11、dies (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 technical committee has been established has the right to be represented on that committee. International organizatio
12、ns, 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 matters of electrotechnical standardization. The procedures used to develop this document and those intended for its furthe
13、r maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives
14、). 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. Details of any patent rights identified during the development of the document will be in the Intr

This third edition cancels and replaces the second edition (ISO 7388-3:2013), of which it constitutes a minor revision with the following changes: in the title and in all the text, “retention knobs for shanks of form” was changed to “retention knobs of form”; forms AC and
18、UC have been deleted from the title and from the designation (Clause 6); a footnote was added to Tables 1 and 5. ISO 7388 consists of the following parts, under the general title Tool shanks with 7 /24 taper for automatic tool changers: Part 1: Dimensions and designation of shanks of forms A, AD, AF
