This standard specifies six methods for determination of acid and base capacity in water. It describes the methods for determination of acid capacity to pH 8,2 and pH 4,3 and base capacity to pH 4,3 and pH 8,2 by titration with and without addition of masking agent tartrate citrate solution as well as by back titration.
