3、1998 BSI 04-1999 ISBN 0 580 29418 8 National foreword This British Standard reproduces verbatim ISO 4250-3:1997 and implements it as the UK national standard. It supersedes BS AU 50-4-3.1:1991, which is withdrawn. The UK participation in its preparation was entrusted to Technical Committee AUE/4, Ty
4、res and wheels for motor vehicles, which has the responsibility to: aid enquirers to understand the text; present to the responsible international/European committee any enquiries on the interpretation, or proposals for change, and keep the UK interests informed; monitor related international and Eu
5、ropean developments and promulgate them in the UK. A list of organizations represented on this committee can be obtained on request to its secretary. Cross-references The British Standards which implement international or European publications referred to in this document may be found in the BSI Sta
6、ndards Catalogue under the section entitled “International Standards Correspondence Index”, or by using the “Find” facility of the BSI Standards Electronic Catalogue. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible
7、 for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations.

14、). 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, governmental and no
15、n-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. Draft International Standards adopted by the technical committees are circulated to the member bodies
16、 for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard ISO 4250-3 was prepared by Technical Committee ISO/TC 31, Tyres, rims and valves, Subcommittee SC 6, Off-the-road tyres and rims. This second edition c
17、ancels and replaces the first edition (ISO 4250-3:1987), of which it constitutes a technical revision. ISO 4250 consists of the following parts, under the general title Earth-mover tyres and rims: Part 1: Tyres designations and dimensions; Part 2: Loads and inflation pressures; Part 3: Rims. Annex A
18、 of this part of ISO 4250 is for information only. Descriptors: Site equipment, self-propelled machines, earth-moving equipment, rims, dimensions, designation.

19、 AU 50-4-3.1a:1998 BSI 04-19991 1 Scope ISO 4250 consists of three parts (see the Foreword) laying down the technical elements relating to designation and dimensions of tyres and rims for earth-moving machinery: it also gives load tables for these tyres. This part of ISO 4250 sets out the designatio
20、n, contours and dimensions for rims for narrow and wide base off-road tyres primarily intended for earth-moving machinery. Annex A gives details of sealing ring grooves and O-rings for earth-mover rims. NOTETerms used are in accordance with ISO 3911:1977, Wheels/rims Nomenclature, designation, marki
21、ng and units of measurement. 2 Rim identification 2.1 Codes shall be used to identify: a) specified rim diameter, D (see Table 6); b) nominal width between flanges; c) nominal flange height or rim profile designations. 2.2 The rim marking shall consist of codes for: a) specified rim diameter, D; b)
22、nominal width between flanges. The markings shall be on the weather side of the rim and visible when the tyre is mounted on the rim Where a disk is fitted by the rim/wheel manufacturer, the marking shall appear on either the disc or rim base. Loose flanges shall be marked on an externally visible su
23、rface. The marking shall indicate nominal height and nominal diameter. 3 Rim contours Rim contours are given in Figure 1 to Figure 5 and Table 1 to Table 5. 4 Rim knurling Rim knurling details are given in Figure 6 and Table 6. 5 Rim loads and inflation pressures The load and inflation pressure impo
24、sed on the rim and wheel shall not exceed the rim and wheel manufacturers recommendations, even though the tyre may be approved for a higher load or inflation pressure. Consult the rim and wheel manufacturer to determine if rim and wheel capacities are adequate for the intended service. 6 Rim dimens
25、ions Rim dimensions are standardized for size and contour only, and for particular tyre and rim combinations designated to ensure proper mounting and fit of the tyre to the rim.
