19、ternational 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 h

20、as 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. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical

21、 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 requires approval by

22、at least 75 Oh of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this part of IS0 7093 may be the subject of patent rights. IS0 shall not be held responsible for identifying any or all such patent rights. International Standard IS0 7093-1 was pre

25、ameters) ranging from 3 mm to 36 mm inclusive. Washers conforming to this part of IS0 7093 are intended for use in cases where soft material pieces are to be clamped or where there are large clearance holes in the workpiece. Nevertheless, in the latter case, the suitability of the washer thickness s

26、hould be checked. Washers of hardness class 200 HV are suitable for - hexagon bolts and screws of product grades A and B in property classes up to and including 8.8; - hexagon nuts of product grades A and B in property classes up to and including 8; - hexagon bolts, screws and nuts of stainless stee

27、l of similar chemical composition; - case-hardened thread rolling screws.
