European foreword
This document (EN 13146-9:2020) 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 October 2020, and conflicting national standards shall
be withdrawn at the latest by October 2020.
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 13146-9:2009+A1:2011.
In this revision of EN 13146-9:2009+A1:2011 the procedures for setting up and calibrating instruments
have been brought into line with the requirements in EN 13146-4 and the procedure for high-frequency
stiffness testing has been moved into an informative annex.
This document is one of the series EN 13146 Railway applications — Track — Test methods for
fastenings systems, which consists of the following parts:
— Part 1: Determination of longitudinal rail restraint;
— Part 2: Determination of torsional resistance;
— Part 3: Determination of attenuation of impact loads;
— Part 4: Effect of repeated loading;
— Part 5: Determination of electrical resistance;
— Part 6: Effect of severe environmental conditions;
— Part 7: Determination of clamping force and uplift stiffness;
— Part 8: In-service testing;
— Part 9: Determination of stiffness;
— Part 10: Proof load test for pull-out resistance.
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, 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
This part of the EN 13146 series brings together test methods for measuring the stiffness of pads and
fastening assemblies under static and low-frequency dynamic loading.
Earlier versions of this document included test methods applicable to higher frequencies. These
methods are still included in an informative annex.
No method for testing at acoustic frequencies is included. The procedure in EN 15461, which involves
testing a length of track incorporating the fastening assemblies under test, is recommended.
