This International Standard specifies the dimensional requirements of high-pressure pipe end-connections for diesel (compression-ignition) engine fuel injection equipment.
It is applicable to externally threaded end-connections of types 1 and 2 having a 60° female cone (see Figures 1 to 3), as well as to the pipe end assemblies of high-pressure fuel injection pipes with outside diameters of up to and including 12 mm (see Table 1).
