is the dry residue of the sample, expressed as mass fraction in per cent [%] or in grams per kilogram [g/kg]; ma
is the mass of the empty dish or crucible, expressed in grams [g];

is the mass of the dish or crucible containing the sample, expressed in grams [g]; mc
is the mass of the dish or crucible containing the dried sample, expressed in grams [g]; f is the conversion factor f = 100 for expression of results as mass fraction in per cent [%] and f = 1 000 for expression of results in grams per kilogram [g/kg]. The analysis is performed at least in duplicate; the mean value is calculated and reported. 7 Method B — Direct Karl-Fischer-titration (volumetric/coulometric detection) 7.1 Interferences Substances like peroxides, oxides, hydroxides, ammonia, carbonates, hydrogen carbonates, disulfites, nitrite, sulfite, thiosulfate, hydrazine and derivatives, iron (II), copper (I), tin (II), silanoles, arsenite, arsenate, selenite, tellurite, phenols, boric compounds, aldehydes, acetone and other reactive ketones may interfere. Especially all reductive or oxidative reagents are potentially interfering. In case of concern about interferences results can be verified by azeotropic distillation (Annex B). Most of the interferences are reduced in case of extraction with methanol before analysis. 7.2 Reagents All reagents used shall be at least an
