Tests for geometrical properties of aggregates - Part 6: Assessment of surface characteristics - Flow coefficient of aggregates

This European Standard specifies the reference method used for type testing, and in case of dispute, for determining the flow coefficient of coarse and fine aggregates. 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. Examples of advanced test methods can be found in the Bibliography.
This European Standard applies to coarse aggregate of sizes between 4 mm and 20 mm and to fine aggregate of size up to 2 mm.
NOTE 1   For coarse aggregates between 4 mm and 20 mm, the flow coefficient is linked with the percentage of crushed or broken surfaces of an aggregate and can therefore be used in association with the method specified in EN 933-5. Shape and surface texture characteristics also influence the result.
NOTE 2   Experience of this test has been generally limited to natural aggregates.

Prüfverfahren für geometrische Eigenschaften von Gesteinskörnungen - Teil 6: Beurteilung der Oberflächeneigenschaften - Fließkoeffizienten von Gesteinskörnungen

Diese Europäische Norm legt das Referenzverfahren fest, das für die Erstprüfung und im Streitfall für die Bestimmung des Fließkoeffizienten von groben und feinen Gesteinskörnungen angewendet wird. Für andere Zwecke, speziell im Rahmen der werkseigenen Produktionskontrolle, dürfen andere Verfahren angewendet werden, sofern ein ausreichender Zusammenhang mit dem Referenzverfahren nachgewiesen wurde. Beispiele für andere Prüfverfahren können in den Literaturhinweisen gefunden werden.
Die vorliegende Europäische Norm gilt für grobe Gesteinskörnungen mit Korngrößen zwischen 4 mm und 20 mm und feine Gesteinskörnungen mit Korngrößen bis zu 2 mm.
ANMERKUNG 1 Bei groben Gesteinskörnungen zwischen 4 mm und 20 mm hängt der Fließkoeffizient mit dem Prozent-satz an gebrochenen Körnern einer Gesteinskörnung zusammen und kann deshalb als alternatives Verfahren zu dem in EN 933-5 beschriebenen Verfahren angewendet werden. Das Ergebnis wird auch durch die Form und die Oberflächen-beschaffenheit beeinflusst.
ANMERKUNG 2 Erfahrungen mit diesem Prüfverfahren sind allgemein auf natürliche Gesteinskörnungen begrenzt.

Essais pour déterminer les caractéristiques géométriques des granulats - Partie 6: Evaluation des caractéristiques de surface - Coefficient d'écoulement des granulats

La présente Norme européenne décrit la méthode de référence servant aux essais de type initiaux et, en cas de litige, pour la détermination du coefficient d’écoulement des gravillons et des sables. Pour les besoins du contrôle de la production en usine en particulier, d’autres méthodes peuvent être utilisées sous réserve qu’une corrélation appropriée avec la méthode de référence ait été établie. Des exemples de méthodes d’essais avancés se trouvent éventuellement dans la Bibliographie.
La présente Norme européenne s’applique aux gravillons de classe granulaire comprise entre 4 mm et 20 mm et des sables de classe granulaire inférieure ou égale à 2 mm.
NOTE 1   Pour les gravillons compris entre 4 mm et 20 mm, le coefficient d’écoulement est lié au pourcentage de surfaces cassées de granulat et peut donc être utilisé pour remplacer la méthode spécifiée dans l’EN 933-5. Les caractéristiques de forme et de texture de surface influent également sur le résultat.
NOTE 2   L'application de cette norme a généralement été limitée aux granulats naturels.

Preskusi geometričnih lastnosti agregatov - 6. del: Ocenjevanje značilnosti površine - Količnik sipkosti agregatov

Standard EN 933-6 določa referenčno metodo, ki se uporablja za tipsko preskušanje in v primeru spora za določevanje koeficienta pretoka grobih in finih agregatov. Za druge namene, zlasti za nadzor proizvodnje v obratu, se lahko uporabijo druge metode, če obstaja primerna delovna povezava z referenčno metodo. Primeri naprednih preskusnih metod so opisani v bibliografiji. Ta evropski standard se uporablja za grobe agregate v velikosti od 4 mm do 20 mm in za fine agregate v velikosti do 2 mm.
