12、mber 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 organizations, governme
13、ntal 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. International Standards are drafted in accordance with the rules given in the ISO/IEC Dire
14、ctives, 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 bod
15、ies 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 responsible for identifying any or all such patent rights. ISO 10071-1 was prepared by Technical Committee ISO/TC 29, Small tools, Subcommit
16、tee SC 8, Tools for pressing and moulding. This second edition cancels and replaces the first edition (ISO 10071-1:2001), of which it constitutes a minor revision. In particular, the normative references given in Clause 2 have been updated, and the indication of surface textures has been made in acc
17、ordance with ISO 1302:2002. ISO 10071 consists of the following parts, under the general title Tools for pressing Ball-lock punches: Part 1: Ball-lock punches for light duty Part 2: Ball-lock punches for heavy duty BS ISO 10071-1:2008INTERNATIONAL STANDARD ISO 10071-1:2008(E) ISO 2008 All rights res
18、erved 1Tools for pressing Ball-lock punches Part 1: Ball-lock punches for light duty 1 Scope This part of ISO 10071 specifies interchangeability dimensions and tolerances, in millimetres, for ball-lock punches for light duty. It is applicable to ball-lock punches with shank diameter sizes from 6 mm
19、up to and including 32 mm, in round, square, rectangular and oblong shapes, for punching holes in steel sheets or other materials, the thickness of which is less than 3 mm. This part of ISO 10071 also gives examples related to materials and hardness, and specifies the designation of ball-lock punche
20、s for light duty. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies.
