耐火试验. 第2部分: 电梯门组件

[中文适用范围]： 本文件规定了确定可从层站侧暴露于火灾的电梯层站门组件的耐火性的测试方法。 该程序适用于所有类型的电梯层门组件，这些组件用作进入建筑物电梯的手段，旨在为通过电梯井道蔓延的火灾提供防火屏障。 该程序允许测量完整性，如果需要，还可以测量辐射和隔热。 除了验证样本是否可操作之外，测试前的机械调节不包括任何其他要求。 [外文原描述]： 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.
