The work of pre
9、paring 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 and non-governmental, in
10、 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 Directives, Part 2. The main task
11、 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 casting a vote. Attention
12、 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 6519 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 7, Injection equipment
13、and filters for use on road vehicles. This third edition cancels and replaces the second edition (ISO 6519:1993), which has been technically revised by the addition of nominal diameter 40 and dimensions for nominal diameter types 25 and 35.

16、ternational Standard specifies the dimensions, necessary for interchangeability, of tapers for the shaft ends and hubs of fuel injection pumps on diesel (compression-ignition) engines. The shaft ends and hubs specified can be used either with or without woodruff keys, and for other applications for

18、ith taper Shaft ends shall be as shown in Figure 1 and in accordance with Table 1. The shaft ends may be made optionally according to Type 1 or 2. However, it shall be possible to screw the Go gauge for the thread up to the XX line. 2.3 Keyways of hub with taper Hub keyways shall be as shown in Figu
19、re 2 and in accordance with Table 2. The length of the hub cone shall be such that, after assembling, the face at the smaller diameter of the hub cone lies far enough in front of the XX line (see Figures 1 and 2) that the fixing nut can be correctly screwed to this line.
