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
