ISO 13347-3:2004
2004-08
Abstract
ISO 13347-3:2004 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 fan which can be tested in accordance with ISO 13347-3:2004 are limited only by the practical aspects of the test set-up. Dimensional limitations, test fan dimensions, and air performance will control the room size, power and mounting requirements for the test fan.
The test arrangements in ISO 13347-3:2004 establish the laboratory conditions necessary for a successful test. Rarely will it be possible to meet these requirements in situ and ISO 13347-3:2004 is not intended for field measurements. Intending users are reminded that, in these situations, there may well be additional acoustic system effects where inlet and outlet conditions at the fan are less than ideal.
The enveloping surface methods may be used for the determination of open inlet and/or open outlet sound power level of fans for standardized installation types.
An estimation (with increased uncertainty) of ducted sound power for fans too small, or otherwise inconvenient, for testing by the in-duct method described in ISO 5136 may also be obtained by the addition of end reflection corrections.
