Tests for geometrical properties of aggregates - Part 4: Determination of particle shape - Shape index

This standard describes the reference method used for type testing in cases of dispute, for the determination of the shape index of coarse aggregates. For other purposes, in particular factory production control, other methods may be used provided an appropriate working relationship with the reference method has been established.
The test method specified in this European Standard is applicable to particle size fractions di/Di where Di ≤ 63 mm and di ≥ 4 mm.

Prüfverfahren für geometrische Eigenschaften von Gesteinskörnungen - Teil 4: Bestimmung der Kornform - Kornformkennzahl

Diese Norm beschreibt das Referenzverfahren für die Erstprüfung und in Streitfällen für die Bestimmung der Kornformkennzahl von groben Gesteinskörnungen. Für andere Zwecke, speziell im Rahmen der werkseigenen Produktionskontrolle, dürfen andere Verfahren angewendet werden, sofern ein ausreichender Zusammenhang mit dem Referenzverfahren nachgewiesen wurde.
Das in dieser Europäischen Norm festgelegte Prüfverfahren ist für Kornklassen di/Di mit Di  63 mm und di  4 mm anwendbar.

Essais pour déterminer les caractéristiques géométriques des granulats - Partie 4: Détermination de la forme des granulats - Indice de forme

La présente norme décrit la méthode de référence utilisée pour les essais de type et, en cas de conflit, pour la détermination de l’indice de forme des gravillons. Pour d'autres objectifs, en particulier dans le cadre du contrôle de la production en usine, d'autres méthodes peuvent être employées si une corrélation appropriée avec la méthode de référence a été établie.
La méthode d'essai spécifiée dans la présente Norme européenne s'applique à la fraction granulaire di/Di où Di = 63 mm et di = 4 mm.
