20、ord ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a techni
21、cal 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 Electrotechnical Commission (IEC) on all matters of e
22、lectrotechnical 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 member bodies for voting. Publication as an International Standard requir
23、es approval by at least 75% of the member bodies casting a vote. International Standard ISO 10669 was prepared by Technical Committee ISO/TC 2, Fasteners.iv blankENISO10669:1999 BSI 03-2000 1 1 Scope This International Standard specifies the characteristics of plain steel washers of product grade A
