Overview
This International Standard specifies the consolidated basic principles of Event Tree Analysis. It provides guidance on modelling the consequences of an initiating event as well as analysing these consequences qualitatively and quantitatively in the content of dependability and risk-related measures. Specifically, this International Standard deals with the following topics regarding event trees: a) definition of the essential terms as well as description of the use of the symbols and types of graphic representations; b) specification of the procedural steps for establishment of an event tree; c) drawing up assumptions, limitations and advantages when the analysis is carried out; d) determination of the relationships to other reliability and risk related methods and explanation of suitable fields of application; e) provision of guidelines for the qualitative and quantitative aspects of analysis; f) list of practical examples. This International Standard can be applied in any branch of industry, in which reliability and risk related measures for the consequences of a starting event have to be assessed. The responsible Committee is K 132 "Zuverlässigkeit" ("Dependability") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
