Scope

IEC/ASTM 63470:2026 establishes a method to determine and quantify the capture efficiency of cooking fume extractors in a test chamber under controlled laboratory conditions using tracer gas techniques. The capture efficiency represents the fraction of the cooking fumes that is directly captured by the fume extractor and does not mix with the room air.
The method applies to cooking fume extractors as defined in IEC 61591.
This test method only applies to airflows up to 720 m3/h.
