European foreword
This document (EN 12230:2023) has been prepared by Technical Committee CEN/TC 217 “Surfaces for
sports areas”, the secretariat of which is held by AFNOR.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by July 2023, and conflicting national standards shall be
withdrawn at the latest by July 2023.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 12230:2003.
Any feedback and questions on this document should be directed to the users’ national standards body.
A complete listing of these bodies can be found on the CEN website.
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia,
Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland,
Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Republic of North
Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Türkiye and the United
Kingdom.
1 Scope
This document specifies three methods for the determination of the tensile properties of materials used
as surfaces, elastic layers and shockpads for sports areas.
Method 1 measures the tensile strength of homogenous test specimens that are less than 25 mm in
thickness.
Method 2 measures the transversal tensile strength of homogenous test specimens that are more than
25 mm in thickness.
Method 3 measures the tensile strength of sports surfaces or shockpads that are non-homogenous and
contain slots or grooves cut into their structure.
This document is applicable both to prefabricated sheet materials and to materials formed by casting of
liquid systems cured in-situ.
If the nature of the sports surface is such that a properly representative test piece cannot be prepared in
the manner described in this document, then determination of tensile properties should not be attempted
for quality control purposes, or as a predictor of performance in use. With such materials, it can be more
appropriate to determine their compressive properties or other dynamic characteristics for these
purposes.

3.1

geometric measure of the roughness of the top of surfacing; the magnitude of regularly or irregularly
recurring vertical deviations of a surface
3.2

3.3

peak load, less 10%
4 Method 1 – Determination of the tensile properties of homogenous test
specimens less than 25 mm thick
4.1 Principle
A test specimen of a given shape is subjected to tensile stress transmitted to it by means of a suitable
device. The resulting stress-strain curve is plotted, from which various parameters are subsequently
deduced.
4.2 Apparatus
4.2.1 Test machine
A test machine, such that:
a) the test specimen may be held in the fixing grips of the test apparatus. These fixing grips shall meet
the following conditions:
1) The test specimen may be held sufficiently tight to avoid slipping.
2) No localized pressure that could tear or rupture the ends is exerted on any part of the test
specimen.
b) under no load the movable grip may be moved away from the fixed grip at a constant speed of (50 ±5)
mm/min in a direction parallel to the longitudinal axis of the test piece;
c) the force exerted on the test specimen may be read with a maximum error of 1 % and may be
recorded; and
d) if an extensometer is used, it exerts a minimal force on the test specimen, and the elongation of the
test specimen shall be read to an accuracy of 0,1 mm.
4.2.2 Thickness gauge
Thickness gauge, accurate to 0,01 mm with a plunger and a flat measuring surface of nominally 4 mm
diameter applied to the surface under a load of (0,9 ± 0,1) N.
4.2.3 Dial gauge and measuring plate
Dial gauge capable of reading to 0,1 mm with a plunger, having a flat circular contact surface with a
diameter of nominally 1,5 mm applied to the surface under a load of (0,9 ± 0,1) N. to be used in
conjunction with a tempered glass plate measuring 80 mm x 80 mm ± 2,0 mm and having a thickness of
4,0 mm ± 0,5 mm and a weight of 60 g +/- 5 g.
4.3 Test specimens
4.3.1 Dimensions
Cut the test specimens in accordance with the shape and dimensions shown in Figure 1.
If the distance between the parallel surfaces of the extensometer gauge length varies by more than 5 %
(tolerance on parallelism), discard the test specimen and cut a further specimen.

4.3.2 Thickness
Ensure that the thickness of the test specimen equals the thickness of the installed surfacing, except in
the following cases, where further preparation is required:
a) Where the thickness of the installed sports surface and/or the sample provided for test is greater
than 25 mm, reduce the thickness of the test specimen by machining or cutting to between 20 mm
and 25 mm, taking care during this operation that the structure of the material is not altered, and the
test specimen remains as representative as possible of the installed sports surface.
b) Where the material carries a surface texture, embossing or granular finish, prepare the upper surface
and underside of the test specimen as described in 4.4.
Preparation of the underside of the test specimen to remove irregularities is necessary, for example,
where a once-liquid system has been removed from a textured or porous substrate.
After preparation, measure the thickness of each test spe
