Endised kalkuse ühikud 0d ja mval/l on asendatud leelismuldmetallide sisalduse ühikutega mmol/l, mol/m3 ja mg/l seosest 1 mmol/l = 1 mol/m3, mis vastab 2 mval/l, andes 56 mg CaO/l.
The former units for hardness 0d and mval/l have been replaced by units for the sum of alkaline earth mmol/l, mol/m3 and mg/l (1 mmol/l = 1 mol/m3 corresponding to 2 mval/l that will give 56 mg CaO/l).
