This part of ISO 13555 establishes the preconditioning phase of the procedure for checking the dynamic setting of fuel injection equipment fitted to diesel engines. Such preconditioning is carried out prior to the dynamic timing measurement of the fuel injection pump setting according to ISO 13555-2, in which timing measurement devices are used, based on the principle of sensing a pressure rise in the high-pressure pipe by either clamp-on (clip-on) pressure transducers that measure high-pressure pipe dilation or by inline pressure transducers.
