14904 Indoor surfaces for multi-sports use
Only reference standards for sports floorings
European Standard (EN 14904:2006) was developed by
the Technical Committee CEN/TC 217 "Surfaces for
sports areas", whose secretariat is managed by BSI.
The European standard shall be given the status of
National Italian Standard since October 2006, and
all other national conflicting standards must have
been withdrawn within October 2006.
The European Standard has been processed within a
task assigned to CEN by the European Commission and
by the European Free Trade Association, and supports
the essential requirements set by the European Union
According to the CEN/CENELEC Internal Regulations,
the National Standards Organizations of the
following countries are bound to implement the
European Standard: Austria, Belgium, Cyprus,
Denmark, Estonia, Finland, France, Germany, Greece,
Ireland, Iceland, Italy, Latvia, Lithuania,
Luxembourg, Malta, Norway, Netherlands, Poland,
Portugal, United Kingdom, Czech Republic, Romania,
Slovakia, Slovenia, Spain, Sweden, Switzerland and
Sports surfaces go through a complex reaction when
subjected to dynamic loading.
The desired components of the interaction are
deformation under load, ability to absorb impact,
and energy return of the impact, for instance the
amount of energy returned to a sportsman from the
surface on which he/she is playing. The power of a
surface to absorb an impact is an important safety
feature. The specified values are therefore a
necessary compromise between these essential
features. Sports surfaces react differently under
different temperatures and strain rates; they get
harder at low temperatures and softer at high
An important requirement for safety and sports
performance is for there to be enough grip between
the athlete’s footwear and the sports surface.
Inadequate grip can cause the athlete slipping on
the surface; too much grip can put unacceptable
stress on joints and muscle ligaments.
Here are the key points of this Standard,
obviously going back to the former German Standard
DIN 18032, which can be appointed as the source of
the current EN Standard for indoor surfaces.
Friction EN 13036-4
When tested by the method described in EN 13036-4,
using CEN rubber under
dry conditions at a temperature of (23 ± 2) °C, the
mean of the pendulum test value shall be between
80 e 110 and no individual test result shall differ
from the mean by more than 4 units.
Shock absorption EN 14808
When tested by the method described in EN 14808,
carrying out a minimum of four tests plus one test
for every 500 m2 of area, the mean force reduction
shall be between 25% and 75% and no individual
result shall differ from the mean by more than ±5
Vertical deformation EN 14809
When tested by the method described in EN 14809, the
vertical deformation shall not exceed 5,0 mm.
Note 1: These values are laboratory values.
Measurements on site may be carried out at different
temperatures and humidities depending on the ambient
conditions of the sport hall, in which case the
surface temperature and relative humidity should be
recorded in the test report .
Note 2: Information on typical shock absorption and
vertical deformation values foe elastic floors is
given in Annex B.
Vertical ball behavior EN 12235
When tested by the method described in EN 12235
using a basketball, carrying out a minimum of four
tests plus one test for every 500 m2 of area, the
mean relative rebound height shall be ±90% of the
rebound height on concrete and no individual result
shall differ from the mean by more than ± 3 units.
Resistance to rolling load EN 1569
Note This property is important to ensure that the
surface will not be damaged by equipment or seating
that might be moved around.
When tested by the method described in EN 1569, the
minimum resistance shall be 1 500 N, the maximum
indentation shall be 0,5 mm under a 300 mm straight
edge and no perceivable damage shall be observed
after the test.
Resistance to wear EN ISO 5470-1
Note This property is important to ensure a
reasonable expected lifetime in use, particularly
for high usage areas (e.g. areas in front of goal on
ball pitches) which tend to lose material by
For synthetic surfaces, when tested by the method
described in EN ISO 5470-1, using H18 wheels with a
1 kg load, the maximum loss in mass per 1 000 cycles
shall be 1.000 mg.
For coatings and lacquers intended to be applied as
part of scheduled maintenance, when tested by the
method described in EN ISO 5470-1, using CS10 wheels
with a 500 g load, the maximum loss in mass per
1.000 cycles shall be 80 mg.
EN 13501-1 FIRE CLASSIFICATION OF BUILDING
The new standard replaces all the former ones and
sets the classification of the building materials
according to the European standards.
Italy acknowledged the European Standard mainly with
two Decrees. The Italian Ministry of Interior, with
the Decree 15th March 2005 “Requirements of fire
reaction for building elements supplied within
activities regulated by specific technical fire
prevention dispositions according to the European
classification system” and the following Decree 16th
February 2009, making changes and integrations.
For sports floorings with stay of public on the
surface, the table sets the classes (A2FL-s1),
(A2FL-s2), (BFL-s1), (BFL-s2), (CFL-s1), equalized
to the previous Italian “Class 1”.
For floorings the reference tests are:
EN ISO 9239 Fire reaction tests on floorings
EN 11925-2 sets the flame attack on the surface
EN 9239-1 Smoke critical flux evaluation
