Part 9 Terms and definitions’. The terms and definitions in this part of ISO apply to piston rings for reciprocating 66221-5 combustion engines.

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. For dated references, only the edition cited applies. Standards are also reviewed periodically; a standard along with amendments is reaffirmed when such review indicates that no changes are needed; if the review indicates that changes are needed, it is taken up for revision. Every care has been taken to ensure that the file is suitable for use by ISO member bodies.

For undated references, the latest edition of the referenced 662-15 including any amendments applies. ISO consists of the following parts, under the general title Internal combustion engines — Piston rings: Key 1 outside chamfered edge 2 peripheral edge 3 side face edge 4 inside chamfered edge Figure 5 — Chamfered edges 5. They may also be used for piston rings of compressors working under analogous conditions. This does not preclude the free use, in course of imple- menting the standard, of necessary details, such as symbols and sizes, type or grade designations.

This second edition cancels and replaces the first edition ISO These terms designate either types of piston rings or certain characteristics 66221-5 phenomena of piston rings. Pin point or burry light 6.

BS ISO – Internal combustion engines. Piston rings. Quality requirements

This Indian Standard has been developed from Doc No.: The terms and definitions in this part of ISO apply to piston rings for reciprocating internal combustion engines. Combinations of configurations listed in Tables 2 to 5 along with those in Table 1 are shown as “common features” in the relevant ISO Standard referenced in each table. For undated references, the latest edition of the referenced document including any amendments applies.

The work of preparing International Standards is normally carried out through ISO technical committees. For dated references, only the edition cited applies. Basis of limits and fits: Certain conventions are, however, not identical to those used in Indian Standards.

Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. The main task of technical committees is to prepare International Standards. Attention is particularly drawn to the following: However, only the terms given in the official languages can be considered as ISO terms.

Users of Indian Standards should ascertain that they are iiso possession of the latest amendments or edition by referring to the latest issue of ‘BIS Catalogue’ and ‘Standards: 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.

In this adopted standard, reference appear to the following International Standard for which Indian Standard also exists. Adobe is a trademark of Adobe Systems Incorporated.
