Introduction
General
Synthetic turf sports surfaces provide attractive, hard–wearing and safe playing areas that
can accommodate high levels of use and be used in far more diverse climates than natural
turf. The development of these surfaces has led to significant demand with over 16 000 full
size sports fields now being used in Europe, and approximately 4 000 new fields being built
each year.
Synthetic turf sports surfaces take four generic forms:
— non-filled short pile;
— sand filled or sand dressed short pile;
— long pile with infill (typically rubber and/or sand);
— long pile non-filled.
Infill is applied to the synthetic turf surfaces for three reasons:
— it is used to stabilize the carpet to prevent dimensional expansion and contraction and
movement through use i.e. it acts as a ballast. This type of infill is often described as
stabilizing infill;
— it contributes or provides the sports performance and impact attenuation
characteristics of the sports surface. This type of infill is often described as
performance infill. The performance infill is a key component of the surface as it
provides comfort and protection to players as they run and fall on the surface;
— it helps control the way the ball interacts with the surface, supporting the pile of the
surface so it remains upright.
Short pile synthetic turf surfaces typically have pile heights of between 10 mm and 30 mm
and normally only have one layer of infill. This is often a rounded sand. Sometimes the sand
has a polymeric coating to change the colour of the infill (i.e. it is coloured to match the
synthetic turf colour).
Figure 1 shows the typical cross section of a short pile synthetic turf sports surface.

Long pile synthetic turf surfaces typically have pile heights of between 30 mm and 60mm.
Most contain two layers of infill, the lower layer (normally sand) is installed to provide
ballast and stability to prevent the synthetic turf carpet moving. The upper layer is the
performance infill.
There are a number of different granulated materials used to form this layer including
various rubbers and thermo-plastics and natural materials such as cork, timber, nut husks,
etc.

Most infills are in the particle size range 0,5 mm to 2,5 mm with some occasionally being
larger.
Environmental concerns
Increasing public concern about microplastics has led the European Commission, to
investigate ways of reducing the quantities released into the environment. They have
defined a microplastic as any solid particle made of a non-biodegradable polymer that is
5,0 mm or less in size. They can be unintentionally formed through wear and tear or
deliberately manufactured and intentionally added to products for a specific purpose.
As many infill materials used within synthetic turf sports surfaces are either made from
non-bio-degradable polymers that are less than 5,0 mm in size, or incorporate some form
granule (e.g. sand) that has a polymeric coating, it is important that the design and
maintenance of sports fields having these infills is undertaken in a way that minimizes the
possibility of the infill migrating from the sports surface and being dispersed into the
environment. This document describes ways of containing infill materials within the
footprint of the synthetic turf field during its construction, operation and end of life
removal.
1 Scope
This document describes ways of containing infill materials used in many types of synthetic
turf sports fields within the confines of the sports field, so they are not dispersed into the
surrounding environment.
The options described are based on examples of best practice identified by members of
CEN/TC 217.
This document is intended to be of practical use, to create awareness amongst field
designers, venue owners, installation companies and those maintaining synthetic turf
sports fields. It is applicable for all forms of synthetic turf sports field, from those used for
community activities to those used by professional and elite level athletes.

all components of the surface that influence its sports performance or bio-mechanical
characteristics including the synthetic turf carpet, infill and shockpad
3.2
filled synthetic turf
synthetic turf surface, whose pile is either totally filled or partly filled with an unbound
particulate material
3.3
infill
particulate materials used within the synthetic turf surface to provide support to the carpet
pile and to aid the provision of the required performance characteristics of the surface
3.4
performance infill
granulated materials used to form the upper layer of infill that help provide the required
sports performance and player welfare characteristics of the surface
3.5
polymeric infill
granular infill material formed from non-biodegradable rubbers or plastics, or an infill
material that has a coating formed from non-biodegradable rubbers or plastics (e.g. coated
sand)
3.6
stabilizing infill
particulate materials used to infill the lower portion of the synthetic turf surface to provide
support to the carpet pile and ballast to hold the carpet in place and help prevent
dimensional movement
3.7

length multiplied by the spacing (gauge) of the tufting needles
3.9
field
playing area including the perimeter margins or run offs
Note 1 to entry: Field is also known as the pitch.
3.10
base
all elements of construction beneath the synthetic turf sports surfacing system
4 Sports performance
The performance of a synthetic turf sports surface is provided by the interactions of the
synthetic turf carpet, the infill materials and, if part of the system, the shockpad.
Occasionally some synthetic turf systems also utilize characteristics of the base
construction to achieve the required performance.
EN 15330-1 specifies the properties required of synthetic turf surfaces used for football,
rugby, hockey, tennis and multi–sports applications. The requirements of EN 15330-1 are
intended to apply to surfaces used for community, educational and recreational sport. For
professional and elite levels of competition, many sports governing bodies have published
their own specifications.
NOTE The requirements of the sports’ governing bodies differ from those detailed in
EN 15330-1 and facility developers are advised to ensure that they select surfaces offering the
correct performance for the level of competition to be played on the field.
5 Infill migration routes
Experience has shown that infill materials can be transported from a synthetic turf field by
a number of different actions including:
— being carried by players (caught in and stuck on clothing and footwear);
— snow removal;
— being carried by maintenance equipment;
— inappropriate maintenance procedures;
— inappropriate installation procedures;
— poor storage of spare material;
— surface water run–off from the field;
— wind dispersion.
6 Means of minimizing infill migration
6.1 General
By incorporating appropriate design features into a synthetic turf sports field and
undertaking its construction, operational maintenance and end-of-life removal in
environmentally sensitive ways the risk of infill being dispersed from within the field to the
surrounding environment can be minimized.
The following clauses describe examples of good practice that have been shown to be
effective in ensuring infills are not dispersed into the surrounding environment. Many of
these design features work best when used in collectively and it should not be assumed that
only incorporating one feature will achieve the desired containment.
