Introduction
This European Standard completes the series EN 13230 Railway applications – Track – Concrete sleepers
and bearers, when the sleepers or bearers are manufactured with Under Sleeper Pad (USP). The USP is an
USP fixed to the bottom surface of the sleepers or bearers. This standard applies to the system constituted of
the concrete sleepers or bearers and the Under Sleeper Pad.
The following terms are used within to define the parties involved in using the EN as the technical basis for a
transaction:
— Purchaser: the operator or user of the equipment, or the customer of the material on the user’s behalf.
— Supplier: the body responsible for the use of the EN in response to the purchaser’s requirement. The
supplier is also responsible for requirements which apply to the producer or manufacturer. (Generally the
Supplier is the manufacturer of the concrete sleepers and has a Sub-contractor for the USPs.)

1 Scope
This European Standard is applicable to concrete sleepers or bearers with Under Sleeper Pads (USP)
physically bonded to concrete used in ballast track and defines the test procedures and their acceptance
criteria.
This standard provides particular information in the following areas:
— tests methods, tests arrangements and acceptance criteria of Under Sleeper Pads,
— tests methods, tests arrangements and acceptance criteria of concrete sleepers and bearers with Under
Sleeper Pads,
— data supplied by the purchaser and by the supplier,
— definition of general process of qualification,
— definition of routine tests.
This standard defines the specific test procedures for Under Sleeper Pad with or without concrete sleepers
and bearers:
— Fatigue tests,
— Tests of capability for stacked stocking of concrete sleepers or bearers fitted with USP,
— Pull-out test,
— Severe environmental condition test
In addition to specifying the basic testing of relevant properties of USP, this standard also sets out procedures
for testing fitness for purpose and provides information on quality monitoring as part of quality assurance
procedures. This standard does not, however, contain requirements pertaining to the properties of Under
Sleeper Pads. It is the responsibility of the purchaser to define these requirements.

5 Requirements for qualification and routine tests
5.1 General
This clause defines the objectives of tests or of demanded information about the system (sleeper with USP),
USP and concrete sleepers and bearers.
The general process and data sheets (USP and sleepers with USP) are described in Annex F and G.
If a tested USP is used with different concrete sleepers or bearers (different types or different manufacturing
process), the purchaser shall define which tests shall be done.
5.2 Summary of qualification tests and routine tests
The qualification tests and the routine tests consist of the following three stages:
— Tests for USP alone and for concrete block with USP (see Table 3);
— Tests for concrete sleepers and bearers without USP (see Table 4);
— Tests for concrete sleepers and bearers with USP (see Table 5).

5.3.1 Dimensions and masses of USP
The dimensions and masses of USP shall permit to respect the requirements of 5.4.
Test arrangement:
Dimensions and masses are measured with instruments adapted to controlled dimension (instruments
validated by the purchaser).
Qualification:
The purchaser shall approve the drawing and technical documentations given by supplier.
All the samples for qualification shall be checked according to the drawing and technical documentations.
5.3.2 Tensile strength of USP
The tensile strengths of USP are determined without the influence of manufacture of the sleepers.
The tensile strengths measured during the qualification tests shall determine the reference value of these
tensile strengths to confirm the quality of the USP during the routine tests. The test should permit the
measurement of the tensile strengths both parallel and perpendicular to the production direction of USP (if
there is a difference in production direction).

oSIST prEN 16730:2014
prEN 16730:2014 (E)
Test arrangement:
The test is performed on USP in accordance with EN ISO 527 series or ISO 37 and with the supplier’s
indications which are approved by the purchaser. The test shall be done on the USP without bonding and
protection layer. The supplier shall specify the thickness of the samples.
Qualification:
The test method shall be applied on 6 tested samples (3 samples are stamped out parallel to the production
direction of USP and 3 samples perpendicular to the production direction of USP).
The supplier shall provide a reference value of tensile strength and the range of purchaser’s acceptance
values.
5.3.3 Static and low frequency dynamic vertical stiffness (bedding modulus) of USP with concrete
block determined with GBP
The static and the low frequency dynamic vertical stiffness (bedding modulus) of USP with GBP permit to
quantify a vertical stiffness (bedding modulus) of the USP without the influence of manufacture of the
sleepers.
Test arrangement:
The static and low frequency dynamic vertical stiffness of concrete block with USP with GBP shall be
measured in accordance with the Annex C.
The low frequency dynamic stiffness and low frequency dynamic bedding modulus is measured at 4 Hz ±1 Hz
and 10 Hz ±1 Hz (and optional frequency tests at 20
