8、Part of BS3087 has been prepared under the direction of the Machine, Engineers and Hand Tools Standards Policy Committee and forms one of a number of British Standards which relate to a wide variety of hand tools. Parts1 to10 of this British Standard supersede BS3087:1959 which is withdrawn. It is r
9、ecommended that pliers should be legibly and indelibly marked with a name, trademark or the manufacturing code that will allow traceability. BS3087-10 1)should be marked either on the tool or on its associated packaging. A British Standard does not purport to include all the necessary provisions of
10、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, pagesi andii, pages1 to4, an inside back
11、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. 1) Marking BS3087-10:1991 on or in relation to a product represents a manufacturers declaration of conformity
12、, i.e.a claim by or on behalf of the manufacturer that the product meets the requirements of the standard. The accuracy of the claim is therefore solely the responsibility of the person making the claim. Such a declaration is not to be confused with third party certification of conformity, which may
13、 also be desirable.BS3087-10:1991 BSI 10-1999 1 1 Scope This Part of BS3087 specifies the dimensions of pliers which are not standardized by the International Organization for Standardization (ISO) because their style and application are exclusive to the United Kingdom. The tools covered in this Par
14、t are of the following types: fencing pliers; pipe grip gas pliers; duckbill pliers. NOTEThe title of the publication referred to in this standard is given on the inside back cover. 2 Fencing pliers 2.1 Dimensions The dimensions of fencing pliers shall comply with those given inTable 1 andFigure 1.
15、2.2 Maximum permissible permanent set Fencing pliers shall comply with the maximum permissible permanent set given inTable 1 after application of the load test.

21、th BS3087-4. After the load test, the permanent set shall not exceed the value given inTable 3. If the distance L 1is not suitable for the load test, the load F applied at a distance L 1shall be calculated from the following equation: where F is the load given inTable 1; L 1 is the distance from the
22、 centre of the joint rivet to the applied load given inTable 1; L 1 is the measured distance from the centre of the joint rivet to the applied load F. where F is the load given inTable 2; L 1 is the distance from the centre of the joint rivet to the applied load given inTable 2; L 1 is the measured
