Fire resistance tests for service installations - Single compartment smoke extraction ducts Ingestion-build-189776 ISO 15883-4 guideline assists you1 Scope This part of EN 1366 specifies a test method for determining the fire resistance of smoke extraction ducts that are used for single compartment applications only. In such applications, the smoke extraction 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 (euro class A1 and A2 s1, d0). It is applicable only to four sided and circular
