Tests for chemical properties of aggregates - Part 8: Sorting test to determine metal content of Municipal Incinerator Bottom Ash (MIBA) Aggregates; German version EN 1744-8:2012
Prüfverfahren für chemische Eigenschaften von Gesteinskörnungen - Teil 8: Sortierverfahren zur Bestimmung des Metallgehalts in Hausmüllverbrennungsasche (HMV-Asche); Deutsche Fassung EN 1744-8:2012
Overview
This European Standard specifies a simple method for the examination of Municipal Incinerator Bottom Ash (MIBA) Aggregates for the purpose of estimating the relative proportions of metallic constituents. This European Standard describes the reference methods used for type testing and, in case of dispute, for estimating the relative proportions of aluminium or other metallic constituents of MIBA Aggregates. For other purposes, in particular factory production control, other methods may be used provided that an appropriate working relationship with the reference method has been established. The test consists of sorting particles from a subsample of the coarse part of MIBA Aggregates by hand to separate out metallic particles. The metallic particles are then separated into ferrous (magnetic) and non-ferrous (non-magnetic) particles using a magnet. The proportion by mass of each of these constituents is determined and expressed as a percentage of the mass of the subsample. This document (prEN 16262:2011) has been prepared by Technical Committee CEN/TC 154 "Aggregates", the secretariat of which is held by BSI (United Kingdom). The responsible national committee is Working Committee NA 062-03-13 AA "Gesteinskörnungen; Prüfverfahren, Petrographie, Probenahme und Präzision" ("Aggregates; test methods, petrography, sampling and precision") at the Materials Testing Standards Committee (NMP) of DIN.
