ISO 13348:2007 Preview
Industrial fans -- Tolerances, methods of conversion and technical data presentation
This standard was last reviewed and confirmed in 2010. Therefore this version remains current.
ISO 13348:2007 specifies performance tolerances and the technical data presentation of industrial fans of all types. It does not apply for fans designed solely for low-volume air circulation, such as those used for household or similar purposes (ceiling and table fans, extractor fans, etc.).
ISO 13348:2007 covers the four installation categories defined in ISO 5801: A, free inlet, free outlet; B, free inlet, ducted outlet; C, ducted inlet, free outlet; D, ducted inlet, ducted outlet.
