ISO 16852:2016规定了当存在爆炸性气体 - 空气或蒸汽 - 空气混合物时阻止火焰传播的阻火器的要求。建立了分类，基本构造和使用信息的统一原则，包括对火焰捕获器的标识，并规定了验证安全要求和确定安全使用限制的测试方法。 本国际标准适用于80 kPa至160 kPa的压力范围，温度范围为-20°C至150°C。 注1:对于操作条件在范围内但外部大气条件下的阻火器，请参阅7.4。 注2:在设计和测试阻火器以在上述以外的条件下运行时，本国际标准可用作指导。但是，建议使用与预期使用条件有关的附加测试。当应用高温和高压时，这尤其重要。在这些情况下，测试混合物可能需要修改。 注3附加标准IMO MSC/Circ。存在海事组织（国际海事组织）海上申请的677。 ISO 16852:2016不适用于以下内容: - 外部安全相关的测量和控制设备，可能是re

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. ISO 16852:2016 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.
