This SAE Standard specifies the quality aspects that are capable of definition but not normally found on a drawing specification.
The difficulty of trying to define in absolute terms the quality attainable in normal commercial manufacture of piston rings is well known. in this document the commonly encountered aspects of quality in terms of casting defects and other departures from ideal are quantified. Many minor defects are clearly quite acceptable; other defects because of size or numbers are inadmissible.
