Tests for mechanical and physical properties of aggregates - Part 9: Determination of the resistance to wear by abrasion from studded tyres - Nordic test

EN 1097-9 describes the reference method, used for type testing and in case of dispute, for determination of the resistance of coarse aggregate to wear by abrasion from studded tyres. For other purposes, in particular factory production control, other methods may be used, provided that an appropriate working relationship with the reference method has been established. The test is applicable to aggregates with a size fraction of 11,2 mm to 16 mm.

Prüfverfahren für mechanische und physikalische Eigenschaften von Gesteinskörnungen - Teil 9: Bestimmung des Widerstandes gegen Verschleiß durch Spikereifen - Nordische Prüfung

Diese Europäische Norm beschreibt das Referenzverfahren für die Typenprüfung und im Streitfall, für die Bestimmung des Widerstandes der groben Gesteinskörnung gegen Verschließ durch Spikereifen. Für andere Zwecke, insbesondere Produktionskontrolle, dürfen andere Verfahren angewendet werden, sofern ein ausreichender Zusammenhang mit diesem Referenzverfahren nachgewiesen wurde.
Die Prüfung ist für Gesteinskörnungen mit einer Körnung von 11,2 mm bis 16,0 mm anwendbar.
ANMERKUNG    In Anhang A ist eine alternative Kornklasse 8/11,2 mm für verschiedene Verwendungszwecke angegeben.

Essais pour déterminer les propriétés mécaniques et physiques des granulats - Partie 9: Méthode pour la détermination dela résistance à l'usure par abrasion provoquée par les pneusà crampons - Essai scandinave

La présente Norme européenne décrit la méthode de référence utilisée pour les essais de type et en cas de litige pour déterminer la résistance des gravillons à l’usure par abrasion provoquée par les pneus à crampons. À d’autres fins, en particulier pour la maîtrise de la production des granulats, d’autres méthodes peuvent être utilisées, à condition qu’une corrélation appropriée avec la méthode de référence ait été établie.
L’essai est applicable aux granulats de fraction granulométrique comprise entre 11,2 mm et 16 mm.
NOTE   Une fraction granulométrique alternative 8/11,2 mm destinée à des utilisations différentes est fournie en Annexe A.

EN 1097-9:2014 (E) 3 Foreword This document (EN 1097-9:2014) has been prepared by Technical Committee CEN/TC 154 “Aggregates”, the secretariat of which is held by BSI. 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 2014 and conflicting national standards shall be withdrawn at the latest by July 2014. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 1097-9:1998. The main technical changes compared to EN 1097-9:1998 are the following: 1) Scope: rewritten to allow the use of other methods under precise conditions; 5) Apparatus: Possibility to use other suitable equipment for drying aggregates than the prescribed ventilated oven. Steel quality has been updated; 6) Preparation of test specimens: rewritten (Mass of test portion: Formula revised, Loading the drum: Order changed); 8) Calculation and expression of results: the re-testing criteria has been amended and supplemented with Dixon test guidelines; 9) Test report: required and optional data have harmonized according to document CEN/TC 154/SC 6 – N 1120.
