If
the pump pressure drops by more than 5% as indicated in the original acceptance
test characteristics curves where no calibration is applied, or as indicated in
the nameplate, the cause of the performance decrease should be investigated.

Where
amperage and voltage readings do not exceed the product of rated voltage and
rated full-load amperage multiplied by the rated motor service factor, such
performance is deemed acceptable. Motor voltage reading 5%
below or 10% above rated voltage (marked on the nameplate), as a maximum, will
be deemed acceptable.
