标准范围

ISO 10294-5:2005描述了膨胀型防火阀的相关试验要求。它确定了调整ISO 10294-1中描述的试验方法（用于机械阻尼器）以适应膨胀型防火阀所需的微小修改。还包括其他测试，以评估膨胀型防火阀的运行可靠性。本试验适用于根据ISO 10294-2分类为EI挡板的膨胀型防火挡板。如果不添加机械阻尼器，它们就无法达到“S”级，其中包括在环境温度下施加的泄漏限制。

ISO 10294-5:2005 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 will 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.
