European foreword
This document (EN 13481-2:2022) has been prepared by Technical Committee CEN/TC 256 “Railway
applications”, the secretariat of which is held by DIN.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by January 2023, and conflicting national standards shall
be withdrawn at the latest by January 2023.
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 supersedes EN 13481-2:2012+A1:2017.
The main changes compared to the previous edition are as follows:
a) inclusion of tests for fastenings with very low stiffness;
b) changes to the loading conditions for Category B fastenings;
c) inclusion of details of in-service testing, replacing the reference to EN 13146-8, which is to be
withdrawn;
d) editorial changes to make clear which requirements are based on laboratory testing.
This European Standard is one of the series EN 13481 “Railway applications — Track — Performance
requirements for fastening systems”, which consists of the following parts:
— Part 1: Definitions
— Part 2: Fastening systems for concrete sleepers in ballast
— Part 3: Fastening systems for wood and polymeric composite sleepers
— Part 4: Fastening systems for steel sleepers
— Part 5: Fastening systems for ballastless tracks
— Part 7: Fastening systems for switches and crossings, check rails, insulated rail joints and rail expansion
devices
NOTE Part 6 does not exist in this series.
These European Standards are supported by the test methods in the series EN 13146 “Railway
applications — Track — Test methods for fastening systems”.
This document has been prepared under a Standardization Request given to CEN by the European
Commission and the European Free Trade Association, and supports essential requirements of EU
Directive(s) / Regulation(s).
For relationship with EU Directive(s) / Regulation(s), see informative Annex ZA, which is an integral part
of this document.
Any feedback and questions on this document should be directed to the users’ national standards body.
A complete listing of these bodies can be found on the CEN website.
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia,
Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland,

Introduction
A series of tests is used to assess the suitability of fastening systems for use in railway track, i.e. for type
approval of complete fastening systems. This document only sets requirements considered relevant to
ensure the safe, long-term operation of the track system. The test methods are described in other
associated standards.
The various Categories of rail fastenings used in this document are defined in EN 13481-1:2012.
1 Scope
This document is applicable to fastening systems in Categories A – E as specified in EN 13481-1:2012, 3.1
for use on concrete sleepers in ballasted track with maximum axle loads and minimum curve radii as
shown in Table 1.
Table 1 — Fastening category criteria
Category Maximum design axle load Minimum curve radius
kN m
A 130 40
B 180 80
C 260 150
D 260 400
E 350 150
NOTE The maximum axle load for Categories A and B does not apply to maintenance vehicles.
The requirements apply to:
— fastening systems which act on the foot and/or web of the rail including direct fastening systems and
indirect fastening systems;
— fastening systems for rail sections included in EN 13674-1 (excluding 49E4) or EN 13674-4.
This document is not applicable to fastening systems for other rail sections, rigid fastening systems or
special fastening systems used at bolted joints or glued joints.
This document is for the type approval of complete fastening systems.
