Internal combustion engines — Piston rings — Part 3: Coil-spring-loaded oil control rings made of steel

Scope

ISO 6626-3:2008 specifies the essential dimensions of coil-spring-loaded, nitrided oil control rings made of steel, of piston ring types SOR (with R-shaped groove) and SOV (with V-shaped groove).
ISO 6626-3:2008 applies to coil-spring-loaded, nitrided oil control rings made of steel with a diameter of between 60 mm and 200 mm inclusive for reciprocating internal combustion engines. It can also be used for piston rings of compressors working under analogous conditions.
