Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. Interna

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intend

12、ed for its further 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.

18、 milling cutters, of diameters 6 mm to 20 mm for single-flatted shanks, of 25 mm to 63 mm for double-flatted shanks and of 6 mm to 32 mm for shank with inclined clamping surface. In the case of single-flatted shanks, it is applicable to both single-ended cutters and double-ended cutters, as double-f

19、latted shanks cannot admit single-ended cutters.The dimensions of plain cylindrical shanks and threaded shanks are given in ISO 3338-1 and ISO 3338-3, respectively.The two shank types covered by ISO 3338-1 and this part of ISO 3338 have the same dimensional characteristics (diameters and lengths), b
