DIN CEN/TS 16172:2013-04

This Technical Specification specifies a method for the determination of trace elements in aqua regia or nitric acid digest solutions of sludge, treated biowaste and soil, using atomic absorption spectrometry with electrothermal atomisation in a graphite furnace. The method is applicable for the determination of the following elements: antimony (Sb), arsenic (As), cadmium (Cd), cobalt (Co), lead (Pb), thallium (Tl), vanadium (V). DIN CEN/TS 16172:2013 (DIN SPEC 91258) has been prepared by Technical Committee CEN/TC 400 "Project Committee - Horizontal Standards in the fields of sludge, biowaste and soil", the secretariat of which is held by DIN. The responsible German committee is NA 119-01-02-02 UA "Chemische und physikalische Verfahren" ("Chemical and physical processes") of NA 119-01-02 AA "Abfall- und Bodenuntersuchung" ("Examination of waste and soil") at the Water Practice Standards Committee (NAW) at DIN. The preparation of this document by CEN is based on a mandate by the European Commission (Mandate M/330) comprising standards on sampling and analytical methods for hygienic and biological parameters as well as inorganic and organic determinants with the aim to prepare these standards to make these standards applicable to sludge, treated biowaste and soil as far as this is technically feasible. This document CEN/TS 16172 (DIN SPEC 91258) is the result of a standardization project which has not been published as a standard by CEN/TC 400 due to certain provisos to the content or due to the preparation procedure deviating from a European Standard. Technical Specifications of CEN have the status of a prestandard and are therefore published by DIN as DIN SPEC with an individual number. This CEN/TS 16172 (DIN SPEC 91258) has been published as draft under E DIN EN 16172:2011-01.
