The work of p

16、reparing 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,

17、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 Directives, Part 3. The main ta

18、sk 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. Attenti

19、on is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 14303 was prepared by Technical Committee ISO/TC 20, Aircraft and space vehicles, Subcommi

BSISO14303:2002ivIS:30341 O2002(E) I SO 2002 All irthgs ersedevr vIntroduction ISO 14303 together with ISO 15863 and ISO 17401 forms a set of International Standards that describes fully

21、 the process for communicating information about launch vehicle (LV) to spacecraft (SC) interfaces. Clauses 4 to 8 of this International Standard identify the parameters of an LVSC interface, while clauses 9 and 10 define the methodology for verification of the interface by analyses, testing or both

22、. Clause 11 defines the operations performed on the SC to prepare it for launch and the joint operations performed until it is installed on the LV. Some sections of this document may refer to elements of the LV or SC, or elements of both, that are not applicable to their design characteristics. Thes

23、e sections should therefore only be considered if applicable. The annexes give examples of the typical presentation format of the various interface parameters, as appropriate.

24、craft interfaces 1 Scope This International Standard specifies the interfaces between a launch vehicle (LV) and the spacecraft (SC) being launched, to provide LV and SC organizations with the necessary format for presenting the required technical data on existing and future interfaces. Its intended

25、purpose is to minimize costs and reduce the risks from errors resulting from miscommunication. It does not limit the ability of LV or SC organizations to specify unique requirements. 2 Terms and definitions For the purposes of this International Standard, the following terms and definitions apply. 2
