20、(EN 14607-6:2004) has been prepared by CMC. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by February 2005, and conflicting national standards shall be withdrawn at the latest by February 2005. It

21、is based on a previous version 1 ) originally prepared by the ECSS Mechanical Engineering Standard Working Group, reviewed by the ECSS Technical Panel and approved by the ECSS Steering Board. The European Cooperation for Space Standardization (ECSS) is a cooperative effort of the European Space Agen

22、cy, National Space Agencies and European industry associations for the purpose of developing and maintaining common standards. This document is one of the series of space standards intended to be applied together for the management, engineering and product assurance in space projects and application

23、s. Requirements in this document are defined in terms of what shall be accomplished, rather than in terms of how to organize and perform the necessary work. This allows existing organizational structures and methods to be applied where they are effective, and for the structures and methods to evolve

24、 as necessary without rewriting the standards.

27、14607 Part 6 of Space engineering - Mechanical defines the requirements for the discipline of pyrotechnics engineering. This part defines the standards to be applied for the use of pyrotechnics on all spacecraft and other space products including launch vehicles. It addresses the aspects of design,

28、analysis, verification, manufacturing, operations and safety. As any pyrotechnic item used for flight can function only once, it can never be fully tested before its crucial mission operation. The required confidence can only be established indirectly by the testing of identical items. Test results

29、and theoretical justification are essential for demonstration of fulfilment of the requirements. The requirement for repeatability shows that product assurance plays a crucial role in support of technical aspects. The failure or unintentional operation of a pyrotechnic item can be catastrophic for t

30、he whole mission and life threatening. Specific requirements can exist for the items associated with it. As all pyrotechnic functions are to be treated similarly, collective control needs to be applied in the manner of a subsystem. When viewed from the perspective of a specific project context, the

31、requirements defined in this document should be tailored to match the genuine requirements of a particular profile and circumstances of a project. NOTE Tailoring is a process by which individual requirements of specifications, standards and related documents are evaluated, and made applicable to a s

32、pecific project by selection, and in some exceptional cases, modification of existing or addition of new requirements. 2 Normative references The following referenced documents are indispensable for the application of this document.
