Characterization of waste - Leaching behaviour test - Influence of pH on leaching with continuous pH control
This European Standard specifies a method for the determination of the influence of pH on the leachability of inorganic constituents from a waste material. Approaching equilibrium as defined in this European Standard is established by continuous adjustment of the pH by addition of acid or base to reach desired pH values. This test method produces eluates, which are subsequently characterized physically and chemically.
This European Standard is a parameter specific test as specified in EN 12920. The application of this test method alone is not sufficient for the determination of the detailed leaching behaviour of a waste under specified conditions.
Charakterisierung von Abfällen - Untersuchung des Elutionsverhaltens - Einfluss des pH-Wertes auf die Elution bei kontinuierlicher pH-Wert-Kontrolle
Diese Europäische Norm legt ein Verfahren für die Bestimmung des Einflusses des pH Wertes auf die Eluierbarkeit von anorganischen Bestandteilen aus Abfall fest. Die Annäherung an das Gleichgewicht, wie es in dieser Europäischen Norm definiert ist, wird durch kontinuierliche Einstellung des pH-Wertes durch Zugabe von Säure oder Base hergestellt, um die gewünschten endgültigen pH Werte zu erreichen. Dieses Prüfverfahren führt zu Eluaten, die anschließend physikalisch und chemisch charakterisiert werden.
Diese Europäische Norm ist eine parameterspezifische Prüfung, wie in EN 12920 festgelegt. Die Anwendung nur dieses Prüfverfahrens ist für die Bestimmung des genauen Elutionsverhaltens eines Abfalls unter festgelegten Bedingungen nicht ausreichend.
Caractérisation des déchets - Essais de comportement à la lixiviation - Influence du pH sur la lixiviation avec contrôle continu du pH
La présente Norme européenne définit une méthode de détermination de l’influence du pH sur la lixiviabilité des constituants inorganiques d’un déchet. L’approche de l'état d’équilibre tel que défini dans la présente Norme européenne s’obtient par un ajustement permanent du pH en ajoutant un acide ou une base pour atteindre les valeurs de pH souhaitées. Cette méthode d’essai produit des éluats qui sont ensuite caractérisés du point de vue physicochimique.
La présente Norme européenne est un essai paramétrique, tel que spécifié dans l'EN 12920. Cette méthode d’essai n’est pas suffisante, à elle seule, pour déterminer en détail le comportement à la lixiviation d’un déchet dans des conditions spécifiées.
