23、es (ISO member bodies). The work of preparing International 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
24、, governmental and non-governmental, in liaison with 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 IS
25、O/IEC Directives, Part 2. The main task of technical 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
26、member bodies casting a vote. Attention is drawn to 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 6194-2 was prepared by Technical Committee ISO/TC 131, Fluid power
27、systems, Subcommittee SC 7, Sealing devices. This second edition cancels and replaces the first edition (ISO 6194-2:1991), which has been technically revised.

36、d in equipment where the differential pressure is relatively low. Typically, the shaft rotates, and the housing is stationary, although in some applications the shaft is stationary, and the housing rotates. Dynamic sealing is normally the result of a designed interference fit between the shaft and a
37、 flexible element incorporated in the seal. Similarly, a designed interference fit between the outside diameter of the seal and the diameter of the housing bore retains the seal and prevents static leakage. Careful storage, handling and proper installation of all seals are necessary to avoid hazards
38、, both prior to and during installation, that can adversely affect service life.

39、 quipements dont la pression diffrentielle est relativement faible. Habituellement, larbre tourne et le logement reste fixe mais, dans certaines applications, cest larbre qui est fixe et le logement qui tourne. Une tanchit dynamique est normalement le rsultat dun ajustement serr volontaire entre lar
40、bre et un lment dtanchit souple incorpor la bague dtanchit. De faon similaire, un ajustement serr volontaire entre le diamtre extrieur de la bague dtanchit et le diamtre dalsage du logement retient la bague dtanchit et empche les fuites statiques.
