Fire resistance tests for service installations - Smoke extraction ducts Ingestion-build-189776 BS IEC 61189-5-2 is an1 Scope This Part of this document specifies a test method for determining the fire resistance of smoke extraction ducts. It is applicable only to smoke extraction ducts that pass through another fire compartment from the fire compartment to be extracted in case of fire. It represents fire exposure of a fully developed fire. This method of test is only applicable to fire resisting ducts that have passed the test for the appropriate period to EN 13661
