5 Requirements for fastening systems for embedded track
5.1 Test specimens

For category A+ and category A fastenings, tests shall be carried out on a specimen with an embedded

rail with a supported length of (0,8 ± 0,01) m.
---------------------- Page: 10 ----------------------
SIST EN 17319:2020
EN 17319:2020 (E)

For category B fastenings, tests shall be carried out on a specimen with an embedded rail with a

supported length of (0,6 ± 0,01) m.
5.2 Longitudinal rail restraint or longitudinal stiffness

The determination of longitudinal rail restraint or the longitudinal stiffness is necessary for the

assessment of the transfer of longitudinal forces in the rail to the supporting structure. The

measurements of the restraint or stiffness are part of the repeated loading test as described in 5.4.

For a mechanical fastening system for embedded rails, the requirement for the mean longitudinal rail

restraint of the system shall be a minimum of 7 kN, determined using the method set out in EN 13146-1.

For an adhesive fastening system for embedded rails, the longitudinal stiffness k shall be measured in

accordance with EN 13146-1, between 0 mm and D mm relative displacement per equivalent length of

support without visible damage. The requirement for D shall be agreed between the supplier and the

purchaser and the minimum longitudinal force shall be 7kN. If no other value is agreed, then D shall be

7 mm.

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

max

EN 13146-1 may be used in the calculation. In such cases and subject to agreement between the

purchaser and supplier, the minimum requirement for longitudinal rail restraint F, or the longitudinal

force F at D , may be reduced.

If the rail fastening system is claimed to be designed to provide a waterproof seal between the rail and

the road surface or channel, there shall be no visible damage on the top surface during or after the test.

5.3 Vertical assembly stiffness

The determination of vertical assembly stiffness is necessary for the assessment of the transfer of

vertical forces in the rail to the supporting structure. The measurements of the vertical assembly

stiffness are required within the repeated load test procedures in 5.4.

Fixtures shall be used to ensure that the applied load acts through the centre line of the rail web.

Values of test loads for measurement of stiffness are given in Table 2.
Table 2 — Loads for measurement of stiffness
Fastening category F and F F and F
SA1 LFA1 SAmax LFAmax
kN kN
A and A+ 1 32
B 1 43
NOTE These test loads apply to a specimen with the rail
embedded for 0,8 m in Category A+ and A, and 0,6 m in Category B.
In case of a shorter specimen, the test load and the load speed shall
be reduced proportionally.

Measured stiffnesses kSA and kLFA shall be reported as stiffness per unit length l [MN/m/m].

When required by the purchaser, any further vertical stiffness measurements shall be made using the

appropriate procedure in EN 13146-9.
5.4 Effect of repeated loading

The effect of repeated loading for embedded rails shall be determined by the procedure in EN 13146-4,

except that the clamping force shall not be measured.
---------------------- Page: 11 ----------------------
SIST EN 17319:2020

Values for test loads and angles shall be as shown in Table 3. The value of k is the value determined in

B 33 35 33 38 33 48

NOTE 1 These test loads apply to a specimen with the rail embedded for 0,8 m in Category A+ and A,

and 0,6 m in Category B. In case of a shorter specimen, the test load and the load speed shall be reduced

proportionally.

NOTE 2 Further information about the determination of loads and angles is given in CEN/TR 17320.

As required by EN 13146-4, the following measurements shall be performed before and after repeated

loading. The change in performance shall not exceed the values shown below.
— Longitudinal rail restraint or longitudinal stiffness change ≤ 20 %;
— Vertical static assembly stiffness change ≤ 25 %.

The requirement for change in vertical static assembly stiffness is not applicable to fastening systems

with stiffness, k ≥ 300 MN/m/m.

If the rail fastening system is claimed to be designed to provide a waterproof seal between the rail and

the road surface or channel, there shall be no visible damage on the top surface during or after the test.

Compliance with Category A+ implies compliance with Categories A and A+.
5.5 Electrical insulation

Requirements for electrical insulation in the fastening system are specific to the signalling and power

supply configurations for each project. Guidance is given in Annex A.
5.6 Uplift restraint

Measurement of the uplift restraint of the fastening system is required after the repeated load test is

carried out as set out in 5.4. The test method is described in Annex B. The required value for the proof

load, F is 10 kN per metre of supported length of embedded rail.

The fastening system shall be considered to have passed the test if all of the following criteria are met:

— The rail is not pulled out of the specimen.

— There are no cracks visible, neither at proof load, nor in unloaded condition after the proof load, in

any element of the rail fastening system. If the rail fastening system is claimed to be designed to

provide a waterproof seal between the rail and the road surface or channel, there shall be no visible

fracture or deformation of that element which indicates a failure of the waterproof sealing function.

This applies both at proof load and in unloaded condition after the proof load.

— There are no structural cracks visible in the specimen surrounding the rail fastening system.

SIST EN 17319:2020
EN 17319:2020 (E)

NOTE Localized spalling at the surface of the specimen immediately adjacent to the rail fastening system is

not identified as a structural crack.
5.7 Uplift stiffness

On structures such as long bridges, the uplift forces transmitted between the track and the structure at

locations such as the bridge deck ends may be calculated by the method given in EN 1991-2. This

method requires as an input the value for uplift stiffness of the fastening system. Measurement of this

uplift stiffness, k , shall be made as set out in Annex C.
5.8 Attenuation of noise and vibration
Guidance is given in Annex D.
6 Requirements for fastening systems for ballasted track and for ballastless
track with rails on the surface
6.1 Test specimens
Tests shall be carried out on a specimen containing one fastening assembly.
6.2 Clamping force

The determination of clamping force is necessary for the assessment of the strength of the fixation of

the rail to its support. The clamping force shall be measured using the method set out in EN 13146-7.

The measurement of the clamping force is part of the repeated loading test as described in 6.5. This test

is not applicable to web supported fastening systems.
6.3 Longitudinal rail restraint

The determination of longitudinal rail restraint is necessary for the assessment of the transfer of

longitudinal forces in the rail to the supporting structure. The measurement of the restraint is part of
