标准范围

ISO/TS 27469:2010规定了用于确定以下内容的方法:安装在通风系统中的防火阀防止火灾和热量通过指定的防火分区蔓延的能力；典型等级见ISO 13702:1999表C.5。石油、石化和天然气工业，特别是海上装置中防火阀的运行可靠性；安装在通风系统中的防火阀承受易燃气体爆炸可能产生的爆炸超压的能力。ISO/TS 27469:2010适用于不同类型熔炉的不同启动操作，因此没有详细描述测试开始时测试条件的公差。火灾测试只能对正在执行的致动机构进行有限的评估，并且可能需要额外的测试来充分评估其操作可靠性。

ISO/TS 27469:2010 specifies a method for determining the following:

1. ability of fire dampers installed in ventilation systems to prevent the spread of fire and heat through designated fire divisions; typical ratings are given in ISO 13702:1999, Table C.5.
2. fire damper operational reliability in the petroleum, petrochemical and natural gas industries, particularly offshore installations;
3. ability of fire dampers installed in ventilation systems to withstand blast overpressures that may result from the explosion of a flammable gas.

ISO/TS 27469:2010 applies to different start-up operations for different types of furnace and, therefore, tolerances in test conditions at the beginning of the test are not described in detail. The fire test enables only a limited assessment of the actuating mechanism being carried out and additional tests can be necessary to fully evaluate its operational reliability.
