State of railway vehicles - Basic principles and production technology - Part 11: Procedure for preparation of fault tolerance concept
Zustand der Eisenbahnfahrzeuge - Grundlagen und Fertigungstechnologien - Teil 11: Verfahrensweise zur Erstellung eines Fehlertoleranzkonzeptes
Overview
This standard has been prepared by Subcommittee NA 087-00-15-01 UA "Grundlagen und Fertigungstechnologien" ("Terms and definitions for the reliable state of railway vehicles") at Working Committee NA 087-00-15 AA "Zustand der Eisenbahnfahrzeuge" ("State of railway vehicles") of the Railway Standardization Committee (FSF), in coordination with other working committees of the FSF and the German Commission for Electrical, Electronic and Information Technologies (E) and contains safety specifications. The standards of the complete works "State of railway vehicles" represent a uniform and system-compatible normative document which specifies the limit state for the safe operation and processes to maintain the target state of standard gauge railway vehicles. All documents of the complete works are listed in DIN 27200, Supplement 1. DIN 27201 "State of railway vehicles - Basic principles and production technology" consists of: - Part 1: Maintenance programme - Part 2: Proof of maintenance - Part 3: Test run - Part 4: Treatment of railway vehicles following hazardous incidents - Part 5: Checking of wheel forces and vertical wheelset forces of railway vehicles - Part 6: Welding - Part 7: Non-destructive test - Part 8: Adhesive bonding - Part 9: Measuring - Part 10: Thermal spraying - Part 11: Procedure for preparation of fault tolerance concept - Part 12: Mandatory supervision equipment permanently installed in railway vehicles - Part 13: Maintenance of and with fibre composite parts of railway vehicles (in preparation). Wear, failures and other damage influence the operational safety of railway vehicles. Depending on the wear characteristics, application parameters, the current state of the railway vehicles and the cost effectiveness, a maintenance system shall be specified by which it is ensured that the necessary technical target state is maintained. In case of deviations from the technical target state, measures shall be immediately taken which serve for restoring safety of rail transport. For this case, measures and the procedure are specified in the fault tolerance concept. The general scope of this document is specified in DIN 27200:2011-11, clauses 1 and 3.1. This standard specifies the measures and the procedure for serious damage on the vehicle/entity treated affecting the intended strength and where, as a result, a concept is formed containing measures ensuring adequate safety according to paragraph 2(2) of the EBO (Railway Construction and Operations Act) of the vehicle/entity treated. The following modifications have been made with respect to DIN 27201-11:2004-08: a) a) adaptation of the foreword. b) adaptation of the scope. c) update of the standard series. d) update of the normative references. e) term "electrical utility" has been replaced by "owner/electrical utility/ECM". f) revision of the term "expert team". g) correction of non-destructive testing (NDT) according to DIN 27201-7 in 5.6. h) replacement of term "component" by "entity treated". i) Figure A.1 "Development and concept of fault tolerance concept" adopted according to amendment e) and moved to clause 4. j) general editorial revisions. The standard DIN 27201-11 is one part of the complete work "State of railway vehicles" which is notified according to the Communication from the Government of the Federal Republic of Germany to the Commission of the European Communities as national safety rules for the German railway system according to article 8, paragraph 2 of Directive 2004/49/EC of the European Parliament and of the Council of 29 April 2004 on safety on the Community's railways. The European Railway Agency (ERA) has included these standards in particular in the ERA guide for the member states about the notification of national safety rules. Communication from the Government of the Federal Republic of Germany to the Commission of the European Communities of 25 January 2008. The most current Communication is valid.
