10、rs 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

11、a 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 matt

12、ers 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 circul

13、ated 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 responsib

14、le for identifying any or all such patent rights. ISO 2380-1 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 2380-1:1997), which has been technicall

15、y revised. ISO 2380 consists of the following parts, under the general title Assembly tools for screws and nuts Screwdrivers for slotted-head screws: Part 1: Tips for hand- and machine-operated screwdrivers Part 2: General requirements, lengths of blades and marking of hand-operated screwdrivers ISO

16、 2380-1:2004 (E) 2 1 Scope This part of ISO 2380 specifies the shape/form, dimensions and designation of the tips of hand- and machine-operated screwdrivers for slotted-head screws. It also gives the technical specifications and test conditions for the screw-drivers and, in the case of hand-operated

17、 screwdrivers, specifies the test torque which the blade-to-handle connection shall withstand. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest ed

18、ition of the referenced document (including any amendments) applies.

27、m hardness of 56 HRC along their full length. 5.2 Test conditions for the blades or bits When tested with the minimum test torques M and M1, expressed in newton metres, in accordance with Tables 1 and 2, the screwdriver blades or bits shall not show any cracks or breaks or any permanent deformations

28、 which could influence their usability. NOTE The minimum test torques have been calculated using the following formulae: 2M ba= and M1= 1,12 ba2 where a is the nominal thickness of the tip, expressed in millimetres; b is the nominal width of the tip, expressed in millimetres. A torque testing device

29、 shall be used which sustains the test specimen against ejecting forces and prevents the occurrence of bending moments, and the test disc used shall be according to Figure 3 or Figure 4, have a hardness of at least 64 HRC and be of such strength that no deformation can occur during testing. The test
