Investigation of a tracer gas method to evaluate smoke leakage of door assemblies

Research output: Book/ReportReport

Abstract

A pilot test series has been performed to study the possibility to use carbon dioxide produced by the burners of a test furnace as a tracer gas to measure the fire gas leakage of door assemblies. The experiments show that a test method based on tracer gas technique can be developed avoiding the drawbacks of the proposed ISO test method DP 5925 part 3 based on the use of an enclosure. The investigated method applies well for use in connection with the standard fire resistance tests as well as for leakage measurements in ambient and medium temperature ranges. A special test door suitable for theoretical estimation of leakage rates was used in the test. The agreement between the experimental and theoretical results is satisfactory.
