DIN 27201-7
State of railway vehicles - Basic principles and production technology - Part 7: Non-destructive testing
Zustand der Eisenbahnfahrzeuge - Grundlagen und Fertigungstechnologien - Teil 7: Zerstörungsfreie Prüfung
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") of Working Committee NA 087-00-15 AA "Zustand der Eisenbahnfahrzeuge" ("State of railway vehicles") at the DIN Standards Committee Railway (FSF) in coordination with other Working Committees of FSF and of the DKE (German Commission for Electrical, Electronic and Information Technologies). The standards of the complete works "State of railway vehicles" represent a uniform and system-compatible normative document which specifies provisions for the operation and maintenance 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: Procedures for preparation and modification of maintenance programmes - Part 2: Proof of maintenance - Part 3: Test run - Part 4: Treatment of railway vehicles following hazardous incidents - Part 5: Assessment parameters and requirements of the distribution of wheel forces and vertical wheelset forces of railway vehicles - Procedure for checking and settings (title modified) - Part 6: Welding - Part 7: Non-destructive testing - Part 8: Adhesive bonding (the draft E DIN 27201-8 shall be integrated into the project DIN 6701-4.) - 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 fibre composite components (in preparation). Wear, failures and other damage influence the operational safety of railway vehicles. Depending on the wear characteristics, application parameters and 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. The use of one or several suitable non-destructive test methods is a necessary prerequisite. The general field of application of this document is specified in DIN 27200:2011-11, Clause 1 and 3.1. This standard describes the requirements for the non-destructive tests, test personnel and workshops maintaining safety-relevant components, assemblies and components of railway vehicles. This standard does not apply to components subject to other regulations as, for example, RID or BetrSichV. For distinction between tank and railway vehicle, see Annex F. Compared with DIN 27201-7:2006-06, the following modifications have been made: a) adjustment of the foreword and the scope; b) revision of the normative references; c) 4.1 industrial sector "Railway maintenance" newly incorporated and three-level system specified; d) 4.2 "Tasks" revised; e) Annex D and Figure D.1 "Access to the industrial sector railway maintenance from other product or industrial sectors" revised; f) Annex E "Periods of training" newly incorporated; g) Annex F "Differentiation between tank and railway vehicle" newly incorporated; h) editorially revised.
