(Main)Surfaces for sports areas - Test method for the determination of tensile properties of synthetic sports surfaces
Surfaces for sports areas - Test method for the determination of tensile properties of synthetic sports surfaces
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.
NOTE 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.
Sportböden - Prüfverfahren für die Bestimmung der Zugfestigkeitseigenschaften von Kunststoffflächen
Dieses Dokument legt drei Verfahren zur Bestimmung der Zugfestigkeitseigenschaften von Materialien fest, die als Oberflächen, nachgiebige Lagen und Elastikschichten für Sportböden eingesetzt werden.
Mit Verfahren 1 wird die Zugfestigkeit homogener Probekörper mit einer Dicke von weniger als 25 mm gemessen.
Mit Verfahren 2 wird die Zugfestigkeit homogener Probekörper mit einer Dicke von mehr als 25 mm gemessen.
Mit Verfahren 3 wird die Zugfestigkeit von Sportböden oder Elastikschichten gemessen, die nicht homogen sind und deren Aufbau Spalte oder Rillen aufweist.
Dieses Dokument gilt sowohl für vorgefertigte Materialbahnen als auch für Materialien, die vor Ort durch Gießen von flüssigen Bestandteilen und Härten hergestellt werden.
ANMERKUNG Wenn die Art des Sportbodens verhindert, dass ein repräsentativer Probekörper nach den Angaben in diesem Dokument hergestellt werden kann, so sollte keine Bestimmung der Zugeigenschaften zur Qualitätsüberwachung oder als Voraussage für die Leistungsfähigkeit beim Gebrauch unternommen werden. Bei solchen Materialien kann es angemessener sein, für diese Zwecke die Druckfestigkeit oder andere dynamische Eigenschaften zu bestimmen.
Sols sportifs - Méthode d’essai pour la détermination des caractéristiques de traction des surfaces sportives synthétiques
Le présent document spécifie trois méthodes de détermination des caractéristiques de traction des matériaux utilisés dans la fabrication de surfaces, de couches élastiques et de couches de souplesse pour les terrains de sport.
La méthode 1 mesure la résistance à la traction d’éprouvettes homogènes de moins de 25 mm d’épaisseur.
La méthode 2 mesure la résistance à la traction transversale d’éprouvettes homogènes de plus de 25 mm d’épaisseur.
La méthode 3 mesure la résistance à la traction des surfaces sportives ou des couches de souplesse qui ne sont pas homogènes et qui contiennent des fentes ou des rainures découpées dans leur structure.
Ce document est applicable à la fois aux matériaux en couches préfabriquées et aux matériaux moulés par coulage de systèmes liquides polymérisés sur site.
NOTE Si la nature de la surface sportive ne permet pas de préparer d’éprouvette réellement représentative suivant le mode opératoire décrit dans le présent document, il convient de ne pas envisager de déterminer les caractéristiques de traction aux fins d’un contrôle de la qualité, ni pour prévoir les performances à l’utilisation. Dans le cas de tels matériaux, il peut se révéler plus approprié, dans cette optique, de déterminer les caractéristiques de compression ou toute autre caractéristique dynamique.

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.---------------------- Page: 6 ----------------------

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; andd) if an extensometer is used, it exerts a minimum force on the test specimen and elongation of the test
specimen may 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
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.
4.3 Test specimens4.3.1 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 4.3.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 specimen using the thickness gauge (4.2.2) and a
measurement force of between 0,8 N and 1,0 N. Measure the thickness of the test piec
