3、ernational Organization for Standardization) is a worldwide federation of national standards bodies (IS0 member bodies). The work of preparing International Standards is normally carried out through IS0 technical committees. Each member body interested in a subject for which a technical committee ha
4、s been established has the right to be represented on that committee. International organizations, govern- mental and non-governmental, in liaison with ISO, also take part in the work. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnica
5、l standardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an Inter- national Standard requires approval by at least 75% of the member bodies casting a vote. International Standard IS0 10475 was prepared by Tech
6、nical Committee ISO/TC 31, Tyres, rims and valves, Sub-Committee SC 9, Valves for tube and fubeless tyres.

NOTE 1 Terminology used in this International Standard is in accordance with IS0 3877-2:1978, lyres, val

At the time of publi- cation, the editions indicated were valid. All stan- da
11、rds are subject to revision, and parties to agreements based on this International Standard are encouraged to investigate the possibility of ap- plying the most recent editions of the standards in- dicated below. Members of IEC and IS0 maintain registers of currently valid International Standards. I

13、 letters (family code) define a family of valves and are associated with the valve technical characteristics. The first letter corresponds to the valve mouth thread diameter and to the valve shape. It shall be as specified in table 1. The second letter corresponds to the rim hole di- ameter for the
14、appropriate valve. It shall be as specified in table2. EXAMPLES 1 The family code of a straight valve for a tube, the mouth of which has a 5Vl thread and the rim hole a diameter of 8,3 mm, is AB. 2 The family code of a valve for a tube with one bend, the mouth of which has an 8Vl thread and the rim
15、hole a diameter of 14,2 mm, is DH.

16、92(E) 3 The family code of a valve with one bend for a tubeless tyre, the mouth of which has a 12Vl thread and the rim hole a diameter of II,3 mm, is JQ. 3.1.2 The two digits represent the serial number of the valve under consideration in the series of valves of the same family. This serial number i
17、s allocated to each valve, and will be defined in a future Inter- national Standard II. 4 The family code of a sub-assembly with more than three bends, the mouth of which has a 12Vl thread, to be mounted in a valve, is MZ.

21、onds to the component na- ture. It shall be as specified in table3.

22、epresent the serial number of the component considered in the series of com- ponents of the same nature. This serial number is allocated to each component, and will be defined in a future International Standard. 4 General principles 4.1 The four-character code allocated to a valve corresponds to a v
23、alve with cap, core and any other components. The three-character code allocated to components shall appear neither in the designation nor in the marking of a valve. The composition of a complete valve will be defined in a future International Standard, which will also indicate any requirements as t
24、o the use of specific types of cores and cap. 4.2 When two analogous valves are not totally interchangeable, for example because they require rim valve holes with different specifications (even if of the same diameter), the two valves shall be con- sidered different. 4.3 Valves which may be used ind
25、ifferently for tubeless tyres and for tubes shall be identified as valves for tubeless tyres.
