Scope
This document specifies an instrumental method for the routine determination of pH within the range pH 2 to pH 12 using a glass electrode in a 1:5 (volume fraction) suspension of soil, sludge and treated biowaste in either water (pH in H2O), in 1 mol/l potassium chloride solution (pH in KCl) or in 0,01 mol/l calcium chloride solution (pH in CaCl2).
This document is applicable to all types of air-dried soil and treated biowaste samples.
NOTE For example, pretreated in accordance with PS 3055 or EN 16179 or EN 15002.
