4 Assessment methods and criteria
4.1 Characteristic curves, minimum flow and rotational speed tests
4.1.1 Assessment method
Pump characteristic curves shall be drawn for the rated speed condition. The highest flow to be shown in
the curves shall be sufficient to demonstrate a non-overloading power characteristic or a flow
corresponding to at least NPSHr of 16 m.
In case of non-overloading power characteristic, all curves shall be shown including values which are
minimum 15 % higher than the flow at the maximum power demand.
The flow, power consumption, NPSHr and the corresponding delivery head shall be determined in
accordance with EN ISO 9906:2012, Grade 2. The measurement uncertainty as specified in
EN ISO 9906:2012, Grade 2 shall be applied.
NOTE For examples, see Annex A.
Type tests and conversion of test data shall be undertaken using methods defined in EN ISO 9906:2012,
Grade 2 and the tolerances given there.
Where there are a range of impeller diameters, tests shall include the maxi
