Internal combustion engines -- Piston rings -- Part 2: Inspection measuring principles
This standard has been revised by ISO 6621-2:2003
This part defines the measuring principles to be used for measuring piston rings. Applies to piston rings up to and including 200 mm diameter for reciprocating internal combustion piston engines. May be used for piston rings for compressors working under analogous conditions. Several figures illustrate shapes and reference quantities of concern.
