The IEEE develops its standards through a consensus develop-ment process, approved by the American National Standards Institute, which brings together volunteers representing variedviewpoints and interests to achieve the nal product. Volunteers are not necessarily members of the Institute and se
7、rve with-out compensation. While the IEEE administers the process and establishes rules to promote fairness in the consensus devel-opment process, the IEEE does not independently evaluate, test, or verify the accuracy of any of the information containedin its standards.Use of an IEEE Standard is who

IEEE Standards documents are supplied “AS IS.”The existence of an IEEE Standard does not imply that there are no other ways to produce, test, measure, purchase, market,or provide other goods and services related to the scope of the IEEE Standard. Furthermore, the viewpoint expresse
11、d at thetime a standard is approved and issued is subject to change brought about through developments in the state of the art andcomments received from users of the standard. Every IEEE Standard is subjected to review at least every ve years for revi-sion or reafrmation. When a document is more tha
12、n ve years old and has not been reafrmed, it is reasonable to concludethat its contents, although still of some value, do not wholly reect the present state of the art. Users are cautioned to checkto determine that they have the latest edition of any IEEE Standard.In publishing and making this docum

When the need for interpretations is brought
15、to the attention of IEEE, the Institute will initiate action to prepareappropriate responses. Since IEEE Standards represent a consensus of concerned interests, it is important to ensure that anyinterpretation has also received the concurrence of a balance of interests. For this reason, IEEE and the
16、 members of its soci-eties and Standards Coordinating Committees are not able to provide an instant response to interpretation requests except inthose cases where the matter has previously received formal consideration. Comments for revision of IEEE Standards are welcome from any interested party, r

Overview1.1 ScopeThis standard covers zinc-coated steel lag screws of the fetter drive, gimlet point, and twist drive typescommonly used in overhead line construction. 1.2 ApplicationThe lag screws conforming to this standard shall, in all respects, meet the basic dimens
32、ional and performancerequirements hereinafter stated. The text, specifications or standards references, and associated Figure 1through Figure 5 supplement each other and shall be considered as parts of this standard. Metric lag screws are not covered by this standard.2. ReferencesThe following stand
33、ards shall be used in conjunction with this standard. When the following standards aresuperceded by an approved revision, the revision shall apply.ANSI B18.2.1-1996, American National Standard for Square and Hex Bolts and Screws1ASTM A153/A153M-98, Standard Specication for Zinc-Coating on Iron and S
