3、n) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing international Standards is normally carried out through IS0 technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be rep
4、resented on that committee. International organizations, govern- mental and non-governmental, in liaison with ISO, also take part in the work. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Sta
5、ndards adopted by the technical committees are circulated to the member bodies for voting. Publication as an Inter- national Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard IS0 6194-5 was prepared by Technical Committee iSO/TC 131, Fluid power
6、systems. IS0 6194 consists of the following parts, under the general title Rotary shaft lip type seals: - Part I: Nominal dimensions and tolerances - Part 2: Vocabulary - Part 3: Storage, handling and installation - Part 4: Performance test procedures - Part 5: Identification of visual imperfections

9、IS0 6194-5:1990(E) Introduction Lip type seals are used for retaining fluid or grease in equipment em- ploying rotating shafts. In some instances, the shaft is stationary and the housing rotates. Sealing of a lip type seal with low differential pressure is normally a result of s designed interferenc
10、e fit between the shaft and the flexible sealing element, which is usually fitted with a garter spring. An interference fit between the outside surface of the seal and the housing bore surface retains the seal in the housing and prevents leakage at the outer diameter. .*. III Copyright International

12、: Identification of visual imperfections 1 Scope This part of IS0 6194 shows and identifies visual imperfections on typical rotary shaft lip type seals, dimensionally standardized in IS0 6194-1, as a con- venience for purchasers and manufacturers of rotary shaft lip type seals in their discussions a
13、bout the importance of imperfections in different applications. It defines and classifies typical surface imperfec- tions that often impair the function of the rotary shaft lip type seal. 2 Normative references The following standards contain provisions which, through reference in this text, constit
14、ute provisions of this part of IS0 6194. At the time of publication, the editions indicated were valld. All standards are subject to revision, and parties to agreements based on this part of IS0 6194 are encouraged to investi- gate the possibility of applying the most recent edi- tions of the standa
15、rds indicated below. Members of IEC and IS0 maintain registers of currently valid in- ternational Standards. IS0 5598:1985, Fluid power systems and components - Vocabulary.
