Introduction
To respond to the needs of buyers, end users and installers of synthetic sport systems for outdoor as well as
to respond to the needs of producers of granulate as system constituents, CEN/TC 217 Working Group
"Environmental Aspects" (WG 10) has worked on the following principles:
Firstly, define a laboratory test designed to assess the release of substances in ground water from a complete
"synthetic sport system for outdoor". The method of this test is based on the principle of large-scale in-situ
tests (lysimeters). This test uses a sample of a sport surface similar to the sample used for laboratory type
tests and representative of the system that will be installed.
Secondly, make it possible for integrators to assess specific leaching characteristics of relevant components
and anticipate the results of the above laboratory test, specifying testing standards for a relative leaching
assessment of system’s constituents of different origins or nature, for instance granules (see Annex A).
NOTE This Technical Specification is based on the available knowledge and expertise. It is expected that it will be
used in a harmonised way by the European Laboratories during the first three-years period and that this will result in an
extended experience. Based on such experience, it is expected that the Technical Specification could be improved and
transformed into an EN standard.
This document includes one normative annex and one informative annex. Additional information will be found
in a guidance document in preparation.

5 Principle
The principle of this test is to simulate the phenomena observed on outdoor synthetic sport systems. It
ensures, in particular, a short contact time between the synthetic sport system and water, corresponding to
the draining function of this surfaces. The spraying system is conventionally adjusted to alternate particularly
dry and wet periods. Prior to the test performance, the sample may be submitted to standardised aging.
Therefore in the testing report, it has to be noted if the sample was subjected to aging or not. If the sample
was subjected to aging, the test used for the aging has to be mentioned as well.
NOTE The sample is of the same type as the one used for mechanical test and ensures testing on significant
quantities of tested materials (EN 15306).
6 Apparatus and reagents
6.1 General
This clause defines the apparatus and reagent to be used. This is mainly done in normative terms. Therefore
the informative Annex B provides an example of apparatus that meet the requirements specified in this clause.
6.2 Tank
The tank (see Figure 1) and the vertical supports that allow the adjustment of rods and guide rods of the
watering ramp are made of stainless steel or polycarbonate. The materials and fabrication method has to be
such that the result of the blank test fulfils the requirements specified in 7.2. The tank dimensions are as
follows: L = 800 mm (+/- 5 mm), W = 400 mm (+/- 5 mm), H = 150 mm and 160 mm (to slope the bottom a
little) similar to the dimensions in EN 15306. A hole is drilled at the bottom point for the passage of the
percolate drain pipe.
6.3 Watering system
The watering system is aiming at wetting in an homogeneous way the sample by means of a spraying system
(see Figures 1 and 2) which consists of 8 full cone spraying nozzles attached to each of the guiding rods.
These nozzles are selected and arranged so that
a) the diameter of the spray on the sample surface has a diameter of 200 mm – 250 mm in order to obtain a
complete coverage (see Figure 3).

Figure 2 — Functional diagram - Transverse view (informative)
b) The spraying system is fed by a moving device (see Figure 1) either a dosing pump connected to a
storage tank of water or a pressurised (with clean compressed air) storage tank of water. The water flow
shall be maintained at the required flow ± 10 %.
c) The required flow shall be achieved with a water pressure at the spray nozzle in the range 1,4 bar –
1,6 bar, without visible haze. A cover may be used to minimise air draught and water carry over.
d) The quality of this water shall be in accordance with the following specification: Distilled water,
demineralised water, de-ionised water or water of equivalent purity with a conductivity < 0,5 mS/m
according to grade 3 specified in EN ISO 3696, and exhibiting a pH in a narrower range (6,5 < pH< 7,5)
than the range of grade 3 specified in EN ISO 3696. If needed a dilute solution of sodium hydroxide may
be used to adapt the pH range.
NOTE 1 This specification is defined as a convention relevant for the exposure of synthetic sport system. The
experimental set up specified in this Technical Specification allows a relevant selection of the leachant since it is
continuously renewed and therefore exposing the sample to the same liquid quality during the whole test. In order to
secure repeatable and comparable results a selection of leachant should be made. The above specification is used in
several CEN leaching standards with pH range (5 < pH < 7,5) which do not influence the leaching results under permanent
and long lasting contact with the leachant. Such leaching tests are aiming at an equilibrium generally imposed by the
sample. For synthetic sport systems a narrower pH range is needed (6,5 < pH < 7,5). The reason is that the pH is not
influenced significantly during the short and intermittent contact with the leachant, due to the main function of the synthetic
sport system securing a very fast water drainage.
NOTE 2 An impact of the surface tension of the leachant has been reported. It is therefore wise to determine and
report this surface tension.
The "synthetic sport" system is laid on top of the stainless steel grid.
This grid is designed in order to avoid immersion of the synthetic sport sample and to facilitate drainage.
The selected spray nozzles shall have a maximum spraying angle of 110° (full cone angle) and a minimum
spraying angle of 40° (full cone angle). This corresponds to a minimum height between the spray nozzles and
the sport surface.
Qualification tests shall be carried out on the apparatus to verify that the spray pattern is homogeneous over
the entire surface by checking the flow rate of each spray nozzle (e.g. by placing cups on the sport surface).

Figure 3 — Functional diagram - Spraying surface (informative)
A "blank test" is to be performed without the synthetic sport system to verify that the impact of the apparatus
on the percolates is significantly below the regular test results.
6.4 Choice and quantity of tested materials
The tested system is representative for the system defined by the system supplier. It integrates all the
components used on a “synthetic sport” system as specified by the system supplier.
For example, for a synthetic sport system for outdoor and with performance infill, the elements to be
considered are the following:
• The fibres, backing and coating: The sample integrates a white strip (marking line on the grounds)
and the glue if it is present on the marketed system.
• The performance infill: To ensure the representativeness of the material, a representative sample
has to be taken.
• The stabilising infill: To guarantee representativeness, the tested sample shall be representative of
the production intended for the “synthetic sport” system
• The shockpad: The dimensions 800 mm x 400 mm are assumed to be representative of the
production intended for a large-scale “synthetic sport” system.
7 Procedure
7.1 Testing conditions
7.1.1 Frequency/duration of the spraying/non-spraying periods and the flow rate
2
For a week there are two days without spraying and five days with spray twice a day (each of 10 L/m i.e. 3,2
L = 0,4 L per nozzle and per spray) with the non-spraying period of each day being at least 6 h and less than
6 h and 15 min. The duration of each spraying period shall be at least 45 s and less than 120 s
NOTE  This amount can be split over two weeks. Each week would consist of five consecutive days with spraying
and two days without spraying and consequently without collection of percolate. For each day there would be two sprays,
2
each of 10 L/m (i.e. 3,2 L) with the non-spraying period of each day being at least 6 h and less than 6 h and 15 min.

SIST-TS CEN/TS 16384:2013
CEN/TS 16384:2012 (E)
7.1.2 Experiment duration
The duration of the experiment is two weeks
NOTE The number of weeks should take into account the time needed in the field to reach a "plateau" in the release.
For instance a French study has shown a stabilisation of the results after a duration of 3 months. Also to be noted that,
2
assuming 15 kg/m of granules, the liquid/solid ratio will be 13 after these two weeks].
7.1.3 Kind of sprayed water as leachant
The kind of sprayed water as leachant should be as specified in 6.2.
7.1.4 Taking and sampling of collected percolates
A liquid sample is taken from the 64 l in the collecting tank, in accordance with EN ISO 5667-3 at the end of
the second week, between 15 min and 30 min after the last spraying period, for analysis in accordance with
EN 12506 and EN 13370. Additionally samples can be taken during each spray and analysed separately to
verify the stabilisation over time.
NOTE 1 In the analytical standard EN 12506, standardised analytical methods are selected for the determination of pH,
As, Ba, Cd, Cl-, Co, Cr, Cr Vl, Cu, Mo, Ni, NO2-, Pb, total S, SO42-, V and Zn. In the analytical standard EN 13370,
standardised analytical methods are selected for the determination of Ammonium, AOX, conductivity, Hg, phenol index,
TOC, easily liberatable CN-, F-. An example of selected analytical method is EN ISO 11885. In the preparation standard
EN 15002, guidance is given on the preparation of test portions from the laboratory sample i.e. the sample collected on
the testing device as specified above.
NOTE 2 The above notes do not mean that all the above substance are to be determined. They only mean that there are
available analytical methods for determining such substances that are specified in the prevailing regulation or in the test
specification given by the customer to the testing laboratory.
7.1.5 Temperature and humidity conditions and storage
Laboratory temperature 23 °C ± 2 °C with relative humidity 50 % ± 5 % and water to be sprayed 23 °C ± 2 °C.
The components have to be stored in the laboratory at least for 12 h before the start of the test.
7.2 Preliminary tests
Blank test: A full test will be held without the synthetic sport system sample to check that the impact of the
apparatus on the percolates will be less than 10 % of the test result. The water collected will be analysed
accordingly.
NOTE 1 In case of positive consecutive blank tests, a blank test may be omitted. However a subsequent negative
blank test would compromise the regular test(s) not immediately following a blank test.
Before the start of the test, the synthetic sport system shall be sprayed with three spraying periods without
stops.
NOTE 2 It has been considered that this amount will be for most cases enough so that saturation is reached and so
that a stabilised flow is reached at the outlet of the system.
8 Synthetic sport systems for outdoor with no permeability capabilities
In case when the synthetic sport system for outdoor exhibit no draining capabilities in accordance with
EN 14877 and EN 15330-1, the test specified in the above clauses shall be used with a slope of 1 %. One of
the side of 40 cm is selected to be the higher point while the other one is complemented with a grove to collect
the running water that is not penetrating the sample of synthetic sport system.

Annex A
(normative)

Test of component (e.g. granule) of a synthetic sport system
for outdoor use
A.1 Introduction
As indicated in the introduction of this Technical Specification, this annex describes three procedures that
have been proposed for a relative leaching assessment of system’s components (e.g. granules) of different
origins or nature. This is intended on the one hand to facilitate production control of components and on the
other hand to make possible for integrators to anticipate the results of the "reference" method described in the
main part of this standard. Use of such indirect method requires that in the framework of this standard
appropriate information is available on their comparability/traceability to the standardised "reference" method
described in the main part of this standard.
NOTE 1 In the framework of this Technical Specification, these methods provides relative leaching assessment by
establishing a typical "no change" situation in production control or in changing the type of granules. However, this
information may be misleading if the indirect method is not sensitive enough to the real changes being considered.
