DESCRIPTION

BS 1647-2:1984


This standard BS 1647-2:1984 pH measurement is classified in these ICS categories:
  • 71.040.50 Physicochemical methods of analysis
  • 71.040.30 Chemical reagents

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.


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