Internal combustion engines. Piston rings. Expander/segment oil-control rings1 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 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

the results obtained depend as much on the process of performing the measurements as they depend on the engine and test method

as well as the procedure for assessing leaf injury
