With the publication of this standard IS Part 9 shall be treated as withdrawn. Due to its wedge shape, any radial movement of the ring will alter its axial clearance and thus minimize the build-up of combustion residues. Copyright BIS has the copyright of all its publications.
The terms and definitions in this part of ISO apply to piston rings for reciprocating internal combustion engines. However, only the terms given in the official languages can be considered as ISO terms. Due to its wedge shape, any radial movement of the ring will alter its axial clearance and thus minimize the build-up of combustion residues. ISO shall not be held responsible for identifying any or all such patent rights. They may also be used for piston rings of compressors working under analogous conditions.

These terms designate either types of piston rings or certain characteristics and phenomena of piston rings. ISO consists of the following parts, under the general title Internal combustion engines — Piston rings: Part 9 Terms and definitions’. Certain conventions are, however, not identical to those used in Indian Standards.
The terms and definitions in this part of ISO apply to piston rings for reciprocating internal combustion engines. Attention is particularly drawn to the following: Coil-spring-loaded oil control rings of narrow width made of cast iron [11] ISOInternal combustion engines — Piston rings — Part 3: Details of the software products used to create this PDF file can be found in the General Info relative to the file; the PDF-creation parameters were optimized for printing.
