FprEN 17170

Fans - Safety requirements

This document is applicable to all types of fans other than fans that are household appliances intended for household and similar purposes. The fan can be either a complete machine or a partly completed machine intended to be incorporated into/or assembled with other machinery or other partly completed machinery or equipment.
NOTE   Fans intended for household purposes are typically used on desks, ceilings, free standing or, partitions (e.g. window and wall fans) and ducts not listing here built in components for other household appliances. They are assumed to have mainly electricity related risks. These fans are in the scope of the EN 60335 series. Appliances not intended for normal household use but which nevertheless because of their similar use may be a source of danger to the public, such as appliances intended for use in shops, in light industry and on farms, are within the scope of the EN 60335 series of standards.
This document deals with all significant hazards, hazardous situations and events relevant to fans during transport, assembly and installation, commissioning and use as well as decommissioning as defined in EN ISO 12100:2010, Annex B, when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer.
This document  applies to electrically driven fans and, apart from the hazards related to the drives, it also applies to fans driven from other energy sources.
Further safety measures might be required for the additional hazards due to the application.
This document  does not deal with the hazards due to the use of fans in a potentially explosive atmosphere (see e.g. EN 14986).

This draft European Standard is submitted to CEN members for enquiry. It has been drawn up by the Technical Committee
CEN/TC 156.
If this draft becomes a European Standard, CEN members are bound to comply with the CEN/CENELEC Internal Regulations
which stipulate the conditions for giving this European Standard the status of a national standard without any alteration.

This draft European Standard was established by CEN in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC
Management Centre has the same status as the official versions.

for buildings”, the secretariat of which is held by BSI.
This document is currently submitted to the CEN Enquiry.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association, and supports essential requirements of EU Directive 2006/42/EC.

Introduction
This document is a type C standard as stated in EN ISO 12100:2010.
The machinery concerned and the extent to which hazards, hazardous situations and hazardous events
are covered are indicated in the scope of this document.
When provisions of this type C standard are different from those which are stated in type A or B
standards, the provisions of this type C standard take precedence over the provisions of the other
standards, for machines that have been designed and built according to the provisions of this type C
standard.
Where specific type C standards exist for particular applications of fans, the provisions of these type C
standards shall take precedence over the provisions of this standard.
In addition, machinery should comply as appropriate with EN ISO 12100:2010 for general machinery
hazards which are not covered by this standard.
prEN 17170:2017 (E)
1 Scope
This European Standard is applicable to all types of fans other than fans that are household appliances
intended for domestic use.
NOTE 1 Fans intended for household purposes are typically used on desks, ceilings, free standing or, partitions
(e.g. window and wall fans) and ducts. They are assumed to have mainly electricity related risks. These fans are in
the scope of EN 60335-2-80.
It deals with all significant hazards, hazardous situations and events relevant to fans during transport,
assembly and installation, commissioning and use as defined in EN ISO 12100:2010, Annex B, when they
are used as intended and under conditions of misuse which are reasonably foreseeable by the
manufacturer (see 3,24).
NOTE 2 This standard deals a.) with standalone fan units, ready for operation, complete with control systems
and all other features that ensure safety in use and b.) with fans for installation (e.g. in ventilation systems) or
incorporation with other equipment where control systems and all other features that ensure safety are provided
by others, (details should be provided by the fan manufacturer).
This European Standard applies to electrically driven fans and, apart from the hazards related to the
drives, it shall also apply to fans driven from other energy sources.
Further safety measures may be required for the additional hazards due to the application.
This European Standard does not deal with the hazards due to the use of fans in a potentially explosive
atmosphere (see e.g. EN ISO 14986).
This European Standard is not applicable to fans, which are manufactured before the date of its
publication.
