Cooking fume extractors – Method for measuring the capture efficiency

Scope

This document 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 is the fraction of the cooking fumes that are directly captured by the fume extractor and do 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.
