18、ational 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 technical committee has b
19、een 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 electrotechnical sta
20、ndardization. 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 requires approval by at l
21、east 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 responsible for identifying any or all such patent rights. International Standard ISO 7094 was prep
22、ared by Technical Committee ISO/TC 2, Fasteners. This second edition cancels and replaces the first edition (ISO 7094:1983), which has been technically revised.

23、tional Standard specifies the characteristics of extra-large-series, product-grade-C plain washers in the 100 HV hardness class, of nominal sizes (nominal thread diameters) ranging from 5 mm to 36 mm inclusive. These washers are suitable for hexagon bolts and screws of product grade C in property cl
24、asses up to and including 6.8, and hexagon nuts of product grade C in property classes up to and including 6 used in timber structures. If dimensions other than those listed in this International Standard are required, they should be selected from those given in ISO 887. 2 Normative references The f
