This Technical Report concerns analyzers, sensor units and electronic units used for the
determination of pH in non-aqueous solvents and aqueous organic solvent mixtures using
glass electrodes. IEC 60746-1 includes further definition of the scope and provides for the
general aspects of all electrochemical analyzers, including pH. It is worthwhile to remind that
IEC 60746-2 contains specifications for simulators used for testing pH electronic units.
This technical report specifies the terminology, definitions, methodology, requirements for
statements by manufacturers and performance tests for analyzers, sensor units and electronic
units used for the determination of pH value in non-aqueous and aqueous-organic solvent
mixtures.
