BS PD ISO/TS 15923-2:2017

BS PD ISO/TS 15923-2:2017 specifies methods for the automatic determination of chromium(VI), fluoride, totalalkalinity, total hardness, calcium, magnesium, iron, iron(II), manganese and aluminium withphotometric determination using a discrete analysis system. The field of application is water (ground,potable, surface, waste, eluates and boiler water). The method can also be applied to marine waters withmatrix matching of standard and control solutions. Note that some parameters, notably iron, manganeseand aluminium and possibly chromium(VI), calcium and magnesium may not be completely quantifiedif the sample contains particulates. Samples can be digested in acid, as long as the buffering capacity ofthe reaction mixture is not exceeded. Such procedures are beyond the scope of this document, which isbest suited to the determination of dissolved metals following on-site filtration.Cross References:ISO 8466-2:2001ISO 8466-1:1990 (R10)ISO 3696:1987ISO 5667-3:2012 ED4ISO 23913:2006 Ed 1ISO 18412:2005 Ed 1
