ISO 8434-2:20 07规定了37°扩口连接器的设计和性能的一般和尺寸要求，这些连接器适用于外径为6mm至50.8 mm（含6mm）的黑色金属和有色金属管。这些连接器用于规定压力和温度范围内的流体动力和一般应用。 它们用于将管道和软管配件连接到符合ISO 6149标准的端口？1、ISO 1179？1、ISO 9974？1和ISO 11926？1.（相关软管接头规范见ISO 12151？5。） ISO 8434-2:20 07还规定了37°扩口连接器的性能和鉴定测试。

ISO 8434-2:2007 specifies general and dimensional requirements for the design and performance of 37° flared connectors that are suitable for use with ferrous and non-ferrous tubes with outside diameters from 6 mm to 50,8 mm, inclusive. These connectors are for use in fluid power and general applications within the limits of pressure and temperature specified. They are intended for the connection of tubes and hose fittings to ports in accordance with ISO 6149？1, ISO 1179？1, ISO 9974？1 and ISO 11926？1. (See ISO 12151？5 for related hose fitting specification.) ISO 8434-2:2007 also specifies a performance and qualification test for 37° flared connectors.
