ISO 10294-5膨脹防火閥耐火試驗 – 適用范圍
本部分描述了與膨脹型防火閥有關的測試要求。它確定了為適應ISO 10294-1（旨在用于機械風門）中描述的測試方法以適應膨脹型防火風門而需要進行的細微修改。包括其他測試以評估膨脹型防火閥的運行可靠性。
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 to be classified as EI dampers in accordance 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.
