1 Scope
This document specifies minimum performance and durability requirements for shockpads used within
synthetic turf and textile sports surfacing systems.
The document also specifies appropriate performance tolerance for production and on-site quality
control procedures.
This document does not cover structural properties of shockpads. Where appropriate, compliance with
other European or national standards and guidelines for these aspects should be followed.
NOTE 1 The sports performance characteristics of a sports surfacing system are provided by the combined
characteristics of the playing surface, any infill within the playing surface and the shockpad. The selection of the
correct combination of each is complex and the responsibility of the sports surface system designer. It is
important to take this into account when considering the performance of a shockpad. A shockpad alone is not be
expected to satisfy the performance requirements of the complete sports surfacing system as specified in
EN 15330-1, E, etc.
NOTE 2 Some forms of innovative shockpad are designed to provide additional functions beyond aiding the
provision of the required sports performance properties. Some of these additional functions can, by design, mean
that full compliance with all requirements of this document is not appropriate.
NOTE 3 This document only refers to the shockpad. It makes no recommendations on sub-base constructions or
the different synthetic turf for needle-punch textile sports surface designs.
NOTE 4 Annex E (informative) can be used in those countries where national guidance or regulations are not
available. If such guidance or regulations are available, they supersede Annex E.

4 Laboratory conditions and specimen conditioning
4.1 Test floor
Shock absorption and deformation tests shall be made on a rigid concrete floor concrete comprising a
rigid, non-vibrating, smooth, level and even concrete floor on which a peak force (Fmax) of (6,60 ± 0,25)
kN is achieved.
The shockpad shall be attached to the concrete floor using (50 ± 5) mm wide double-sided adhesive
tape. This shall be attached to the outer edges of the test specimen.
4.2 Test environments
As specified tests shall be carried out under the conditions detailed in Table 1.

NOTE The load spreading plate is designed to partly replicate the lateral impact dissipation provided by the
synthetic turf or textile sports surface that is laid over the shockpad.
4.3 Procedure for test specimen conditioning
4.3.1 Standard laboratory conditions
Unless otherwise specified tests shall be undertaken under standard laboratory tests conditions of
(23 ± 2) °C. The test specimen shall be conditioned for a minimum of 3 h at the specified temperature
prior to test.
NOTE As shockpads are generally not sensitive to humidity, it is not considered necessary to specify strict
humidity conditions for the laboratory. Nevertheless, it is advisable for the humidity to be nominally 50 % RH.

SIST EN 15330-4:2023
EN 15330-4:2022 (E)
4.3.2 Procedure for wet tests
Wet test conditions shall be produced by immersing the shockpad in water to a depth of at least 10 mm
above the top of the shockpad. After a minimum of 30 min, remove the tests specimen from the water
and place it on a free draining base to allow it to drain by gravity for (5 ± 2) min. Test the specimen for
the appropriate property within a further (15 ± 2) min.
4.3.3 Procedure for accelerated air ageing
Following accelerated air ageing undertaken in accordance with EN 13817, the specimen shall be tested
under standard laboratory conditions.
4.3.4 Procedure for tests at elevated (40 °C) temperature
Place the shockpad test specimen in an air circulating oven conforming to ISO 188, at a temperature of
(47,5 ± 2,5) °C. After (120 ± 5) min, remove the tests specimen from the oven. Place the test specimen
on the test floor and allow it to cool. Monitor its temperature using a digital temperature probe inserted
into the test specimen. When the temperature probe reads (42 ± 0,5) °C, make a measure. Move the
apparatus and repeat to obtain three results ensuring the temperature of the test specimen does not fall
below 38 °C.
4.3.5 Procedure for tests at sub-ambient (5 °C) temperature
Place the shockpad test specimen in a conditioning cabinet at a temperature of −10 °C to 0 °C. After
(120 ± 5) min, remove the tests specimen from the conditioning cabinet. Place the test specimen on the
test floor and allow it to warm. Monitor its temperature using a temperature probe inserted into the
test specimen. When the temperature gauge reads 5 °C, make a measure. Move the apparatus and
repeat to obtain three results ensuring the temperature of the test specimen does not rise above 7 °C.
4.3.6 Procedure for tests under freezing (−5 °C) conditions
Immerse the shockpad in water to a depth of at least 10 mm above the top of the shockpad. After a
minimum of one hour, remove the tests specimen from the water and place it on a free draining base to
allow it to drain by gravity for (30 ± 2) min before placing the test specimen in a conditioning cabinet at
a temperature of −8 °C to −12 °C. After (240 ± 5) min, remove the tests specimen from the conditioning
cabinet. Place the test specimen on the test floor and allow it to warm. Monitor its temperature using a
temperature probe inserted into the test specimen. When the temperature gauge reads −5°C ± 0,5 °C,
make a measurement. Move the apparatus and repeat to obtain three results ensuring the temperature
of the test specimen does not rise above −3 °C.
4.3.7 Test positions
Tests undertaken at (23 ± 2) °C shall be made in three test positions, each 200 mm apart and at least
100 mm from the sides of the test specimen.
For tests undertaken at non-ambient laboratory conditions one series of measurements shall be made
at least 100 mm from the sides of the test specimen.
5 Load spreading plate
As a shockpad’s performance can be influenced by the how an impact force is applied to it (e.g. an
unrepresentative direct vertical loading can cause an excessive compression and loss of performance),
certain tests (as specified in Clause 6) shall be made with and without a load spreading plate. The load
spreading plate shall be as described in Table 2.
