ISO 3008-3:2016规定了测定水平方向门和百叶窗组件耐火性的试验方法，这些门和百叶窗组件可能会暴露在下面的火灾中。它适用于所有类型的门和百叶窗组件，这些门和百叶窗组件水平安装在要求建筑物耐火等级的地板或屋顶组件内。 试验方法允许测量完整性，如果需要，还可以测量辐射和隔热。此外，该试验方法还包括测量经受标准火灾的试样的承载能力- 电阻测试。

ISO 3008-3:2016 specifies the test method for determining the fire resistance of horizontally oriented door and shutter assemblies which may be exposed to a fire from the underside. It is applicable to all types of door and shutter assemblies installed in a horizontal orientation within floor or roof assemblies requiring fire-resistance ratings in buildings. The test method allows for the measurement of integrity and, if required, the measurement of radiation and thermal insulation. In addition, this test method includes measurement of the load-carrying ability of the test specimens subjected to a standard fire-resistance test.
