EVS-EN 50598-1:2015

This part of EN 50598 provides the general requirements to energy efficiency standardization for any extended product by using the guidance of the extended product approach (EPA).
It enables product committees for driven equipment with embedded motor systems (so called extended products) to interface with the relative power losses of the embedded motor system (e.g. PDS) in order to calculate the system energy efficiency for the whole application.
This shall be based on specified calculation models for speed/load profiles, the duty profiles and relative power losses of appropriate torque versus speed operating points.
This part of EN 50598 specifies the methodology of determination of losses of the extended product and its sub-parts.
This part of EN 50598 does not specify requirements for environmental impact declarations.
