Surfaces for sports areas - Synthetic turf and needle-punched surfaces primarily designed for outdoor use - Part 4: Specification for shockpads used with synthetic turf, needle-punch and textile sports surfaces

This document specifies minimum performance and durability requirements for shockpads used within synthetic turf and textile sports surfacing systems.
The document also specifies appropriate performance tolerance for production and on-site quality control procedures.
This document does not cover structural properties of shockpads. Where appropriate, compliance with other European or national standards and guidelines for these aspects should be followed.
NOTE 1 The sports performance characteristics of a sports surfacing system are provided by the combined characteristics of the playing surface, any infill within the playing surface and the shockpad. The selection of the correct combination of each is complex and the responsibility of the sports surface system designer. It is important to take this into account when considering the performance of a shockpad. A shockpad alone is not be expected to satisfy the performance requirements of the complete sports surfacing system as specified in EN 15330-1, E, etc.
NOTE 2 Some forms of innovative shockpad are designed to provide additional functions beyond aiding the provision of the required sports performance properties. Some of these additional functions can, by design, mean that full compliance with all requirements of this document is not appropriate.
NOTE 3 This document only refers to the shockpad. It makes no recommendations on sub-base constructions or the different synthetic turf for needle-punch textile sports surface designs.
NOTE 4 Annex E (informative) can be used in those countries where national guidance or regulations are not available. If such guidance or regulations are available, they supersede Annex E.

Sportböden - Überwiegend für den Außenbereich hergestellte Kunststoffrasenflächen und Nadelfilze - Teil 4: Festlegungen für Elastikschichten, die in Kunststoffrasenflächen, Nadelfilzen und textilen Sportbelägen eingesetzt werden

Dieses Dokument legt die Mindestanforderungen an die Leistung und Dauerhaftigkeit für Elastikschichten innerhalb von Sportböden fest. Es gilt für alle Arten von Elastikschichten, die als elastische Komponente in Sportböden verwendet werden.
Das Dokument legt auch eine angemessene Ansprechtoleranz für Verfahren zur Qualitätslenkung bei der Produktion und vor Ort fest.
Dieses Dokument behandelt nicht die strukturellen oder Wasserableiteigenschaften von Elastikschichten. Gegebenenfalls sollte die Einhaltung anderer europäischer oder nationaler Normen und Richtlinien für diese Aspekte befolgt werden.
ANMERKUNG 1   Die sportlichen Leistungseigenschaften eines Sportbodens ergeben sich aus den kombinierten Eigenschaften der Spielfläche, aller Füllungen innerhalb der Spielfläche und der Elastikschicht. Die Auswahl der jeweiligen richtigen Kombination ist komplex und liegt in der Verantwortung des Konstrukteurs des Sportbodens. Hinsichtlich der Leistung einer Elastikschicht ist es wichtig, das zu berücksichtigen. Es ist nicht zu erwarten, dass eine Elastikschicht allein die Leistungsanforderungen des gesamten Sportbodens nach EN 15330 1, EN 15330 2, EN 14877 oder EN 14904 usw. erfüllt.
ANMERKUNG 2   Dieses Dokument bezieht sich nur auf die Elastikschicht. Es gibt keine Empfehlungen zu Unterbaukonstruktionen oder zu den verschiedenen Kunstrasen-, Nadelfilz- und textilen Sportbelägen.
ANMERKUNG 3   Anhang E wird in den Ländern angewendet, in denen keine nationalen Leitlinien oder Vorschriften zur Verfügung stehen. Wenn derartige Leitlinien oder Vorschriften zur Verfügung stehen, ersetzen sie Anhang E. 1
1 CCMC empfiehlt, diese ANMERKUNG während der Umfrage sorgfältig zu validieren.

Sols sportifs - Surfaces en gazon synthétique et surfaces en textile aiguilleté principalement destinées à l'usage en extérieur - Partie 4 : Spécifications relatives aux couches de souplesse utilisées avec les sols sportifs en gazon synthétique, en textile et en textile aiguilleté

Le présent document spécifie les exigences minimales de performance et de durabilité applicables aux couches de souplesse utilisés sur les systèmes sols sportifs en gazon synthétique et en textile.
Le présent document spécifie également la tolérance de performance appropriée pour la production et les procédures de contrôle qualité sur site.
Le présent document ne traite pas des propriétés structurelles des couches de souplesse. Il convient, le cas échéant, de se conformer aux autres lignes directrices et Normes européennes et nationales relatives à ces aspects.
NOTE 1 Les caractéristiques de performance sportive d'un système sol sportif sont fournies par les caractéristiques combinées de la surface de jeu, de tout remplissage à l'intérieur de la surface de jeu et de la couche de souplesse. Choisir la bonne combinaison de chacun de ces éléments est une tâche complexe qui incombe au concepteur de système sol sportif. Il est important d'en tenir compte lors de l'appréciation des performances d'une couche de souplesse. À elle seule, une couche de souplesse n'est pas tenue de satisfaire aux exigences de performance du système sol sportif complet tel que spécifié dans l'EN 15330 1, E, etc.
NOTE 2 Certaines formes de couches de souplesse innovantes sont conçues pour assurer des fonctions supplémentaires en plus de faciliter l'obtention des propriétés de performance sportive requises. Pour certaines de ces fonctions supplémentaires, de par leur conception, une conformité totale à l'ensemble des exigences du présent document peut ne pas se révéler appropriée.
NOTE 3 Le présent document se rapporte uniquement à la couche de souplesse. Il ne formule aucune recommandation au sujet des constructions des couches de fondation ou des différents gazons synthétiques pour les conceptions de sols sportifs en textile aiguilleté.
NOTE 4 L'Annexe E (informative) peut être utilisée dans les pays où il n'existe aucune recommandation ou réglementation nationale. Si ces recommandations ou réglementations existent, elles remplacent l'Annexe E.

1 Scope

This document specifies minimum performance and durability requirements for shockpads within sports

surfacing systems. It applies to any type shockpad used as an elastic component in sports surfacing

system.

The document also specifies appropriate performance tolerance for production and on-site quality

control procedures.

This document does not cover structural or drainage properties of shockpads. Where appropriate

compliance with other European or national standards and guidelines for these aspects, should be

followed.

NOTE 1 The sports performance characteristics of a sports surfacing system are provided by the combined

characteristics of the playing surface, any infill within the playing surface and the shockpad. The selection of the

correct combination of each is complex and the responsibility of the sports surface system designer. It is important

to take this into account when considering the performance of a shockpad. A shockpad alone is not be expected to

satisfy the performance requirements of the complete sports surfacing system as specified in EN 15330-1,

EN 15330-2, EN 14877 or EN 14904, etc.

NOTE 2 This document only refers to the shockpad. It makes no recommendations on sub-base constructions or

the different synthetic turf for needle-punch textile sports surface designs.

NOTE 3 Annex E is used in those countries where national guidance or regulations are not available. If such

guidance or regulations are available, they supersede Annex E.

oSIST prEN 15330-4:2020
prEN 15330-4:2020 (E)
4.3.2 Procedure for wet tests

Wet test conditions shall be produced by immersing the shockpad in water to a depth of at least 10 mm

above the top of the shockpad. After a minimum of 30 min, remove the tests specimen from the water

and place it on a free draining base to allow it to drain by gravity for (5 ± 2) min. Test the specimen for

the appropriate property within a further (15 ± 2) min.
4.3.3 Procedure for tests at elevated (40 °C) temperature

Place the shockpad test specimen in an air circulating oven conforming to ISO 188, at a temperature of

(47,5 ± 2,5) °C. After (120 ± 5) min, remove the tests specimen from the oven. Place the test specimen on

the test floor and allow it to cool. Monitor its temperature using a digital temperature probe inserted into

the test specimen. When the temperature probe reads (42 ± 0,5) °C, make a measure. Move the apparatus

and repeat to obtain three results ensuring the temperature of the test specimen does not fall below 38 °C.

4.3.4 Procedure for tests at sub-ambient (5 °C) temperature

Place the shockpad test specimen in a conditioning cabinet at a temperature of −10 °C to 0 °C. After

(120 ± 5) min, remove the tests specimen from the conditioning cabinet. Place the test specimen on the

test floor and allow it to warm. Monitor its temperature using a temperature probe inserted into the test

specimen. When the temperature gauge reads 5 °C, make a measure. Move the apparatus and repeat to

obtain three results ensuring the temperature of the test specimen does not rise above 7 °C.

4.3.5 Procedure for accelerated air ageing

Following accelerated air ageing undertaken in accordance with EN 13817, the sample shall be tested

under standard laboratory conditions.
4.3.6 Procedure for tests under freezing (−5 °C) conditions

Immerse the shockpad in water to a depth of at least 10 mm above the top of the shockpad. After a

minimum of one hour, remove the tests specimen from the water and place it on a free draining base to

allow it to drain by gravity for (30 ± 2) min before placing the test specimen in a conditioning cabinet at

a temperature of −8 °C to −12 °C. After (240 ± 5) min, remove the tests specimen from the conditioning

cabinet. Place the test specimen on the test floor and allow it to warm. Monitor its temperature using a
