Water quality - Performance requirements and conformity test procedures for water monitoring equipment - Part 2: Continuous measurement devices cen:proj:58752

Scope

This standard specifies general requirements and performance test procedures for continuous measuring devices (CMDs) that are normally fixed in position and used to measure physical and chemical determinands in water. The general requirements include functional facilities that CMDs must have to meet users‘ applications and information that has to be included in associated documents. The test procedures specify uniform methods to be used when determining key performance characteristics of CMDs. The performance tests comprise testing carried out under laboratory and field conditions Statistical procedures are defined for evaluation of the test data. It is recognised that for some devices certain test procedures are not applicable. Expected values for performance characteristics for a range of CMDs are detailed in Annex A for guidance.
