Overview

EN 60746-2:2003 (CLC) - "Expression of performance of electrochemical analyzers - Part 2: pH value" defines how the performance of electrochemical pH analyzers is to be expressed and reported. This consolidated copy includes the corrigenda published in May and July 2003. Classified under ICS 71.040.40 (Chemical analysis), the standard supports consistent communication of instrument capability between manufacturers, laboratories and users.

Key topics

The standard focuses on the clear, repeatable expression of pH analyzer performance. Typical, non‑numeric topics covered include:

  • Performance parameters and terminology - definitions of measurable characteristics relevant to pH measurement (for example: accuracy, precision, repeatability, reproducibility).
  • Measurement uncertainty and expression of results - guidance on how to present uncertainty and the confidence in reported pH values.
  • Calibration and traceability - requirements for describing calibration procedures and traceability to reference standards.
  • Response characteristics - how to report response time, drift and stability in pH measurements.
  • Environmental and operational conditions - statement of conditions (temperature, sample matrix, ionic strength) under which stated performance applies.
  • Test and reporting formats - standardized ways to present performance data in datasheets, manuals and certificates.
  • Documentation and labeling - what performance information should accompany instruments for proper interpretation by users.

Note: this summary describes the scope and common subject matter of Part 2 (pH). It does not give procedural details or numerical limits, which are specified in the full standard text.

Applications

EN 60746-2:2003 is practical for anyone involved with pH measurement systems who needs clear, comparable performance information:

  • Instrument manufacturers - to prepare compliant datasheets, user manuals and performance claims.
  • Test and calibration laboratories - to report measurement uncertainty and verify instrument performance.
  • Water, wastewater, environmental and process control engineers - to select instruments that meet operational requirements.
  • Procurement and quality managers - to evaluate vendor claims and ensure specifications match application needs.
  • Regulators and accreditation bodies - to harmonize reporting and ensure consistent interpretation of pH data.

Related standards

  • General series EN 60746 (other parts) addressing expression of performance for other electrochemical analytes.
  • ISO/IEC and national electrochemical measurement standards relating to calibration and uncertainty reporting.

Using EN 60746-2:2003 helps ensure pH meter performance is expressed in a standardized, transparent way - improving comparability, traceability and confidence in pH measurement results.
