ISO 13555-2:2002 specifies a test method for referencing the pressure rise in the high-pressure pipe of a diesel fuel injection system consisting of fuel injection pump, high-pressure pipe or pipes and injector or injectors, as part of the procedure for checking the dynamic setting of fuel injection equipment fitted to diesel engines (the pressure rise being related to the start of pumping of fuel at the fuel injection pump and the start of injection). It is not applicable to unit injector systems or common rail systems and, unless otherwise noted by the original equipment manufacturer (OEM), might not be applicable to systems incorporating line/cylinder disable at idle, fuel injection equipment with electronic controls that control timing or systems incorporating pilot or pre-injection features. The test method does not cover the setting of diesel fuel injection timing, for which reference is to be made to the vehicle, engine or fuel injection manufacturer's data or all these.
