13、 Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a
14、technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matter
15、s 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 committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulat
16、ed 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 possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible
17、 for identifying any or all such patent rights. ISO 5746 was prepared by Technical Committee ISO/TC 29, Small tools, Subcommittee SC 10, Assembly tools for screws and nuts, pliers and nippers. This third edition cancels and replaces the second edition (ISO 5746:1988) which has been technically revis

19、neers and “Linemans” pliers Dimensions and test values 1 Scope This International Standard specifies the principal dimensions of engineers and Linemans pliers and the test values for the pliers in order to verify their aptitude to function in conformity with ISO 5744. General technical requirements
20、are given in ISO 5743. The engineers and Linemans pliers illustrated in this International Standard are examples only and are not intended to affect the manufacturers design. 2 Normative references The following referenced documents are indispensable for the application of this document.

22、s pliers The main dimensions of engineers pliers are shown in Figure 1 and given in Table 1. Engineers pliers can be made with or without a joint cutter, at the manufacturers discretion. Engineers pliers shall be tested in accordance with ISO 5744. After the load test, the permanent set s shall not
23、exceed the value given in Table 2. If distance l1 is not suitable for the load test, the formula given in ISO 5744:2004, 4.2 shall be used. The cutting force, F1, and the diameter, d, of the test wire shall not exceed the values given in Table 2. Pliers having a lever ratio differing from the values
24、 given in Table 2 shall be checked for compliance using the formula given in ISO 5744:2004, 5.3.2.
