Tests for geometrical properties of aggregates - Part 3: Determination of particle shape - Flakiness index
This European Standard describes the reference method, used for type testing and in case of dispute, for determination of the flakiness index of aggregates. For other purposes, in particular production control, other methods may be used, provided that an appropriate working relationship with the reference method has been established.
This European Standard applies to natural, manufactured or recycled aggregates.
The test procedure specified in this part of this European Standard is not applicable to particle sizes less
Prüfverfahren für geometrische Eigenschaften von Gesteinskörnungen - Teil 3: Bestimmung der Kornform - Plattigkeitskennzahl
Diese Europäische Norm beschreibt das Referenzverfahren, das für die Typprüfung und im Streitfall für die
Bestimmung der Plattigkeitskennzahl von 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.
Diese Europäische Norm gilt für Gesteinskörnungen, die natürlicher, künstlicher (industrieller) Herkunft oder
aus recyclierten Stoffen hergestellt sind.
Das in diesem Teil der Europäischen Norm festgelegte Verfahren gilt nicht für Korngrößen < 4 mm oder
> 100 mm.
Essais pour déterminer les caractéristiques géométriques des granulats - Partie 3: Détermination de la forme des granulats - Coefficient d'aplatissement
La présente Norme européenne décrit la méthode de référence servant aux essais de type initiaux et, en cas de désaccord, à la détermination du coefficient d’aplatissement des granulats. Pour les besoins du contrôle de la production en particulier, d’autres méthodes peuvent être utilisées sous réserve qu’une corrélation appropriée avec la méthode de référence ait été établie.
La présente Norme européenne s’applique à des agrégats naturels, artificiels ou recyclés.
Le mode opératoire de l'essai indiqué dans cette partie de la norme européenne ne s'applique pas aux particules de dimension inférieure à 4 mm ou supérieure à 100 mm.
Preskusi geometričnih lastnosti agregatov - 3. del: Določevanje oblike zrn - Modul ploščatosti
Ta evropski standard opisuje referenčno metodo, ki se uporablja za tipsko preskušanje in v primeru spora za določevanje modula ploščatosti agregatov. Za druge namene, zlasti za kontrolo proizvodnje, se lahko uporabijo druge metode, če obstaja primerna delovna povezava z referenčno metodo. Ta evropski standard se uporablja za naravne, umetne ali reciklirane agregate. Preskusni postopek iz tega dela tega evropskega standarda se ne uporablja za zrna, manjša od 4 mm ali večja od 100 mm.
