EN 50216-12 deals with fans for oil-to-air coolers used for transformers as well as fans used for blowing out radiators. Only fans operating axially are dealt with in this standard specification. This standard specification defines the dimensions and requirements for ensuring...
This document applies to electrical fans (including their accessories and their component parts) for household and similar use, designed for AC or DC supply. The motor, the impeller and their housing, if any, form a single unit. These particular requirements apply to: - conventional...
This standard deals with the determination of the acoustic performance of industrial fans under laboratory conditions. In addition, it may be used to determine the acoustic performance of fans combined with an ancillary device such as a roof cowl or damper or, where the fan is...
This International Standard gives specifications for vibration and balance limits of fans for all applications except those designed solely for air circulation, for example, ceiling fans and table fans. However, it is limited to fans of all types installed with a power...
This European Standard specifies aerodynamic, acoustic and electrical power performance test methods for fans used in residential ventilation. These methods primarily concern: - ventilation fans installed on a wall or in a window without any duct; - ventilation fans installed...

IEC 60704-2-7:2020 is available as IEC 60704-2-7:2020 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition. IEC 60704-2-7:2020 applies...
This International Standard specifies a method for testing ducted fans and other air-moving devices to determine the sound power radiated into an anechoically terminated duct on the inlet and/or outlet side of the equipment. NOTE 1 For the sake of brevity, wherever the term "fan"...
Determination of the acoustic performance of fans operating against difference of pressure. Four methods are described: in-duct, reverberant field, free field and semi-reverberant. Illustrations are given of suitable test ducting and anechoic terminations.

This standard applies to electrical fans (including their accessories and their component parts), for household and similar use, designed for a.c. or d.c. supply.
This standard gives a detailed description of reveberant room methods for the determination of fan sound power levels. It is for use under standardized laboratory conditions and recognises that tests in situ are subject to increased uncertainty.
This standard applies to industrial fans as defined in ISO 5801 and ISO 13349. It is limited to the determination of airborne sound emission for the specified set-ups. Vibration is not measured, nor is the sensitivity of airborne sound emission to vibration effects determined.

5.1 All noise control features associated with the inlet or exhaust of large industrial fans and gas turbines are, or should be, based upon inlet or exhaust sound power levels in octave bands of frequency. Sound power levels are not directly measurable, however, so they must be calculated...
This document sets out guidelines for the specific procedures to be considered when carrying out vibration diagnostics of various types of fans and blowers. This document is intended to be used by condition monitoring practitioners, engineers and technicians and provides a practical...
