11、:52 GMT+00:00 2006, Uncontrolled Copy, (c) BSI BS AU 50-4.5.2:1996 ii BSI 07-1999 National foreword This Subsection of Part 4 of BS AU 50 has been prepared by Technical Committee AUE/4 and is identical with ISO 3739-3:1995 Industrial tyres and rims Part 3: Rims, published by the International Organi
12、zation for Standardization (ISO). It covers rim profiles for use with pneumatic tyres and solid tyres with the equivalent profile. The corresponding tyre details are dealt with in Subsections 5.2, 5.3 and 5.4 (of BS AU 50-1). Tyre and rim details for cyclindrical and conical base rubber solid tyres
13、(metric series) are dealt with in Subsection 5.6 of BS AU 50-1. Other Parts of this standard are as follows: Part 1: Tyres; Part 2: Wheels and rims; Part 3: Valves. Warning. The wheel manufacturer should be consulted to determine whether the rim and wheel is of sufficient strength for the intended s
14、ervice. In particular, care has to be taken to ensure that the wheel will withstand the maximum pressure of any tyre that can be fitted in accordance with BS AU 50-1.5.2:1994 or BS AU 50-1.5.3:1994. This pressure could exceed 1 000 kPa (10 bar) for both diagonal and radial tyres. Cross-references Th
15、e Technical Committee has reviewed the provisions of ISO 3911:1977 to which normative reference is made in the text, and has decided that they are acceptable for use in conjunction with this standard. A British Standard does not purport to include all the necessary provisions of a contract. Users of
16、 British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pages i and ii, pages 1 to 6, an inside back cover and a back
17、 cover. This standard has been updated (see copyright date) and may have had amendments incorporated. This will be indicated in the amendment table on the inside front cover.

18、opy, (c) BSI BS AU 50-4.5.2:1996 BSI 07-19991 1 Scope This part of ISO 3739 specifies the main requirements, including size designation and marking, of 5 tapered and flat base rims with diameters not exceeding rim diameter code 15 for pneumatic tyres, and for solid tyres for pneumatic tyre rims, pri
19、marily intended for industrial vehicles for use on prepared surfaces. ISO 3739-1 gives the designation, dimensions and marking, and ISO 3739-2 the load ratings of pneumatic tyres (metric series). ISO 10499 covers the designation, dimensions and marking of rubber solid tyres (metric series) for pneum
20、atic tyre rims. Rim dimensions are specified for size and contour only. The tyre and the wheel/rim manufacturers have to be consulted for confirmation of the suitability of the tyre/rim combinations, particularly with regard to rim profile and wheel strength. 2 Normative reference The following stan
21、dard contains provisions which, through reference in this text, constitute provisions of this part of ISO 3739. At the time of publication, the edition indicated was valid. All standards are subject to revision, and parties to agreements based on this part of ISO 3739 are encouraged to investigate t
22、he possibility of applying the most recent edition of the standard indicated below. Members of IEC and ISO maintain registers of currently valid International Standards. ISO 3911:1977, Wheels/rims Nomenclature, designation, marking, and units of measurement. 3 Definitions For the purposes of this pa
23、rt of ISO 3739, the definitions given in ISO 3911 apply. 4 Designation and marking Rim designation and marking shall be in accordance with ISO 3911:1977, clauses 3 and 4 respectively. 5 Rim profiles 5.1 Existing rims Profiles of existing rims shall be as given in Annex A. The flange widths include e
24、dge radius. The portion of the flange beyond the minimum width shall be lower than the highest point of the flange. 5.2 Additional rims As far as possible, existing rims (see 5.1) should be used for the metric series of tyres; only if absolutely necessary should new profiles be considered. If additi
25、onal rims are designed, the requirements in 5.2.1 and the recommendation in 5.2.2 apply. 5.2.1 Requirements The new rim width code shall be chosen from the following range: 2.50; 3.25; 4.00; 5.00; 6.50; 8.00; 10.00 Any rim profile shall be independent from the rim diameter, i.e. no change of profile
26、 is related to the diameter. The rim shall have a 5 tapered bead seat. The specified rim diameter shall be as given in Table 1 5.2.2 Recommendation The flange height should be in the range 13 % to 20 % of the tyre section height.
