18、 - Document requirements for pyrotechnic subsystem. 32 EN 14607-6:2004 (E) 4 Foreword This document (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 Febr
19、uary 2005, and conflicting national standards shall be withdrawn at the latest by February 2005. It is based on a previous version1) originally prepared by the ECSS Mechanical Engineering Standard Working Group, reviewed by the ECSS Technical Panel and approved by the ECSS Steering Board. The Europe
20、an Cooperation for Space Standardization (ECSS) is a cooperative effort of the European Space Agency, 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 applie
21、d together for the management, engineering and product assurance in space projects and applications. 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 structure
22、s and methods to be applied where they are effective, and for the structures and methods to evolve as necessary without rewriting the standards. EN 14607 Space engineering - Mechanical is published in 8 Parts: Part 1: Thermal control Part 2: Structural Part 3: Mechanisms Part 4: ECLS Part 5: Propuls
23、ion Part 5.1: Liquid and electric propulsion for spacecraft Part 5.2: Solid propulsion for spacecraft, solid and liquid propulsion for launchers Part 6: Pyrotechnics Part 7: Mechanical parts Part 8: Materials According to the CEN/CENELEC Internal Regulations, the national standards organizations of
24、the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spai

This part defines the standards to be applied for the use of pyrotechnics on all sp
26、acecraft and other space products including launch vehicles. It addresses the aspects of design, 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 requir
27、ed confidence can only be established indirectly by the testing of identical items. Test results 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 technica
28、l aspects. The failure or unintentional operation of a pyrotechnic item can be catastrophic for the 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 i
29、n the manner of a subsystem. When viewed from the perspective of a specific project context, the 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 requirem
30、ents of specifications, standards and related documents are evaluated, and made applicable to a specific 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
