6、on 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 subject for which a technical committee has been established ha
7、s 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) on all matters of electrotechnical standardization. Inte
8、rnational 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 committees are circulated to the member bodies for voting. Publica
9、tion 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 held responsible for identifying any or all such patent rig
10、hts. ISO 11900-1 was prepared by Technical Committee ISO/TC 29, Small tools, Subcommittee SC 8, Tools for pressing and moulding. This second edition cancels and replaces the first edition (ISO 11900-1:1994), of which it constitutes a minor revision. In particular, the references given in Clause 2 ha
11、ve been updated, and the indication of surface textures has been updated in accordance with ISO 1302:2002. ISO 11900 consists of the following parts, under the general title Tools for pressing Ball-lock punch retainers: Part 1: Types A and B, rectangular and square for light duty Part 2: Types C and
12、 D, reduced for light duty Part 3: Type E, reduced for heavy duty BS ISO 11900-1:2007blank1Tools for pressing Ball-lock punch retainers Part 1: Types A and B, rectangular and square for light duty 1 Scope This part of ISO 11900 specifies the dimensions and tolerances, in millimetres, of ball-lock pu
13、nch retainers, type A (rectangular) and type B (square), for light duty, and of their backing plates. The main use of ball-lock punch retainers and their backing plates is the retention of ball-lock punches, in accordance with ISO 10071-1, when punching holes in steel sheets. It gives material guide
14、lines and hardness requirements, and specifies the designation of ball-lock punch retainers in accordance with this part of ISO 11900. 2 Normative references The following referenced documents are indispensable for the application of this document.
