Frequently Asked Questions
CEN/TC 256/SC 1/WG 50 is a Subcommittee within the European Committee for Standardization (CEN). It is named "Monitoring and treatment of rails" and is responsible for: Rail monitoring, rail defect management and treatment of railway rails in switches, crossings and plain track This committee has published 10 standards.
CEN/TC 256/SC 1/WG 50 develops CEN standards in the area of Information technology. The scope of work includes: Rail monitoring, rail defect management and treatment of railway rails in switches, crossings and plain track Currently, there are 10 published standards from this subcommittee.
The European Committee for Standardization (CEN) is a public standards organization that brings together the national standardization bodies of 34 European countries. CEN provides a platform for developing European Standards (ENs) and other technical documents in relation to various products, materials, services, and processes, supporting the European Single Market.
A Subcommittee (SC) in CEN operates under a Technical Committee and focuses on a specific subset of the TC's scope. Subcommittees develop standards and technical specifications in their specialized area, reporting to their parent Technical Committee. They may also have working groups for detailed technical work.
This document specifies the procedures of visual testing and ultrasonic testing of rail welds in track for rail profiles meeting the requirements of EN 13674-1.
This document specifies the principles for testing procedures for manufactured welds. This document defines the procedure for repair welds and joint welds. This document does not define the number of welds to be tested.
This document is not concerned with the approval of the welding procedure.

This European Standard lays down the technical requirements and the measurements to be made for the acceptance of work for reprofiling longitudinally and/or transversely the heads of railway rails in switches, crossings and expansion devices.
For acceptance purposes two classes of longitudinal profile and three classes of transverse profile tolerance are defined.
It applies to reprofiled vignole railway rails and associated switch rails 46 kg/m and above.

This European Standard specifies the technical requirements and the measurements to be made for the acceptance of work to reprofile longitudinally and/or transversely the heads of railway rails. For acceptance purposes, two classes of longitudinal profile and three classes of transverse profile tolerance are defined.
Annexes describe procedures to verify reference instruments to be used for these measurements as well as methods to approve non-reference instruments to be used for measurements.
This European Standard applies to reprofiled vignole railway rails 46 kg/m and above.
It does not apply for acoustic rail reprofiling.
A form of acceptance documentation that may be used is given in Annex E.
