ISO 3008-2:2017规定了确定电梯层门组件耐火性的试验方法，这些组件可能暴露在层门侧面的火灾中。本程序适用于所有类型的电梯层门组件，这些电梯层门组件用作进入建筑物内电梯的方式，旨在提供防火屏障，防止火灾通过电梯井蔓延。 该程序允许测量完整性，如果需要，还可以测量辐射和隔热。 除了验证试样是否可操作外，试验前的机械调节不包括其他要求。

ISO 3008-2:2017 specifies the method of test for determining the fire-resistance of lift landing door assemblies which can be exposed to a fire from the landing side. The procedure is applicable to all types of lift landing door assemblies used as a means of access to lifts in buildings and which are intended to provide a fire barrier to the spread of fire via the lift well. The procedure allows for the measurement of integrity and, if required, the measurement of radiation and thermal insulation. No requirements other than the verification that the specimen is operational are included for the mechanical conditioning before the test.
