8、ion) is a worldwide federation of national standards bodies (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 r
9、epresented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the Inter- national Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standar
10、ds are drafted according to the rules given in the ISO/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 Internationa
11、l Standard requires approval by at least 75 % of the 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 3547-6 was pre
12、pared by Technical Committee ISO/TC 123, Plain bearings, Subcommittee SC 5, Quality analysis and assurance. This part of ISO 3547 cancels and replaces ISO 12307-2:2000, which has been technically revised. ISO 3547 consists of the following parts, under the general title Plain bearings Wrapped bushes

15、of wrapped bushes (see ISO 3547-2:2006, method C) and describes the necessary checking methods and measuring equipment. Wrapped bushes in the free condition are flexible, but after insertion they adapt largely to the shape of the housing bore due to the interference between the outside diameter of t
16、he bush and the housing bore. NOTE 1 All dimensions in this part of ISO 3547 are given in millimetres except where otherwise noted/designated. NOTE 2 The dimensions and tolerances of wrapped bushes are given in ISO 3547-1. NOTE 3 Checking of the wall thickness is the subject of ISO 3547-7. NOTE 4 Ch
17、ecking of the outside diameter of wrapped bushes is the subject of ISO 3547-5. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the ref

21、 checking The free diameter of a wrapped bush is not measured directly because of the flexible nature of the components. To check the inside diameter, Di, ch, the bush is pressed into a ring gauge whose nominal diameter corresponds to the dimension of the housing. For bushes specified in ISO 3547-1,
22、 the tolerance class of housing bore is normally H7. When the bush is pressed into the ring gauge, it is possible that there is a permanent reduction in the outside diameter. The inside diameter, Di, ch, is measured with a three-point measuring instrument or with a GO or a NO GO gauge. In order to e
23、nable the supplier and the user to compare results of this test it shall be agreed whether results shall be obtained by measuring or by gauging. 5 Test equipment 5.1 Ring gauge Unless otherwise agreed between supplier and user, the dimensions shown in Figure 1 and given in Table 2 are valid for the
