The work of preparing Inter
14、national Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison wit
15、h ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technica
16、l committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to
17、 the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 6626-3 was prepared by Technical Committee ISO/TC 22, Road vehicles. ISO 6626 consists of the following parts, under t

BS ISO 6626-3:2008 ISO 6626-3:2008(E) ISO 2008 All rights reserved v Introduction ISO 6626 is one of a series of International Standards dealing with piston rings for reciprocating internal combustion engines. Others are
20、ISO 6621, ISO 6622, ISO 6623, ISO 6624, ISO 6625 and ISO 6627 (see Clause 2 and Bibliography). The common features and dimensional tables presented in this part of ISO 6626 constitute a broad range of variables and, in selecting a particular ring type, the designer will bear in mind the conditions u
21、nder which it will be required to operate.

22、ential dimensions of coil-spring-loaded, nitrided oil control rings made of steel, of piston ring types SOR (with R-shaped groove) and SOV (with V-shaped groove). This part of ISO 6626 applies to coil-spring-loaded, nitrided oil control rings made of steel with a diameter of between 60 mm and 200 mm
23、 inclusive for reciprocating internal combustion engines. It can also be used for piston rings of compressors working under analogous conditions. 2 Normative references The following referenced documents are indispensable for the application of this document.
