ISO 13347-4:2004
2004-08
Abstract
ISO 13347-4:2004 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.
The sizes of the fan, which can be tested in accordance with ISO 13347-4:2004, are limited only by the practical aspects of the test installations.
ISO 13347-4:2004 determines sound power by using sound intensity measurements on a measurement surface which encloses the sound source. It provides guidelines on the acoustical environment, ambient noise, measurement surface, and number of measurements. The test set-ups are generally designed to represent the physical orientation of a fan installed in accordance with ISO 5801 and also used in ISO 13347-2.
