This International Standard specifies the functional require-ments of a range of high-pressure pipes for use on benches for the testing and setting of fuel injection pumps intended for compression ignition (diesel) engines.
Only dimensions and requirements affecting the hydraulic characteristics of the pipes are defined. Other requirements, such as the type of end cohnections or shape of the pipes when bent, are not included as these depend on the connections pro-vided on the pump outlets and injector inlets, and on the design features of individual pumps and test benches.
