Tests for chemical properties of aggregates - Part 3: Preparation of eluates by leaching of aggregates
This European standard specifies a method for the preparation of eluates, by leaching of aggregates, for subsequent investigation of physical and chemical properties by existing standard methods for the purpose of compliance testing. It applies to unbound aggregates that have a particle size below 32 mm with or without size reduction (see clause 8).
Prüfverfahren für chemische Eigenschaften von Gesteinskörnungen - Teil 3: Herstellung von Eluaten durch Auslaugung von Gesteinskörnungen
Diese Europäische Norm legt ein Verfahren für die Herstellung von Eluaten durch Auslaugung von Gesteinskörnungen für die nachfolgende Untersuchung der physikalischen und chemischen Eigenschaften mittels vorhandener genormter Verfahren zur Prüfung der Konformität fest. Sie gilt für ungebundene Gesteinskörnungen, die eine Korngröße unter 32 mm mit oder ohne Korngrößenreduzierung haben (siehe Abschnitt 8).
Essais pour déterminer les propriétés chimiques des granulats - Partie 3: Préparation d'éluats par lixiviation des granulats
La présente norme européenne spécifie une méthode de préparation d'éluats par lixiviation de granulats en vue de l'étude ultérieure des propriétés physiques et chimiques selon des méthodes normalisées existantes. Elle s'applique aux graves de granularité inférieure à 32 mm, avec ou sans réduction (voir article 8).
