Characterization of waste - Leaching behaviour test - Influence of pH on leaching with continuous pH control; German version EN 14997:2015
Charakterisierung von Abfällen - Untersuchung des Elutionsverhaltens - Einfluss des pH-Wertes auf die Elution bei kontinuierlicher pH-Wert-Kontrolle; Deutsche Fassung EN 14997:2015
Overview
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 document has been prepared by Technical Committee CEN/TC 292 "Characterization of waste", the secretariat of which is held by NEN (Netherlands). The responsible German body is NA 119-01-02-05 UA "Elutionsverfahren" ("Leaching methods") of Working Committee NA 119-01-02 AA "Abfall- und Bodenuntersuchung" ("Waste and soil investigation") of the DIN Standards Committee Water Practice (NAW).
