11、rights reserved 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 subje
12、ct for which 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
13、) on all matters 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 committe
14、es are circulated 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 h
15、eld responsible for identifying any or all such patent rights. ISO 15488 was prepared by Technical Committee ISO/TC 29, Small tools. This second edition cancels and replaces the first edition (ISO 15488:1996), which has been technically revised. In particular, in Table 3, the values of d10 for nomin
16、al dimensions 25 mm and 32 mm as well, as the values of l10 for nominal values 25 mm, 32 mm and 40 mm, have been modified. Figure 5 has been modified for the sake of clarity.

18、national Standard specifies the dimensions, materials and manufacturing requirements, and designation of collets (of form A or of form B) for tools with cylindrical shanks and their corresponding holders and nuts. For non-standardized clamping devices, such as clamping devices specified in drawings,
19、 these holders can be agreed upon between customer and supplier. Form A applies to milling and any other application where a hard collet bore is required, provided that the clamping range of h10 be sufficient. Form B applies for general purposes where an extended clamping range is required. 2 Normat

For the test mandrel, the following specifications apply: a) diameter tolerance: h6; b) cylindricity: 0,002 mm; c) parallelism: 0,002 mm; d) roundness: 0,002 mm; e) surface without longitudinal marks; f) maximum surface roughness Rz = 4 m; g) surface hardness: (58 3 0 + ) HRC.
