18、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 has the right to be represented
19、 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. International Standards are draft
20、ed 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. Publication as an International Stan
21、dard 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 rights. ISO 15864 was prepared b

BSISO15864:2004 vIntroduction Throughout this International Standard, the minimum essential criteria are identified by the use of the key word “shall”. Recommended criteria are identified
23、by the use of the key word “should”, and while not mandatory are considered to be of primary importance in providing serviceable, economical and practical designs. Deviations from the recommended criteria should occur only after careful consideration, extensive testing and thorough service evaluatio

25、levels for applicable unmanned spacecraft programmes. It also provides the requirements for documentation associated with testing activities. The acceptance criteria, specifications or procedures, and other detail test requirements applicable to a particular programme are defined in the applicable t
26、echnical specifications and statement of work. When requirements have to be verified by measuring product performance and function under various simulated environments, the method is referred to as “Test”. The requirements of this International Standard may be tailored for each specific space progra

37、osophy In principle, testing is one verification method that ensures that the spacecraft meets all design, performance and product assurance requirements. This International Standard contains provisions for qualification and acceptance testing, or proto-flight testing (PFT). It assumes that hardware
38、 development is complete. Performance requirements contained in the contract documentation are compared to performance achieved during testing and provide the basis for judging the capability of the spacecraft to operate as intended. Besides verifying performance, test programmes provide the followi
39、ng items: a) training for personnel in the operation of the spacecraft; b) incorporation of corrective actions taken for nonconformances; c) validation of data processing; d) opportunity to perform calibrations under simulated space conditions; e) verification of ground hardware compatibility with t
40、he spacecraft for operations. Factors that contribute to the provisions of test specifications include experience with similar spacecraft, subsystem and unit; cost considerations; and reliability requirements. This International Standard contains range conditions to which the items under test shall
41、be operated and test conditions that shall be used to demonstrate capability. 4.2 Tailoring of requirements The test requirements may be tailored to fulfill the objectives of individual tests. Tailoring parameters shall be determined by negotiations among the customer, spacecraft manufacturer and la
42、unch service provider. 4.3 Development tests Development tests support design feasibility and assist in evolution of design. Development tests are necessary to validate new design concepts and the application of proven concepts and techniques to a new configuration. Development tests are used to con
43、firm structural and performance margins, manufacturability, test simplification, maintainability, reliability, lifetime prediction and compatibility with safety. Therefore, requirements for development testing depend on the maturity of the design used and the operational requirements of the specific
44、 project. By its nature, development testing cannot be reduced to a standardized set of procedures. Where practicable, development tests shall be conducted over a range of operating conditions that exceed design limits to identify marginal design features. Development tests may be conducted on mock-
45、ups, breadboards, development models or integration models. BSISO15864:20044 4.4 Qualification tests Qualification tests demonstrate that items meet design requirements and include proper margin. The qualification test level shall exceed the maximum predicted levels by a factor of safety or qualific
46、ation margin; unless otherwise specified, the qualification test duration shall be longer than maximum environment duration with appropriate qualification margin. In addition, qualification tests shall validate methods, procedures, facility conditions and ground support test equipment that will be r
47、eused for acceptance. 4.5 Acceptance tests Acceptance tests shall demonstrate that the item is free of workmanship defects and integration errors and that its function and performance to the extent practicable can meet stipulated mission requirements. Acceptance tests detect latent material or workm
48、anship defects introduced during the manufacturing and assembly process by measuring function and performance parameters. Such parameters shall be measured through sequential tests to identify function and performance degradation that is likely to damage mission purposes and to establish a baseline
49、to ensure that no degradation is found in the data history. 4.6 Proto-flight tests It shall be recognized that the proto-flight approach presents a higher risk than the approach in which design margins are demonstrated by the testing of a dedicated nonflight qualification item. Moreover, programmatic realities of limited production, tight schedules, and budgetary limits do not always allow the use of dedicated nonflight qualification items. In response, s
