6、ck coverBS3087-13:1991 ii BSI 10-1999 National foreword This Part of BS3087 has been prepared under the direction of the Machine, Engineers and Hand Tools Standards Policy Committee. It is identical with ISO9243:1988 “Pliers and nippers Carpenters pincers Dimensions and test values”, published by th
7、e International Organization for Standardization (ISO). As work continues in ISO the number of tools covered by this standard will increase. BS3087-10 covers those tools in BS3087:1959 (withdrawn) that were not standardized by ISO because their style and application were exclusive to the UK. The Tec
8、hnical Committee has reviewed the provisions of ISO5744, to which reference is made in the text, and has decided that they are acceptable for use in conjunction with this standard. A related British Standard to ISO5744:1988 is BS3087-4:1988. It is recommended that pliers, pincers and nippers should
9、be legibly and indelibly marked with a name, trademark or the manufacturing code that will allow traceability. BS3087-13 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 a contract. Users of British S
10、tandards 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 cover and a back cover. This s
11、tandard 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.

12、general requirements (Identical) 1) Marking BS3087-13:1991 on or in relation to a product represents a manufacturers declaration of conformity, 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 r
13、esponsibility of the person making the claim. Such a declaration is not to be confused with third party certification of conformity, which may also be desirable.BS3087-13:1991 BSI 10-1999 1 1 Scope This International Standard specifies the principle dimensions of carpenters pincers and the test valu
14、es in order to verify their aptitude to function in conformity with ISO5744. It also specifies the minimum hardness of the cutting edge. The general technical requirements are given in ISO5743. The carpenters pincers illustrated in this International Standard are examples only and are not intended t
15、o affect the manufacturers design. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this International Standard. At the time of publication, the editions indicated were valid. All standards are subject to revision, and
16、parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the standards listed below.
