This European Standard specifies a method for the determination of pH within the range pH 2 to pH 12 in a suspension of sludge, treated biowaste or soil in either water (pH H2O), or a 0,01 mol/l calcium chloride solution (pH CaCl2).This European Standard is applicable to sludge, treated biowaste and fresh or air-dry soil samples.
