It supersedes BS AU50-4-5.2:1996 which is withdrawn.

The work of preparing International Standards is normally carried out through ISO technical committees. Each m
7、ember 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 non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International
8、Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards a
9、dopted 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 member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of p
10、atent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 3739-3 was prepared by Technical Committee ISO/TC 31, Tyres, rims and valves, Subcommittee SC 7, Industrial tyres and rims. This second edition cancels and replaces the first edition (ISO 3739-3:1995),
11、 which has been technically revised. ISO 3739 consists of the following parts, under the general title Industrial tyres and rims: Part 1: Pneumatic tyres (metric series) on 5 tapered or flat base rims Designation, dimensions and marking Part 2: Pneumatic tyres (metric series) on 5 tapered or flat ba
12、se rims Load ratings Part 3: Rims BS ISO 3739-3:20081Industrial tyres and rims Part 3: Rims 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 an
13、d for solid tyres for pneumatic tyre rims, primarily intended for industrial vehicles for use on prepared surfaces. ISO 3739-1 gives the designation, dimensions and marking, and ISO 3739-2 gives the load ratings, of pneumatic tyres (metric series). ISO 10499-1 covers the designation, dimensions and
14、marking of rubber solid tyres (metric series) for pneumatic tyre rims. Rim dimensions are specified for size and contour only. The tyre and wheel/rim manufacturers are consulted for confirmation of the suitability of the tyre/rim combinations, particularly with regard to rim profile and wheel streng

17、les As far as possible, rims shown in Tables 1 and 2 should be used for the metric series of tyres; only if absolutely necessary should new profiles be considered. All rim profiles shall be independent from the rim diameter, i.e. no change of profile shall be related to the diameter. BS ISO 3739-3:2
