Fire-resistance tests. Fire dampers for air distribution systems - Intumescent fire dampers subscription-only ISO 21809-11 states qualification/testing for1 Scope This part of ISO 10294 5 describes the test requirements related to intumescent fire dampers. It identifies the minor modifications needed to adapt the test method described in ISO 10294 1 (which was intended for mechanical dampers) to suit intumescent fire dampers. Additional tests are included to give an assessment of the operational reliability of intumescent fire dampers. This test is intended for intumescent fire dampers that are expected
