This information report establishes the part numbers and/or description of the critical components and operational guidelines for the Standard Hydraulic Impulse Machine for testing hydraulic hose assemblies, tubing, coils, and fittings and may be used for similar fluid system components, if desired. The Standard Impulse Machine is established for the following purposes: As referee in the event of conflicting data from two or more non-standard impulse machines. Such a referee machine might be built by an impartial testing activity; A design guide for future machines being built by manufacturers and users, or the upgrading of present machines; and A design guide for higher pressure machines or special purpose machines being designed. It is not the intention of this information report to obsolete present machines.
