BSISO16915:2003 iii Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards b
11、odies (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 organizati
12、ons, 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 in the
13、 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 % of t
14、he 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 16915 was prepared by Technical Committee ISO/TC 29, Small tools
15、, Subcommittee SC 8, Tools for pressing and moulding. BSISO16915:2003. vi 1 Tools for moulding Sprue pullers 1S c o p e This International Standard specifies the main dimensions and tolerances, in millimetres, of sprue pullers, which are used mainly in injection moulds for plastics and rubbers. See
16、the example of application in Figure 1. It also specifies the material, hardness and designation of sprue pullers conforming to this International Standard. 2 Normative references The following referenced documents are indispensable for the application of this document.
