This document specifies methods for measuring the aerodynamic and acoustic characteristics of cowls and roof outlets used in both natural and mechanical ventilation. Only those cowls and roof outlets fitted onto ducts which project above the roof surface are covered by the present standard.
Regarding the assisted cowls, only the fan assisted cowls are covered by the present standard, other types (such as injection assisted cowls) being too recent to be adequately considered for the time being.

Concerning performance testing of odour extraction (clause 7), this European
standard refers entirely to IEC 61561:1997, clause 13. Experience from a large number of
performance tests on both extracting and re-circulating hoods shows that hoods with average
or inferior performance in a real situation, can achieve excellent performance numbers (odour
reduction factors) in the test. The direct reference to IEC 61561:1997, clause 13 should be
removed and a modified test method should be included in...
