标准范围
This part of ISO 10294-5 describes the test requirements related to intumescent fire dampers. It identifies theminor modifications needed to adapt the test method described in ISO 10294-1 (which was intended formechanical dampers) to suit intumescent fire dampers. Additional tests are included to give an assessment ofthe operational reliability of intumescent fire dampers.This test is intended for intumescent fire dampers that are expected to be classified as EI dampers inaccordance with ISO 10294-2. Without the addition of a mechanical damper, they are unable to achieve the“S” classification, which includes a leakage limit imposed at ambient temperatures.
