6、dies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental an
7、d non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives,
8、 Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies cas
9、ting 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 for identifying any or all such patent rights. ISO 5415 was prepared by Technical Committee ISO/TC 29, Small tools, Subcommittee SC 2,
10、High speed steel cutting tools and their attachments. This second edition cancels and replaces the first edition (ISO 5415:1977), which has been technically revised. BS ISO 5415:2007blank1Reduction sleeves with 7/24 external and Morse internal taper and incorporated screw 1 Scope This International
11、Standard specifies the dimensions of reduction sleeves with 7/24 external taper No. 30-40-45-50 and 60 and Morse internal taper No. 1 to 6 (Morse taper No. 4, 5 and 6 being either with positive drive, see Figure 2, or without positive drive, see Figure 1). These sleeves permit driving of tools with
12、Morse taper shanks with tapped holes with the aid of an internal screw. The form of this screw and its fixation in the sleeve are left to the manufacturers discretion. 7/24 tapers are in accordance with ISO 297. Morse tapers are in accordance with ISO 296 and ISO 5413. 2 Normative references The fol
