建筑单元和构件的燃烧试验.服务设施的燃烧试验.第2部分:线性接缝(缝隙)密封件

[中文适用范围]： 本部分ISO 10295规定了加热条件、测试方法和评估线性接缝密封件在接缝处保持防火分隔构件的防火完整性和隔热性能的能力的标准。测试的目的是评估线性接缝密封件的完整性和隔热性能，包括接缝设计用于容纳运动且宽度大于20毫米时的运动影响。本部分ISO 10295无意提供有关烟雾和/或气体泄漏率或烟雾传输或产生的定量信息，尽管在描述试样在测试期间的一般行为时可以记录这些现象。本部分ISO 10295无意评估已有特殊测试程序的接缝密封件，例如门、隔断、穿透件、管道、风管和电缆。 [外文原描述]： ISO 10295-2:2009 specifies the heating conditions, methods of test and criteria for the evaluation of the ability of a linear joint seal to maintain the fire integrity and thermal insulation of a fire-separating element at the joint being sealed. The purpose of the tests is to assess the integrity and insulation performance of the linear joint seals, including the effects of induced movement in those cases where the joint is designed to accommodate movement and has a width greater than 20 mm. It is not the intention of this part of ISO 10295-2:2009 to provide quantitative information on the rate of leakage of smoke and/or gases, or on the transmission or generation of fumes, although such phenomena can be recorded in describing the general behaviour of specimens during the test. It is not the intention of this part of ISO 10295-2:2009 to evaluate joint seals where special test procedures already exist, e.g. doors, partitions, penetrations, pipes, ducts and cables.
