Railway infrastructure - Non-destructive testing on rails in track - Part 1 : requirements for ultrasonic inspection and evaluation principles

This document specifies the requirements for testing principles and systems to produce comparable results with regard to location, type and size of discontinuities in rails. This document does not aim to give any guidelines for managing the result of ultrasonic rail testing. This document only applies to flat bottom (Vignole) railway rail profile 43 kg/m and above.This document only applies to continuous testing of rails installed in track for detecting internal discontinuities.This document only applies to testing equipment fitted to dedicated test vehicles or manually propelled devices. This document treats welded joints as plain rail.This document does not define the requirements for vehicle acceptance. This document does not apply to ultrasonic testing of rails in a production plant.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
