ISO 14114:2017适用于从气瓶阀或管束出口连接延伸至主切断阀出口连接的乙炔气瓶歧管系统。它规定了用于焊接、切割和相关工艺的乙炔供应的气缸歧管系统的设计、材料和测试要求。 ISO 14114:2017适用于乙炔气瓶歧管系统，在该系统中，乙炔单个气瓶或乙炔束连接在一起，用于集体抽气。 注:关于单个位置（例如仓库内或连接到歧管系统）的单个乙炔气瓶/捆数量限制，存在国家法规。 ISO 14114:2017还涵盖了分解阻滞剂的测试程序。

ISO 14114:2017 applies to acetylene cylinder manifold systems extending from the cylinder valve or the bundle outlet connections to the outlet connection of the main shut-off valve. It specifies requirements for design, materials and testing of cylinder manifold systems for the supply of acetylene for use in welding, cutting and allied processes. ISO 14114:2017 applies to acetylene cylinder manifold systems in which acetylene single cylinders or acetylene bundles are coupled for collective gas withdrawal. NOTE National regulations exist regarding limitation of the amount of single cylinders/bundles of acetylene on a single location (e.g. in warehouse or connected to a manifold system). ISO 14114:2017 also covers a test procedure for decomposition blockers.
