标准摘要
[中文适用范围]： 本文件规定了柴油（压燃式）发动机上使用的高压燃油喷射设备部件端部连接的尺寸要求。 它适用于外螺纹 60° 内锥体（见图 1、2、5 和 6），并适用于高压燃油喷射管组件，其管外径为： ——整体内螺纹最大至 12 mm（含）锥体（见表1）； - 对于制造的阴锥体，最大（含）9 毫米（见表 2）。 本文件中引用的管道连接端的详细信息显示在 ISO 13296 中。 [外文原描述]： ISO 2974:2018 specifies the dimensional requirements of end-connections for high-pressure fuel injection equipment components, used on diesel (compression-ignition) engines. ISO 2974:2018 is applicable to externally threaded 60° female cones (see Figures 1, 2, 5, and 6) and intended for use with high-pressure fuel injection pipe assemblies with tube outside diameters of: - up to and including 12 mm for integral female cones (see Table 1); and - up to and including 9 mm for fabricated female cones (see Table 2). Details of the pipe connection ends referenced in this document are shown in ISO 13296.
