The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established
21、 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 Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. I
22、nternational Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part3. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least75% of the m
23、ember bodies casting a vote. International Standard ISO15480was prepared by Technical Committee ISO/TC2, Fasteners.iv blankENISO15480:1999 BSI 04-2000 1 1 Scope This International Standard specifies the characteristics of hexagon washer head drilling screws with tapping screw threads from ST2,9up to
24、 and including ST6,3. 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 of these publications do not apply. Howe
