This standard (EN
17、 16602-40-12:2014) originates from ECSS-Q-ST-40-12C. 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of an identical text or by endorsement, at the latest by March 2015, and conflicting national standards shall be withdrawn at the latest by March 2015.
18、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 be held responsible for identifying any or all such patent rights. This document has been prepared under a mandate given to CEN by the European Commissio
19、n and the European Free Trade Association. 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 domain of applicability (e.g. : aerospace). According to the CEN-CENELEC Internal Regulations, the nationa

22、pace projects and incorporates the IEC 61025 standard into the ECSS system. With effect from the date of approval, this Standard announces the adoption of the external document on a restricted basis for use in the European Cooperation for Space Standardization (ECSS) system. This standard may be tai
23、lored for the specific characteristic and constraints of a space project in conformance with ECSS-S-ST-00.

29、te assumptions, events and failure modes, and provides identification rules and symbols. DIN EN 16602-40-12:2014-12 EN 16602-40-12:2014 (E) 8 5 Requirements 5.1 ECSS usage restriction 5.1.1 Applicability a. The supplier shall use the FTA as defined in ECSS-Q-ST-30 and ECSS-Q-ST-40. b. The supplier s
30、hall perform a FTA for: 1. selected undesirable events which could have catastrophic, critical or major consequences; NOTE For definition for the scale of severity, refer to ECSS-Q-ST-30. 2. support of failure; 3. accident investigations. NOTE This is to limit the amount of effort in performing the
31、analysis. c. The supplier shall agree with the customer on the content of the FTA. d. The supplier shall provide the FTA for customer review. e. Where FTA is used in failure or accident investigations, the supplier shall agree with the relevant Review Board on the depth of the FTA. 5.1.2 Procedure a
32、. The supplier shall perform the FTA in conformance with the methodology and symbols described in IEC 61025. NOTE 1 IEC 61025 uses general terms to describe the FTA process, including preparations for the FTA, the procedure itself and the output report. NOTE 2 Users are encouraged to make sure that
33、they have a clear understanding and interpretation of these general terms when taken in the context of the space system under analysis. NOTE 3 The informative reference, NUREG 0492 (1991) “Fault Tree Handbook” can be used as a comprehensive reference work to complement this ECSS Standard. DIN EN 166

When using a computer program to support the FTA, the supplier shall use a computer program which fulfils the following criteria: 1. it supports the functionality which is necessary to perform the FTA; 2. it is compati
35、ble with project requirements for electronic data transfer and the interchange of data between interacting programs or tools. NOTE Although there are several proprietary software programs available for various platforms designed to assist the FT analyst, this ECSS Standard does not endorse any parti
