Fans - Efficiency classification for fans (ISO 12759:2010, including Amd 1:2013)
ISO 12759:2010 specifies requirements for classification of fan efficiency for all fan types driven by motors with an electrical input power range from 0,125 kW to 500 kW. It is applicable to (bare shaft and driven) fans, as well as fans integrated into products. Fans integrated into products are measured as stand-alone fans.
It is not applicable to fans for smoke and emergency smoke extraction; fans for industrial processes; fans for automotive application, trains, planes, etc.; fans for potentially explosive atmospheres; box fans, powered roof ventilators and air curtains or jet fans for use in car parks and tunnel ventilation.

Ventilateurs - Classification du rendement des ventilateurs (ISO 12759:2010, y compris Amd 1:2013)
L'ISO 12759:2010 établit une classification du rendement de tous les types de ventilateurs entraînés par des moteurs dont la puissance électrique absorbée est comprise entre 0,125 kW et 500 kW. Elle est applicable aux ventilateurs à arbre nu et à entraînement, ainsi qu'aux ventilateurs intégrés à des produits. Ces derniers sont mesurés en tant que ventilateurs autonomes.
Elle n'est pas applicable aux ventilateurs utilisés pour l'extraction des fumées et le désenfumage; aux ventilateurs pour les procédés industriels; aux ventilateurs pour les applications automobiles, les trains, les avions, etc.; aux ventilateurs placés en atmosphères potentiellement explosives; aux ventilateurs en caisson, aux tourelles d'extraction motorisées, aux rideaux d'air; ni aux ventilateurs utilisés dans les parkings et pour la ventilation des tunnels.
Ventilatorji - Klasifikacija učinkovitosti za ventilatorje (ISO 12759:2010, vključuje dopolnilo A1:2013)
Ta mednarodni standard določa klasifikacijo učinkovitosti za ventilatorje za vse vrste ventilatorjev z motorji z razponom električne vhodne moči od 0,125 kW do 500 kW. Ta mednarodni standard se uporablja za ventilatorje z golo gredjo in pogonom ter ventilatorje, vgrajene v izdelke. Ventilatorji, vgrajeni v izdelke, se merijo kot samostojni ventilatorji.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 12759 was prepared by Technical Committee ISO/TC 117, Fans.

Introduction
The last decade has seen not only an escalation in the price, but also an increasing recognition of the finite life
of many of the fossil fuels in use. There is also a belief that climatic change is due to an increase in the levels
of carbon dioxide in the atmosphere. This has lead to many nations reviewing methods of energy generation
and usage.
Therefore, there is a need to promote energy efficiency in order to maintain economic growth. This requires
better selection of equipment by users and better design of this equipment by manufacturers.
Fans of all types are used for ventilation and air conditioning, process engineering (drying, pneumatic
conveying), combustion air supply and agriculture, etc. Indeed, the energy usage by fans has been calculated
as nearly 20 % of worldwide demand.
The fan industry is of a global nature, with a considerable degree of exporting and licensing. To ensure that
defined fan performance characteristics are common throughout the world, a series of International Standards
has been developed. It is the belief of the industry that there is a need for the recognition of minimum
efficiency standards. To encourage their implementation, a classification system is proposed which
incorporates a series of efficiency bands. With improvements in technology and manufacturing processes, the
minimum efficiency levels can be reviewed and increased over time.
This International Standard can be used by legislators or regulatory bodies for defining future energy saving
targets.
