This Part of BS 1647 specifies the preparation of the reference value standard solution used as the basis of the pH scale specified in Part 1 of this standard and requirements for operational reference standard solutions suitable for calibration of pH meters against this pH scale. It also specifies accuracy classes for pH measurements.
