Principle

A constant amplitude, cyclic force is applied by a single actuator at a predetermined load line and
position on the rail head. The load, position and line of application to be used are determined from the
vertical stiffness of the fastening assembly, axle loads and curve conditions of the track for which the
fastening assembly is being tested.
Performance is determined by the change in clamping force, longitudinal rail restraint, vertical
stiffness and rail position, and visual inspection of the components during test.

the fastening assembly under test is designed. The rail shall be unlaminated and have neither loose
rust on the surface nor be polished on the foot by repeated testing.
The head of the rail may be modified to accommodate the load application head except when testing
fastenings which support the web of the rail. In this case, the dimension X, as shown in Figure 1,
refers to the design rail section for the fastening assembly.
!For embedded rail, the rail is part of the test specimen and its length is specified in 6.1."

6.1

Test specimens
Sleeper or other rail support

A sleeper, half sleeper, concrete block or other rail support with cast-in fastening components or
holes, and rail seats, as made without modification for this test. It is recommended that two sleepers
or half sleepers are used if the cast-in fastening components or holes are non-symmetrical about the

For surface mounted rail on slab track, the fastening system shall be mounted in the centre of the top

of a reinforced concrete block. The length of the block, normal to the rail, shall be ≥ 500 mm and the
width ≥ 300 mm. If, for stability, it is necessary to test two rail seats, the width of the block shall be
≥ 2 × the design fastening spacing in the track. The depth of the block shall be the depth of the slab or
(200 ± 10) mm, whichever is the smaller.
For surface mounted fastening systems on slab track, with continuous support of the rail, the test shall
be performed using a length of pad equal in length to the design spacing of the fastening along the
rail. The piece of rail used for the test shall be at least as long as the piece of pad and the size of the
concrete block shall be sufficient to provide support to the full length of the piece of pad.
!For embedded rail the channel containing the rail shall be contained in a concrete block similar to
that for surface mounted rail on sleepers, bearers and slab track.
For mechanically fastened embedded rail, the length of rail shall be the typical spacing of fastenings.
For adhesively fastened embedded rail, the length of the rail shall be 0,5 m to 0,85 m."

6.2

Fastening

7.1

Procedure for one rail
General

The following procedure is for the test when a rail is fixed to one end of the sleeper or half sleeper.
When two rails are used the procedure in Clause 8 shall be used.
The sequence of tests shall be 7.3, 7.4, 7.5, 7.6, 7.5, 7.4, 7.3 performed on test specimens
assembled in accordance with 7.2.1 or 7.2.2. At no time during the test sequence shall any part of the

fastening assembly be adjusted, retightened or modified.

7.2

Preparation for test

7.2.1

In line fastening

If the fastenings are in line fix a short length of rail to one rail seat using the fastening components as
assembled in track.
7.2.2

Offset fastening

If the fastenings are non-symmetrical, the test set up may become unstable during test. In such cases
fix a short length of rail to one rail seat on each of two adjacent sleepers or half sleepers as shown in
Figure 2. On slab track with non-symmetrical fastenings a section of slab with two rail seats should be
used.

Figure 2 — Arrangement of test sleepers for offset fastenings

7.3

Clamping force

Determine the clamping force of the assembly using the procedure in EN 13146-7:2012. If the test is
being carried out on two rail seats with indirect fastenings (e.g. as described in 7.2.2), the vertical
force is applied directly over the centre line of each of the rail seats in turn, whilst the anchors of the
baseplate at the other rail seat are partially unfastened. The clamping force is determined as the
mean of the measured values for the two rail seats.

7.4

Longitudinal rail restraint

Determine the longitudinal rail restraint or longitudinal stiffness, as appropriate, using the procedure in
!EN 13146-1:2012+A1:2014". If the test is on two adjacent rail seats as described in 7.2.2 the
result shall be expressed as:
Longitudinal rail restraint (F) = (measured value) / 2 kN
The tensile load applied to the rail before and after the repeated load test shall be in the same
direction.

7.5

Vertical static stiffness of fastening assembly

For one rail seat follow the procedure in EN 13146-9:2009, 7.1.4. If the specimen includes two
adjacent rail seats in accordance with 7.2.2 the applied load shall be 2 FSAmax and the rate of loading
(240 ± 20) kN/min. This is applied through a load frame so that it is distributed equally between the

EN 13146-4:2012+A1:2014 (E)

EN 13146-4:2012+A1:2014 (E)

two rail seats. The vertical stiffness is calculated from the equation in EN 13146-9:2009, 7.1.4 when
the applied force is increased from 1 kN to 1,6 FSAmax.

7.6

Cyclic loading

The values of α and X shall be as given in EN 13481-2:2012, EN 13481-3:2010, EN 13481-4:2012,
EN 13481-5:2012 and EN 13481-7:2012, as appropriate.
Set up the test arrangement as shown in Figure 3 or when appropriate Figure 4, with the base of the
test specimen supported on a rigid surface with a layer of plywood, gypsum board or other
conformable material between the specimen and support. Stops shall be fixed to the rigid support to
prevent longitudinal or transverse movement of the test specimens.
Use one of the load application arrangements shown in Figure 5 without any modification to the rail
foot. The load application strut shall have a width parallel to the longitudinal axis of the rail of
(100 ± 10) mm and a radius of curvature, normal to the rail head, greater than the radius of the
contact surface on the rail such that the strut maintains a line contact with the rail under all load
conditions. When testing embedded rail fastenings an unmodified rail section has to be used.
If two adjacent rail seats are under test in accordance with 7.2.2, the application point of the load shall
be chosen in order to balance the loading on the two rail seats.
Measure the assembly dynamic stiffness in accordance with EN 13146-9:2009, 7.2.4. Select the
maximum load (PV/cos α kN) from EN 13481-2:2012, EN 13481-3:2012, EN 13481-4:2012,

EN 13481-5:2012 and EN 13481-7:2012, as appropriate in accordance with rail size, axle load, radius
of curves and pad stiffness.
Slowly load the test assembly to the maximum load ± 1 kN, or (2 × maximum load ± 2) kN if two
adjacent rail seats are being tested, at a rate not exceeding 100 kN/min for a single rail seat and
200 kN/min for two rail seats. Remove and reapply the load 10 times at the same rate as the first
cycle. During the last three cycles the resultant force shall be acting to within the tolerances (α ± 0,5)°
and (X ± 1) mm at maximum load.
Apply an alternating load to the test specimen from a minimum load of (5 ± 1) kN, or (10 ± 1) kN for
6
two rail seats, to a maximum load, for 3 × 10 cycles at a frequency of (4 ± 1) Hz. Within the first 1 000
cycles measure the dynamic displacement of the rail relative to the sleeper or other support, at each
measuring point shown in Figure 6, for at least one loading cycle. Repeat the rail displacement
6
measurements after 3 × 10 cycles. Intermediate displacement measurements may be made for
information.
During this test, the maximum temperature of any component shall not exceed 50 °C. Cooling by fan
or a slight reduction in frequency within (4 ± 1) Hz, or a temporary stop in loading can be used to
avoid overheating.

If the fastenings are offset fix a short length of rail to each pair of rail seats on adjacent sleepers as
shown in Figure 2.
8.3.3

Clamping force

Perform the test as described in 7.3. The result shall be reported as the mean of individual results for
each rail seat or pair of rail seats.
8.3.4

Longitudinal rail restraint

Perform the test as described in 7.4. The result shall be reported as the mean of individual results for
each rail seat or pair of rail seats.
8.3.5

Vertical stiffness

Perform the test as described in 7.5. The result shall be expressed as the mean of individual results
for each rail seat or pair of rail seats.
8.3.6

Cyclic loading

The value of α and X shall be as given in EN 13481-2:2012, EN 13481-3:2012, EN 13481-4:2012,
EN 13481-5:2012 and EN 13481-7:2012, as appropriate.
Set up the test arrangement as shown in Figure 7 and follow the procedure in 7.6. The test assembly
shall be subject to a maximum load of 2PV if a single sleeper is used and 4PV if a pair of sleepers is
used. The maximum rate of loading shall be 200 kN/min for a single sleeper and 400 kN/min for a pair
of sleepers.
8.3.7

Repeat tests

Vertical stiffness (see 8.3.5), longitudinal rail restraint (see 8.3.4) and clamping force (see 8.3.3) tests
are repeated in that sequence.

8.3.8

Final inspection

Perform the final inspection as described in 7.8.
