Describes the general characteristics of piston rings, and individual dimensional criteria. Provides a system for coding, designation and marking of piston rings. Applies to all rings up to and including 200 mm diameter covered by the classification of both reciprocating internal combustion engines and compressors. Includes reference, terminology, notches to prevent ring rotation, machining and coating surfaces, treated surfaces and packing. Includes several tables and figures.
