The work of preparing International Standards is normally carried out through ISO technical

19、 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, also take part in the work. ISO collaborates closely with

20、 the International 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 3. Draft International Standards adopted by the technical committees are circulated to the m

21、ember 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 International Standard may be the subject of patent rights. ISO shall not be held responsi

22、ble for identifying any or all such patent rights. International Standard ISO 15974 was prepared by Technical Committee ISO/TC 2, Fasteners.

24、with nominal diameters from 3,2 mm up to and including 4,8 mm. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this International Standard. For dated references, subsequent amendments to, or revisions of, any

25、 of these publications do not apply. However, parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For undated references, the latest edition of the normative document

Nonconformance to the values in Table 2 may result in assembly difficulties and/or reduction in the shear and tensile loads specified in Table 3. If necessary, to facilitate alignment, only the component on the access side may have a
