Solid biofuels - Determination of minor elements - As, Cd, Co, Cr, Cu, Hg, Mn, Mo, Ni, Pb, Sb, V and Zn; German version EN 15297:2011
Feste Biobrennstoffe - Bestimmung von Spurenelementen - As, Cd, Co, Cr, Cu, Hg, Mn, Mo, Ni, Pb, Sb, V und Zn; Deutsche Fassung EN 15297:2011
Overview
This European Standard is intended for determination of the minor elements arsenic, cadmium, cobalt, chromium, copper, mercury, manganese, molybdenum, nickel, lead, antimony, vanadium and zinc in all solid biofuels. Further it describes methods for sample decomposition and suggests suitable instrumental methods for the determination of the elements of interest in the digests. The determination of other elements as selenium, tin and thallium is also possible with the method described in this European Standard. The analysis sample is digested in a closed vessel made from a fluoropolymer using nitric acid, hydrogen peroxide and hydrofluoric acid in a microwave oven or a resistance oven or heating block. The digest is then diluted and the elements determined with suitable instruments. This document has been prepared by Technical Committee CEN/TC 335 "Solid biofuels", the secretariat of which is held by SIS (Sweden). The responsible German committee is Working Committee NA 062-05-82 AA "Feste Biobrennstoffe" ("Solid biofuels") at NMP.
