Operational standard reference materials and preparation of reference value reference solution and operational standard reference solutions

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.

NOTE The titles of the publications referred to in this Part of this standard are listed on the inside back cover.
