Water quality - Performance requirements and conformity test procedures for water monitoring equipment - Part 3: Portable measurement devices cen:proj:58751

Scope

This standard specifies general requirements and performance test procedures for portable measuring devices (PMDs) used to measure physical and chemical determinands in water. The general requirements include functional facilities that PMDs 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 PMDs. 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 PMDs are detailed in Annex A for guidance.
