ISO 6627 pdf download Internal combustion engines — Piston rings — Expander/segment oil-control rings
1 Scope
This International Standard specifies the essential dimensional features of expander/segment oil-control rings,without providing a complete product description (because expander-spacer design varies from piston-ringmanufacturer to piston-ring manufacturer,the interaction between the manufacturer and the client wildetermine specific design details).
This International Standard applies to expanderlsegment oil-control rings of nominal diameters ranging from40 mm to 125 mm for reciprocating internal combustion engines for road vehicles and other applications. ltalso applies to piston rings for compressors working under analogous conditions.
