DIN EN 16729-1:2016-11

This document (EN 16729-1:2016) has been prepared by Technical Committee CEN/TC 256 "Railway applications", the secretariat of which is held by DIN. This European Standard series EN 16729 "Railway applications - Infrastructure - Non-destructive testing on rails in track" consists of the following parts: Part 1: Requirements for ultrasonic testing and evaluation principles; Part 2: Eddy current testing of rails in track (planned); Part 3: Requirements for identifying internal and surface rail defects (planned). This standard represents the actual state of the art of automated ultrasonic testing of rails in track applied by European railway companies. This European Standard applies to testing of rails installed in track for detecting internal discontinuities. This part of this European Standard applies to testing equipment fitted to dedicated test vehicles or manually-propelled devices. This standard does not define the requirements for vehicle acceptance. This part of the standard does not cover the production testing of rails in a in a production plant. The European Standard specifies the requirements for testing principles and systems in order to produce comparable results with regard to location, type and size of discontinuities in rails. This European Standard is not aiming to give any guidelines for managing the result of ultrasonic rail testing. This European Standard applies only to rail profiles meeting the requirements of EN 13674-1. The responsible German committee is Subcommittee NA 087-00-01-12 AA "Inspizieren und Behandeln von Schienen" ("Monitoring and treatment of rails") at DIN Standards Committee Railway (FSF).
