| ISO | 1973-11 | 3 |
Describes the measurement of a solution of a test sample by means of a pH meter fitted with one glass electrode and one calomel electrode. The pH meter has a sensitivity of 0.05 pH units. The calibration of the pH meter is carried out at (20 0.5) 0C by means of buffer solutions. The method has also been approved by the IUPAC.
