This Technical Specification (CEN/TS) was approved by CEN on 27 December 2020 for provisional application.

The period of validity of this CEN/TS is limited initially to three years. After two years the members of CEN will be requested to
submit their comments, particularly on the question whether the CEN/TS can be converted into a European Standard.

CEN members are required to announce the existence of this CEN/TS in the same way as for an EN and to make the CEN/TS
available promptly at national level in an appropriate form. It is permissible to keep conflicting national standards in force (in
parallel to the CEN/TS) until the final decision about the possible conversion of the CEN/TS into an EN is reached.

CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia,
Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway,

European foreword
This document (CEN/TS 15427-2-3:2021) has been prepared by Technical Committee
CEN/TC 256 “Railway Applications”, the secretariat of which is held by DIN.
Attention is drawn to the possibility that some of the elements of this document may be the
subject of patent rights. CEN shall not be held responsible for identifying any or all such patent
rights.
This document is part of the series EN 15427, Railway applications - Wheel/Rail friction
management, which consists of the following parts:
— Part 1-1: Equipment and Application - Flange Lubrication
— Part 1-2: Equipment and Application - Top of Rail materials
— Part 1-3: Equipment and Application - Adhesion materials
— Part 2-1: Properties and Characteristics - Flange lubricants
— Part 2-2: Properties and Characteristics - Top of Rail materials
— Part 2-3: Properties and Characteristics - Adhesion materials
— Part 3: Rationale for requirements and further background information
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this Technical Specification: Austria, Belgium,
Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece,
Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway,
Poland, Portugal, Republic of North Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain,
Sweden, Switzerland, Turkey and the United Kingdom.
Introduction
Friction management using solid or fluid (oil, grease, etc.) substances at the wheel-rail interface
is a complex subject and includes the following aspects:
— lubrication of the wheel flange/ rail gauge corner interface, commonly referred to as “flange
or rail lubrication”;
— lubrication of the back of flange/ check rail interface; commonly referred to as “check rail
lubrication”;
— altering the level of friction at the interface between the top of rail and the wheel tread,
commonly referred to as “top of rail friction management”;
— altering the level of adhesion at the interface between the top of rail and the wheel tread.
This document sets out requirements for the material to be used for adhesion management. It
specifies requirements for the material, how to test it and how to approve it.
The main purpose of an adhesion material is to condition the wheel/ rail contact to either prevent
the occurrence of slipping or sliding or to enable recovery of traction/ braking where slipping or
sliding occurs.
The adhesion material should be tested to confirm there is:
— compatibility with top of rail systems;
— no intolerable increased risk of fire;
— no harmful environmental effects;
— no incompatibility between the different materials in use, particularly between solid and
fluid systems;
— satisfactory and consistent product quality and performance;
— no degradation to the safety of the railway (braking, signalling).
1 Scope
This document specifies the requirements of adhesion materials intended to be applied to the
interface between the wheel tread and the rail crown (active interface). It can be applied either
directly or indirectly to the wheel tread or rail.
It outlines the information required for most approval procedures, the method of testing and
routine control/monitoring of the material.
This document does not deal with Top of Rail materials. For Top of Rail materials see
CEN/TS 15427-2-2:2021.
