10、rds bodies (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 organ
11、izations, 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. International Standards are drafted in accordance with the rules given i
12、n the ISO/IEC Directives, 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 %
13、 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 held responsible for identifying any or all such patent rights. ISO 10071-2 was prepared by Technical Committee ISO/TC 29, Smal

This first edition of ISO 10071-2, together with ISO 10071-1:2001, cancels and replaces ISO 10071:1991, of which it constitutes a technical revision. ISO 10071 consists of the following parts, under the general title Tools for pressing Bal

16、or ball-lock punches for heavy duty. It is applicable to ball-lock punches with shank diameter sizes from 10 mm up to including 40 mm, in round, square, rectangular and oblong shapes, for punching holes in steel sheets or other materials the thickness of which is less than 8 mm. This part of ISO 100
17、71 also gives examples related to materials and hardness, and specifies the designation of ball-lock punches for heavy duty. 2 Normative references The following referenced documents are indispensable for the application of this document.
