Industrial fans. Determination of fan sound power levels under standardized laboratory conditions - Enveloping surface methods Ingestion-build-251241 who might be faced with1 Scope This part of ISO 13347 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 this part of ISO 13347 are limited only by the practical aspects of the test set up. Dimensional
