BS ISO 4093:1999

This standard BS ISO 4093:1999 Diesel engines. Fuel injection pumps. High-pressure pipes for testing is classified in these ICS categories:

• 43.060.40 Fuel systems

This International Standard specifies the functional requirements of a range of high-pressure pipes for use on benches for the testing and setting of fuel injection pumps intended for diesel engines.

Only dimensions and requirements affecting the hydraulic characteristics of the pipes are specified. Other requirements, such as the type of end connections or shape of the pipes when bent, are not included as these depend on the connections provided on the pump outlets and injector inlets, and on the design features of individual pumps and test benches.

This International Standard applies to a range of pipes to enable the pump engine manufacturer to choose a suitable type of pipe for pump deliveries up to 300 mm³/stroke/cylinder. The particular pipe to be used shall be identified by the pump manufacturer in the test schedule for each individual pump type and application.
