for all manufacturers to prove conformity against a set of qualifying test criteria at the time of

tendering. The qualifying tests include all “normal” acceptance test results plus new ‘type-casting’ features

such as fracture toughness, fatigue and residual stress (see EN 13674-1). To provide users with the

necessary confidence, acceptance limits have been based on results from rail known to have performed well

in demanding track installations.

One aspect of this document, which is a complete break from tradition, is the inclusion of quality assurance

and inspection clause as part of product integrity.

So that quality management systems are consistent across all manufacturers and that users have the best

assurance for the consistency of required product quality on this safety critical component of the track, the

rail standard requires that the manufacturers’ quality assurance systems are at least equivalent to the

requirements of a quality management standard such as EN ISO 9001. The inclusion of this requirement also

reduces the need to incorporate detailed method and calibration descriptions on items such as normal

chemical composition determination and the need to define more extensive testing.

Ideally, manufacturing techniques should not be referenced in a product standard. However, some rail

attributes are either not known in an exact manner or are not measurable with satisfactory statistical

significance. In such cases best practice manufacturing techniques have been included as a last resort. The

---------------------- Page: 8 ----------------------
SIST EN 13674-2:2019
EN 13674-2:2019 (E)

equipment specified is that which gives the best probability of achieving the required product for use in

track. In the future new technology can add to, but preferably will reduce or delete such items.

Examples of areas where the technological state of the art renders the standard less than complete include:

— oxide/oxygen relationships;
— hydrogen test techniques;
— roller straightening effects on residual stresses;
— roller straightening effects on contact scrub;
— measurement and effect of residual stresses throughout the rail.

1 Scope

This document specifies switch and crossing rails that carry railway wheels. These are used in conjunction

with Vignole railway rails.

This document is not applicable for the check rails that do not carry railway wheels.
