This European standard specifies general requirements, minimum performance requirements and test procedures forinstrumentation used to measure either volumetric flow-rate and/or total volume passed of water in closed conduits. It covers all closed conduit instrument (CCI) technologies intended to operate in closed pressurised pipes and partially filled pipes. It is recognised that for some CCIs certain tests cannot be carried out. The data obtained from the testing of CCIs in accordance with the requirements of the Measuring Instruments Directive [4] or ISO4064-1 [5] can be used to meet, in part, the requirements specified in this European Standard. However, for the avoidance of doubt,compliance with the requirements of this European Standard does not equate to compliance with the requirements of theMeasuring Instruments Directive or ISO 4064-1.
