This standard (EN 16603-32-02:2014) originates from ECSS-E-ST-32-02C Rev. 1. This European Stan

24、dard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by February 2015, and conflicting national standards shall be withdrawn at the latest by February 2015. Attention is drawn to the possibility that some of the elements o

25、f this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document has been developed to cover specifically space systems and has therefore precedence over any EN covering the same scope but with a wider

26、domain of applicability (e.g. : aerospace). According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former

28、E) 6 1 Scope This Standard defines the structural design verification of metallic and non-metallic pressurized hardware which includes pressure vessels, pressurized structures, pressure components (such as valves, pumps, lines, fittings, and hoses), and special pressurized equipment (e.g. batteries,

29、 heat pipes, cryostats, sealed containers, hazardous fluids container). External supports and structural interfaces of pressurized hardware are not covered by this standard. Solid propellant motor cases are not covered by this standard. Objectives of the associated verification process are primarily

30、 to demonstrate the qualification of design and performance, as meeting all specified requirements, and to ensure that the flight hardware is free from workmanship defects and acceptable for flight. This Standard applies to all space products and in particular to launch vehicles, transfer vehicles,

31、re-entry vehicles, spacecraft, space station, landing probes and rovers, sounding rockets, payloads and instruments. This standard may be tailored for the specific characteristics and constraints of a space project in conformance with ECSS-S-ST-00. BS EN 16603-32-02:2014EN 16603-32-02:2014 (E) 7 2 N
