What is BS 1647-2- Reference value standard solutions and operational reference standard solutions about?
BS 1647 discusses pH measurement. BS 1647-2 is the second part of the BS 1647 multi-series and discusses specifications for reference value standard solutions and operational reference standard solutions.
Operational pH standards are those assigned pH values at various temperatures based on the operational cell measurements specified in BS 1647-2. Where the operational reference standard is solution X and the reference value standard is solution S.
Who is BS 1647-2 - Reference value standard solutions and operational reference standard solutions for?
BS 1647-2 on specifications for reference value standard solutions and operational reference standard solutions is useful for:
- Chemical manufactures
- Chemical engineers
- Scientists
- Inspection personnel
Why should you use BS 1647-2- Reference value standard solutions and operational reference standard solutions?
As specified in BS 1647-1, the reference value standard solution is an aqueous solution of potassium hydrogen phthalate with a molality of 0.5 mol/kg. BS 1647-2 provides you with the preparation of the reference value standard solution used as the basis of the pH scale specified in BS 1647-1.
BS 1647-2 provides you with the requirements for operational reference standard solutions suitable for calibration of pH meters against this pH scale. BS 1647-2 also provides you with the accuracy classes for pH measurements.
