EN ISO 15839:2006 PDF

Overview

EN ISO 15839:2006 (ISO 15839:2003) specifies how to define, test and report the performance of on-line sensors and analysing equipment for water quality. Adopted by CEN from ISO, this standard establishes common terminology and test procedures for evaluating sensor/analysing equipment both in the laboratory and in the field. It is applicable to most types of on-line water quality sensors, while acknowledging that some specific tests may not be feasible for certain devices.

Key Topics

• Definitions and terminology for on-line sensors/analysing equipment and measurement/analytical chains (e.g., determinand, calibration solution, measurement chain).
• Performance characteristics that must be assessed, including:
  • Accuracy and bias
  • Precision, repeatability, and day-to-day repeatability
  • Limit of detection (LOD) and limit of quantification (LOQ)
  • Response time, delay time, fall time
  • Long-term drift, memory effect
  • Interference and interferents
  • Availability and period between maintenance operations
• Test procedures and protocols for:
  • Laboratory testing to determine instrument-specific characteristics under controlled conditions.
  • Field testing to evaluate performance within the complete measurement chain (sampling, pretreatment, transport, analyser).
• Informative annexes providing guidance on manufacturer information, measurement-chain diagrams, recommended test bench setups, test scheduling and example test reports.
• Normative references that support statistical and analytical quality practices (e.g., ISO 5725-1, ISO 8466-1, ISO/TR 13530).

Applications

EN ISO 15839 is used to:

• Validate and compare on-line water quality sensors before procurement or deployment.
• Support manufacturers in documenting and claiming performance characteristics.
• Guide testing laboratories in performing standardized laboratory and field performance tests.
• Help water utilities, environmental agencies and system integrators evaluate sensor suitability for continuous monitoring, early-warning systems and compliance monitoring.
• Provide a basis for tender specifications and acceptance testing of on-line analysers.

Who should use this standard

• Sensor and analyser manufacturers
• Independent test laboratories
• Water utilities, wastewater operators and environmental regulators
• R&D teams developing water quality monitoring solutions
• Procurement and QA engineers specifying on-line monitoring equipment
