Describes those quality aspects which are capable of definition but not normally found on a drawing specification. It covers single-piece piston rings of grey, carbidic, malleable, spheroidal graphite cast iron or steel, multi-piece piston rings consisting of cast iron parts and spring components and single-piece and multi-piece rings of steel, in the form of strip steel components or steel segments with spring expander components. Does not establish acceptable quality levels. Applies to all rings up to and including 200 mm diameter covered by the above classification for both reciprocating internal combustion engines and compressors. Includes visible defects, material, raised material caused by marking of rings and machining of periphery and sides - unintentional departure from ideal profile and flatness.
