DIN EN 14582:2016-12

Sulfur and halogens (fluorine, chlorine, bromine and iodine) may be found in materials in various forms. During the combustion of these materials, corrosive and harmful compounds may be released. The determination of sulfur and halogens by oxygen combustion may be used to assess the suitability of waste for incineration. The determination of the resultant halides and sulphate can be achieved by many different techniques, such as by using atomic emission spectrometry, titrimetry or ion chromatography. This European Standard specifies a combustion method for the determination of halogen and sulfur contents in materials by combustion in a closed system containing oxygen (calorimetric bomb), and the subsequent analysis of the combustion product using different analytical techniques. This method is applicable to solid, pasty and liquid samples containing more than 0,025 g/kg of halogen and/or 0,025 g/kg of sulfur content. The limit of detection depends on the element, the matrix and the determination technique used. Insoluble halides and sulphate present in the sample or produced during the combustion step are not completely determined by these methods. The subcommittee responsible for this standard is NA 119-01-02-02 UA "Chemische und physikalische Verfahren" ("Chemical and physical methods") of Working Committee NA 119-01-02 AA "Abfall- und Bodenuntersuchung" ("Waste and soil investigation") at DIN Standards Committee Water Practice (NAW).
