Sammendrag
Eleven laboratories in ten countries participated in intercalibration 9004, especially designed for testing of pH and alkalinity determination. The estimate of a total error of +/- 0.2 pH units seems to be a reasonable assessment of the accuracy of routine determination of pH. Measurement without stirring the solution is recommended. Regarding the determination of alkalinity, the Gran plot titration method is strongly recommended.
