EVS-EN ISO 14414:2015

The purpose of this standard is to prepare methodologies for the evaluation of the efficiency of pump systems. The pump systems of immediate interest are those in Buildings, Water Utilities and Chemical processes.
This International Standard deals with evaluation of systems where a significant component of the energy consumed is by pumps on water applications (centrifugal, mixed flow and axial pumps). It may be applied to pumps of any size and to any pumped liquids that behave as clean cold water.
This standard may also be used with care with systems with pumps for sludges, slurries or viscous liquids or those with suspended solids where special design rotodynamic and positive displacement pumps are used.
