In this standard account has been taken of the current International Organization for Standard
10、ization (ISO) agreements on sizes and tolerances whilst due account has been taken of current production trends in British industry. Metric units of measurement are used throughout this standard for all dimensions and tolerances excluding the designating and nominal sizes of unified wrenches. Tolera
11、nces on combination wrenches in this standard are taken from ISO691. The shapes of combination wrenches given inFigure 1 are representative only. For guidance purposes notes on the safe usage of combination wrenches are given inAnnex B. A British Standard does not purport to include all the necessar
12、y provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pages i and ii, pages1 to
13、 12, an inside back cover and a back cover. This standard has been updated (see copyright date) and may have had amendments incorporated. This will be indicated in the amendment table on the inside front cover.BS7586:1992 BSI 12-1999 1 1 Scope This British Standard specifies dimensions, testing, and
14、 other requirements for combination wrenches in the following series: 2 References 2.1 Normative references This British Standard incorporates, by reference, provisions from specific editions of other publications. These normative references are cited at the appropriate points in the text and the pu
15、blications are listed on the inside back cover. Subsequent amendments to, or revisions of, any of these publications apply to this British Standard only when incorporated in it by updating or revision. 2.2 Informative references This British Standard refers to other publications that provide informa
16、tion or guidance. Editions of these publications current at the time of issue of this standard are listed on the inside back cover, but reference should be made to the latest editions. 3 Definition For the purposes of this British Standard the following definition applies. combination wrench a shank
