ISO 6627 pdf download – lnternal combustion engines -Pistonrings – Expanderl segment oil-control rings.
ISO 6627 specifies the essential dimensional features 01 expander/segment oil-control rings. without providing a corvlete product desaiption (because expander-spacer design varies from plston-nng manufacturer to piston-ring manufacturer, the interaction between the manufacturer and the client wl determine specific design details).
This International Standard applies to expanderlsegment oil-control rings of nominal diameters ranging from 40mm to 125 rrvri (or reciprocating Internal combustion engines (or road vehicles and other applications. It also applies to piston rings for compressors working under analo9ous conditions.
