BS EN 14582:2016 pdf free.Characterization of waste Halogen and sulfur content – Oxygen combustion in closed systems and determination methods.
BS EN 14582 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.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
NOTE He aware that the above definitions are valid for this empirical EN only and do not comply with scientific definitions of sulfur and halogen content.
3.1 sulfur content
sum of sulfur contained as organic and inorganic compounds that can be converted to sulphate by combustion and then absorbed or dissolved in an aqueous solution
3.2 halogen content
sum of halogens contained as organic and inorganic compounds that can be converted to halides (fluoride, chloride, bromide, iodide) by combustion and then absorbed or dissolved in an aqueous solution
4 Principle
The sample is oxidized by combustion in a closed system (a bomb containing oxygen under pressure). Halogenated and sulfur containing compounds are converted to fluoride, chloride, bromide, iodide and sulphate, which are absorbed and/or dissolved in an absorption solution.BS EN 14582 pdf free download.
