Frequently Asked Questions

A European Standardization Mandate is a formal request from the European Commission to the European Standardization Organizations (CEN, CENELEC, and ETSI) to develop European standards (ENs) in support of EU legislation and policies. Mandates are issued under Regulation (EU) No 1025/2012 and help ensure that products and services meet the essential requirements set out in EU directives and regulations.

M/500 is a European Standardization Mandate titled "Mandate to CEN, CENELEC and ETSI for standardisation in the field of fans driven by motors with an electric input power between 125 W and 500 kW". Mandate to CEN, CENELEC and ETSI for standardisation in the field of fans driven by motors with an electric input power between 125 W and 500 kW There are 4 standards developed under this mandate.

Standards developed in response to a mandate and cited in the Official Journal of the European Union become "harmonized standards". Products manufactured in compliance with harmonized standards benefit from a presumption of conformity with the essential requirements of the corresponding EU directive or regulation, facilitating CE marking and market access across the European Economic Area.

Fans - Procedures and methods to determine the energy efficiency for the electrical input power range of 125 W up to 500 kW
oSIST prEN 17166:2024

This document provides procedures and methods for measuring and/or calculating the energy efficiency and associated characteristics of fans when driven by electric motors. This document deals with the following fan types;
-   axial fan;
-   centrifugal forward curved fan, centrifugal radial bladed fan;
-   centrifugal backward curved fan without housing, including centrifugal backward aerofoil fans;
-   centrifugal backward curved fan with housing, including centrifugal backward aerofoil fans;
-   mixed flow fan;
-   cross flow fan;
-   jet fan.
It provides procedures and methods to evaluate the compliance of the fan efficiency against minimum efficiency requirements.
This document includes stand-alone fans and fans that are integrated in other products. It gives guidance to manufacturers in providing information to surveillance authorities to describe the full extent of the fan by describing boundaries, significant elements and additional parts.
Some units previously identified as fans are now defined as Uni-Directional Ventilation Units. This document explains and shows by way of examples the difference between fans and Uni-Directional Ventilation Units.
This standard does not include:
-   Uni-Directional Ventilation Units;
-   fans that are designed specifically to operate in toxic, highly corrosive or flammable environments or in environments with abrasive substances, see Annex C.
