This document specifies the dimensional requirements of high-pressure liquid fuel pipe end-connections for gasoline (spark ignition) engine fuel injection equipment.
It is applicable to externally threaded end-connections having a 60° concave cone (see Figure 1), as well as to the pipe end assemblies of high-pressure fuel injection pipes with outside diameters of up to and including 10 mm (see Table 1).
BSI recommends this version of standard for organisations operating in or with the UK. The ISO edition is available here if required.
