NOTE The maximum axle load for categories A and B does not apply to maintenance vehicles
The requirements apply to the following:
a) fastening systems which act on the foot and/or web of the rail including direct fastening systems and systems which incorporate a baseplate;
b) fastening systems which incorporate concrete elements which each have not more than one supporting element per rail;
c) adhesive and mechanical fastening systems for embedded rail excluding rail cast into road pavements.
In the case of (b) the concrete element is considered to be part of the fastening system. If the system includes concrete elements which each have more than one supporting location per rail, those concrete elements are considered to be part of the slab and not part of the fastening system.
This standard is only applicable to fastening systems for rail sections in EN 13674-1 and EN 13674-4; it is not applicable to special fastening systems for use at bolted joints.

SIST EN 13481-5:2012
EN 13481-5:2012 (E) 5 Introduction Various tests are necessary to assess the performance of fastening systems of railway tracks. In this European Standard, a requirement for longitudinal rail restraint is included to control rail creep and pull apart in the event of a broken rail. The relationship between longitudinal rail restraint and the overall design of the track slab requires consideration. No satisfactory test is available to determine the attenuation of impact loads on slab track. The relative performance may be assessed by the procedure in EN 13146-3:2012 with the fastening system on a concrete sleeper. The laboratory test for the effect of repeated loading is the means of assessing potential long term performance of the fastening in track. For systems in which the rail is continuously supported, test procedures are modified to take account of the change from discrete support. SIST EN 13481-5:2012

The requirements apply to: a) fastening systems which act on the foot and/or web of the rail including direct and indirect systems; b) fastening systems which incorporate concrete elements and which each have not more than one supporting element per rail, including booted concrete blocks and sleepers complete with boots; c) adhesive and mechanical fastening systems for embedded rail but excluding rail cast into road pavements. In the case of (b), the concrete element is considered to be part of the fastening system. If the system includes concrete elements which each have more than one supporting location per rail, those concrete elements are considered to be part of the slab and not part of the fastening system. This standard is only applicable to fastening systems for rail sections in EN 13674-1 (except 49E4) and EN 13674-4+A1; it is not applicable to special fastening systems for use at bolted joints or glued joints.

5 Requirements
5.1 Longitudinal rail restraint
For discrete fastening systems the longitudinal rail restraint shall be not less than 7 kN when
measured by the procedure in prEN 13146-1:2009. For use in category D tracks (> 250 km/h) the
longitudinal rail restraint shall be not less than 9 kN.
For embedded rail with an adhesive fastening system the longitudinal stiffness K shall be measured
L
in accordance with prEN 13146-1:2009 between (0 – 7) mm relative displacement without visible
damage.
On structures such as long bridges, the longitudinal force transmitted between the track and the
structure may be calculated by the method in EN 1991-2. The value of F measured in accordance

with prEN 13146-1:2009 may be used in the calculation. In such cases and subject to agreement
between the purchaser and manufacturer, the minimum requirement for longitudinal restraint may be
reduced.
5.2 Assembly and pad stiffness
As required by prEN 13146-4:2009 the assembly static stiffness and assembly low frequency dynamic
stiffness shall be measured in accordance with EN 13146-9. Measurement of the rail pad static
stiffness is required at the purchaser’s discretion in accordance with prEN 13146-8:2009. If the
purchaser requires any of the following it shall be measured in accordance with EN 13146-9:
pad low frequency dynamic stiffness;
assembly high frequency dynamic stiffness.
Test loads are given in Table 2.
NOTE Guidance on the measurement of pad high frequency stiffness is given in EN 13146-9:2009, Annex A.
For the measurement of assembly properties at acoustic frequency see EN 15461.

NOTE For embedded rail the stiffness shall be expressed per unit length.
5.3 Effect of repeated loading
This shall be determined by the procedure in prEN 13146-4:2009. In the case of twin block, booted
concrete sleepers the whole sleeper shall be subject to test using the procedure for two rail seats.
The test loads and positions shall be as shown in Table 3.
The following measurements shall be performed before and after repeated loading. The change in
performance shall not exceed the values shown below. For fastening systems which support the web of
the rail and adhesive fastening systems for embedded rail, the change in clamping force does not apply.
Longitudinal rail restraint change ≤ 20 %; or
Longitudinal stiffness change ≤ 20 %;
Vertical static stiffness change ≤ 25 %;
Clamping force change ≤ 20 %.
Compliance with Category C implies compliance with Categories C and D
Compliance with Category B implies compliance with Categories A and B
