BS EN ISO 16852:2016规定了防止燃烧的阻火器的要求 存在爆炸性气体-空气或蒸汽-空气混合物时的传播。它确立了统一的原则 用于分类、基本结构和使用信息，包括阻火器的标记， 并规定了验证安全要求和确定安全使用极限的试验方法。本国际标准适用于80 kPa至160 kPa的压力和温度 范围为-20°C至+150°C。注1:对于工作条件在范围内但在大气条件外的阻火器， 见7.4。注2:在设计和测试除规定条件外的其他条件下运行的阻火器时 如上所述，本国际标准可用作指南。然而，额外的测试与 建议使用预期条件。当需要高温和高压时，这一点尤为重要 应用在这些情况下，可能需要对试验混合物进行修改。注3:附加标准IMO MSC/Circ。677海事组织海事申请（国际海事组织） 组织）存在。本国际标准不适用于以下情况:可能需要的外部安全相关测量和控制设备，以保持 在规定的安全范围内的操作条件；注4:集成测量和控制设备，如集成温度和火焰传感器 以及故意熔化（固定销）、烧坏（防风雨罩）或弯曲的零件 （双金属带），属于本国际标准的范围。用于蒸汽和气体的爆炸性混合物的阻火器，易于自分解 （如乙炔）或化学性质不稳定的；用于二硫化碳的阻火器，由于其特殊性能；用于气体以外混合物的阻火器- 空气或蒸汽-空气混合物（例如。 较高的氧氮比，氯作为氧化剂等）；内燃机压燃式发动机阻火器试验程序；快速作用阀门、灭火系统和其他隔爆系统。交叉引用:IEC 60079-12014/34/EUISO 3511-1ISO 8421-1:1987ISO 14617-7IEC 60079-4IEC 60079-20-1:2010IMO MSC/Circ。677NFPA 69:2014NFPA 497:2012购买本文件时可获得的所有现行修订均包含在购买本文件中。

BS EN ISO 16852:2016 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.This International Standard is valid for pressures ranging from 80 kPa to 160 kPa and temperatures ranging from -20 °C to + 150 °C.NOTE 1 For flame arresters with operational conditions inside the scope, but outside atmospheric conditions, see 7.4.NOTE 2 In designing and testing flame arresters for operation under conditions other than those specified above, this International Standard can be used as a guide. However, additional testing related specifically to the intended conditions of use is advisable. This is particularly important when high temperatures and pressures are applied. The test mixtures might need to be modified in these cases.NOTE 3 An additional standard IMO MSC/Circ. 677 for maritime application from IMO (International Maritime Organization) exists.This International Standard 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;NOTE 4 Integrated measurement and control equipment, such as integrated temperature and flame sensors as well as parts which, for example, intentionally melt (retaining pin), burn away (weather hoods) or bend (bimetallic strips), is within the scope of this International Standard.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.Cross References:IEC 60079-12014/34/EUISO 3511-1ISO 8421-1:1987ISO 14617-7IEC 60079-4IEC 60079-20-1:2010IMO MSC/Circ. 677NFPA 69:2014NFPA 497:2012All current amendments available at time of purchase are included with the purchase of this document.
