8、l Organization 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 es
9、tablished has 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 standardi
10、zation. International 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 vot
11、ing. Publication 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 suc

ISO 22010:2007(E) ISO 2007 All rights reserved v Introduction This International Standard establishes the minimum requirements for providing adequa
13、te control of the mass properties of space systems to meet mission requirements. In addition, many recommended practices that add value to the mass properties monitoring tasks are presented. Throughout this International Standard, the minimum essential criteria are identified by the use of the key w
14、ord “shall.” Recommended criteria are identified by the use of the key word “should,” and while not mandatory, are considered to be of primary importance in providing timely and accurate mass properties support for contracts. It is advisable that deviations from the recommended criteria only occur a
15、fter careful consideration and thorough evaluation have shown alternative methods to be satisfactory. The requirements can be tailored for each specific space programme application. INTERNATIONAL STANDARD ISO 22010:2007(E) ISO 2007 All rights reserved 1 Space systems Mass properties control 1 Scope
16、This International Standard describes a process for managing, controlling and monitoring the mass properties of space systems. The relationship between this management plan and the performance parameters for mass properties to be met throughout the mission is described. Ground handling, dynamics ana
17、lysis and test set- ups that rely on accurate mass properties inputs are identified. This International Standard covers all programme phases from pre-proposal through to end of life. 2 Normative references The following referenced documents are indispensable for the application of this document.
