547/2012 - Commission Regulation (EU) No 547/2012 of 25 June 2012 implementing Directive 2009/125/EC of the European Parliament and of the Council with regard to ecodesign requirements for water pumps

This European standard specifies methods and procedures for testing, calculating and determining the Energy Efficiency Index (EEI) of rotodynamic glanded single pump units for pumping clean water, including where integrated in other products.
The pump types and sizes covered by this standard are described in the normative Annex A.

This document covers pump units consisting of:
-   one single or several rotodynamic water pump(s), including where integrated in other products, and driven by a motor system, consisting of an electrical motor and
-   either a terminal box which only enables to operate the pump unit at constant motor stator frequency and thereby (nearly) constant rotational speed,
-   or a CDM (Complete Drive Module) which enables to operate the pump unit at variable rotational speed depending on a varying demand of flow rate and/or discharge or differential pressure.
NOTE 1   A motor system which consists of an electric motor and a CDM is also called PDS (Power Drive System).
NOTE 2   A CDM is also often called VSD (Variable Speed Drive).
Pump units as defined above are treated as extended products in respect to their energy efficiency.

This document describes a methodology to evaluate energy efficiency performance of pump units based on a non-dimensional numerical value called Energy Efficiency Index (EEI).

This European Standard specifies performance requirements (methods and procedures for testing and calculating) for determining the Minimum Efficiency Index (MEI) of rotodynamic glanded water pumps for pumping clean water, including where integrated in other products.
The pump types and sizes covered by this standard are described in the Annex A. These pumps are designed and produced as duty pumps for pressures up to 16 bar for end suction pumps and up to 25 bar for multistage pumps, temperatures between -10 °C and +120 °C and 4" or 6" size for submersible multistage pumps at operating temperatures within a range of 0 °C and 90 °C.
In addition, this standard specifies how the value of the Minimum Efficiency Index (MEI) of a pump size indicated by the manufacturer can be checked by market surveillance.
Even if it is left free to the manufacturer of a pump size how to prove the rated value of the Minimum Efficiency Index (MEI), nevertheless this standard specifies a method to prove that this rated value meets the requirements within the confidence intervals with a sufficiently high probability.

This European Standard specifies requirements for flat modular tiles of natural stone which are made for internal (including enclosed public transport premises) and/or external uses as floorings, stairs and wall and ceiling finishes. This European Standard does not cover mineral aggregates and artificial agglomerated stone material and does not cover installation.

The pump types and sizes covered by this document are described in the Annex A. These pumps are designed and produced as duty pumps for pressures up to 16 bar for end suction pumps and up to 25 bar for multistage pumps, for all pumps designed for fluid temperatures between −10 °C and +120°C. Also covered are 4" (10,16 cm) and 6" (15,24 cm) submersible multistage pumps designed for fluid temperatures between 0 °C and 90 °C.
