出版:International Organization for Standardization

专家解读视频
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-ring manufacturer to piston-ring manufacturer, the interaction between the manufacturer and the client will determine specific design details).This International Standard applies to expander/segment oil-control rings of nominal diameters ranging from 40 mm to 125 mm for reciprocating internal combustion engines. It also applies to piston rings for compressors working under analogous conditions.
