35、N 16602-40:2018) has been prepared by Technical Committee CEN/CLC/JTC 5 “Space”, the secretariat of which is held by DIN (Germany). This document (EN 16602-40:2018) originates from ECSS-Q-ST-40C Rev.1. This European Standard shall be given the status of a national standard, either by publication of

36、an identical text or by endorsement, at the latest by October 2018, and conflicting national standards shall be withdrawn at the latest by October 2018. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not

37、be held responsible for identifying any or all such patent rights. This document supersedes EN ISO 14620-1:2002. The main changes with respect to EN ISO 14620-1:2002 are listed below: new EN number, Complete and thorough review with the focus on simplification and streamlining to improve clarity and

38、 consistency of requirements. Applicability guidelines to the different space systems has been defined (see applicability matrix provided in Annex E). System safety programme requirements reworked, i.e. the system safety programme supports the risk management process described in EN 16601-80 (based

39、on ECSS-M-ST-80C). Space debris mitigation streamlined. Atmospheric re-entry addressed. Safety design principles reworked. Safety risk reduction and control updated. Safety analysis requirements and techniques updated. Common scheme for consequence severity classification used in EN 16602-30 and EN

40、16602-40 (based on ECSS-Q-ST-30C and ECSS-Q-ST-40C). Identification and control of safety-critical functions updated. Established link to EN 1602-10-04 “Critical-item control” (based on ECSS-Q-ST-10-04). Informative annex on European legislation and CE marking added (Annex F). DRDs revisited and upd

41、ated. Document reworked to be in compliance with ECSS standards drafting rules. BS EN 16602-40:2018EN 16602-40:2018 (E) 8 This document has been prepared under a standardization request given to CEN by the European Commission and the European Free Trade Association. This document has been developed

42、to cover specifically space systems and has therefore precedence over any EN covering the same scope but with a wider domain of applicability (e.g. : aerospace). According to the CEN-CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement

43、this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Serb

BS EN 16602-40:2018EN 16602-40:2018 (E) 9 1 Scope This Standard defines the safety programme and the safety technical requirements aiming to protect flight and ground personnel, the launch vehicle, associated payloads

45、, ground support equipment, the general public, public and private property, the space system and associated segments and the environment from hazards associated with European space systems. This Standard is applicable to all European space projects. This standard may be tailored for the specific ch

46、aracteristic and constraints of a space project in conformance with ECSS-S-ST-00.
