適用范圍：This part of EN 1366 specifies a test method for determining the fire resistance of smoke extractionducts that are used for single compartment applications only. In such applications, the smokeextraction system is only intended to function up to flashover (typically 600 °C).This method of test is only suitable for ducts constructed from non-combustible materials (euroclass A1 and A2-s1, d0).It is applicable only to four sided and circular ducts. One, two and three sided ducts are not covered.This test has been designed to cover horizontal smoke extraction ducts intended for singlecompartment applications only.This test method of part 9 is applicable only to smoke extraction ducts that do not pass through intoother fire compartments. It represents fire exposure of a developing fire (pre-flashover). For smokeextraction ducts that pass through into other compartments, the method of test described in EN 1366-8 should be used.The smoke extraction duct is part of the smoke extraction system which also includes smoke controldampers and smoke extract fans.The method described in this test standard is complex and requires sophisticated instrumentation. It isnot recommended therefore to try to test multiple assemblies in this test.
