标准范围

ISO 16852:2008规定了当存在爆炸性气体-空气或蒸汽-空气混合物时防止火焰传播的阻火器的要求。它为阻火器的分类、基本结构和使用信息（包括标记）制定了统一的原则，并规定了验证安全要求和确定安全使用极限的测试方法。ISO 16852:2008适用于80 kPa至160 kPa的压力和-20°C至+150°C的温度。ISO 16852:2008不适用于以下情况:可能需要将操作条件保持在既定安全限度内的外部安全相关测量和控制设备；用于蒸汽和气体爆炸性混合物的阻火器，这些混合物往往会自-分解(例如乙炔)或化学上不稳定的；用于二硫化碳的阻燃剂，由于其特殊性能；预期用途为气体-空气或蒸汽-空气混合物以外的混合物的阻火器（例如较高的氧-氮比、氯作为氧化剂等）；内燃压燃式发动机阻火器试验规程；快速作用阀门、灭火系统和其他防爆系统；与防爆设备集成或组合的阻火器，如鼓风机、风扇、压缩机和泵。

ISO 16852:2008 specifies the requirements for flame arresters that prevent flame transmission when explosive gas-air or vapour-air mixtures are present. It establishes uniform principles for the classification, basic construction and information for use, including the marking of flame arresters, and specifies test methods to verify the safety requirements and determine safe limits of use.ISO 16852:2008 is valid for pressures ranging from 80 kPa to 160 kPa and temperatures ranging from -20 °C to +150 °C.ISO 16852:2008 is not applicable to the following:

• external safety-related measurement and control equipment that might be required to keep the operational conditions within the established safe limits;
• flame arresters used for explosive mixtures of vapours and gases, which tend to self-decompose (e.g. acetylene) or which are chemically unstable;
• flame arresters used for carbon disulphide, due to its special properties;
• flame arresters whose intended use is for mixtures other than gas-air or vapour-air mixtures (e.g. higher oxygen-nitrogen ratio, chlorine as oxidant, etc.);
• flame arrester test procedures for internal-combustion compression ignition engines;
• fast acting valves, extinguishing systems and other explosion isolating systems;
• flame arresters integrated or combined with explosion-protected equipment, such as blowers, fans, compressors and pumps.
