The work of preparing International S
14、tandards is normally carried out through ISO technical 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, als
15、o take part in the work. ISO collaborates closely with 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 2. The main task of technical committe
16、es is to prepare International Standards. 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 least 75 % of the member bodies casting a vote. Attention is drawn to the possi
17、bility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 8992 was prepared by Technical Committee ISO/TC 2, Fasteners, Subcommittee SC 7, Reference standards for fasteners (mainly cover
18、ing terminology, dimensioning, sizes and tolerancing). This second edition cancels and replaces the first edition (ISO 8992:1986), which has been technically revised.

40、ailing clients of the SABS .ISO 8992:2005(E) 4 ISO 2005 All rights reserved4 General requirements Standardized bolts, screws, studs and nuts are defined by the following elements: a) mechanical properties (property class, material); b) product grade (tolerances); c) standardized geometrical features
41、 (if any); d) surface coatings (if required); e) special requirements (if agreed). All information relates to fully manufactured products. Specific manufacturing processes are not required, except where they have been laid down in the individual standards or have been agreed between customer and sup
42、plier. The product shall have intact surfaces and edges and shall be free of burrs consistent with the manufacturing methods used. It is not generally required that small burrs due to operations such as slotting, or resulting from forging, pressing or trimming, be removed. Any burr which influences
43、the performance of the product or would be a safety hazard when handled, however, shall be removed. Trimming burrs beyond the bearing face of bolts and screws is not permissible. Centre holes for bolts and screws are permissible, unless otherwise specified. Unless a surface coating is agreed, the su
44、rface finish of the products shall be as processed for steel products, or plain for products made of stainless steel or non-ferrous metal. Bolts, screws, studs and nuts shall be delivered in a clean condition and lightly oiled, if no other conditions have been agreed.
