11、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, governmental
12、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 Directive
13、s, 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 bodies c
14、asting 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 11900-2 was prepared by Technical Committee ISO/TC 29, Small tools, Subcommittee S
15、C 8, Tools for pressing and moulding. This second edition cancels and replaces the first edition (ISO 11900-2:2001), of which it constitutes a minor revision. In particular, the references given in Clause 2 have been updated, and the indication of surface textures has been updated in accordance with

18、ty 1 Scope This part of ISO 11900 specifies the dimensions and tolerances, in millimetres, of reduced ball-lock punch retainers, type C and type D, for light duty, and of their backing plug, the main use of which is the retention of ball-lock punches in accordance with ISO 10071-1, when punching hol
19、es in steel sheets. It also gives material guidelines and specifies the hardness and designation of ball-lock punch retainers that are in accordance with its specifications. 2 Normative references The following referenced documents are indispensable for the application of this document.
