The work of preparing Internatio
14、nal 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 non-governmental, in liaison with ISO
15、, 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 for voting. Publication as an Inte
16、rnational Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard ISO 10499-2 was prepared by Technical Committee ISO/TC 31, Tyres, rims and valves, Subcommittee SC 7, Industrial tyres and rims. ISO 10499 consists of the following parts, under the gene
17、ral title Industrial tyres and rims Rubber solid tyres (metric series) for pneumatic tyre rims: Part 1: Designation, dimensions and marking; Part 2: Load ratings. Descriptors: Machinery, self-propelled machines, tyres, rubber products, solid tyres, specifications, load capacity, designation, marking

20、 contours fitting these tyres are specified in ISO 3739-3. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this International Standard. At the time of publication, the editions indicated were valid. All standards are s
21、ubject to revision, and parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below.

23、al tyres and rims Rubber solid tyres (metric series) for pneumatic tyre rims Part 1: Designation, dimensions and marking. 3 Definitions For the purposes of this part of ISO 10499, the definitions given in ISO 3877-4, ISO 4223-2 and ISO 5053 apply. 4 Tyre designations 4.1 Dimensional and construction
24、al characteristics See ISO 10499-1. 4.2 Service descriptions The service description shall be indicated as follows: 4.2.1 Load index The load index is a numerical code associated with the maximum load a tyre can carry at the speed indicated by its speed symbol, under the service conditions specified
25、 by the tyre manufacturer. The correlation between load indices and tyre load-carrying capacities shall be as given in Table 1. 4.2.2 Speed symbol The speed symbol shall be as given in Table 2. The speed symbol or speed category indicates the reference speed, defined as the speed at which the tyre c
26、an carry the load corresponding to its load index under the specified service conditions. 5 Marking The marking shall consist of a) the designation of the dimensional and constructional characteristics according to ISO 10499-1; b) the designation of the service description (load index and speed symb
27、ol). The location of the marking of the service description (load index and speed symbol) shall be distinct but in the vicinity of the marking of the dimensional and constructional characteristics. EXAMPLE 225/70 10/6.5 139 A5 The characteristics of a tyre with the above markings are as follows: 6 R
28、eference speed The reference speed for tyre load identification of rubber solid tyres for pneumatic tyre rims shall be 25 km/h, i.e. speed symbol A5. For tyres with a maximum speed below 25 km/h the speed symbol and associated load index shall correspond to the maximum speed of the tyre. 7 Tyre load
29、-carrying capacities 7.1 General 7.1.1 If possible, the reference loads or load indices respectively of rubber solid tyres for pneumatic tyre rims should be adjusted to those of the pneumatic tyres of the same size designation and the highest existing load index number in order to assure equivalence
30、 or interchangeability. NOTEThe additional weight of rubber solid tyres for pneumatic tyre rims is not taken into account when converting industrial vehicles from pneumatic tyres to solid tyres. Load indexSpeed symbol 225:nominal section width equal to 225 mm; 70:nominal aspect ratio equal to 70; 10
31、:nominal rim diameter code, corresponding to 254 mm; 6.5:nominal rim width code; 139:load index (LI) corresponding to a tyre load of 2 430 kg; A5:speed symbol corresponding to a speed category of 25 km/h.
