La présente partie de cette Norme européenne spécifie les méthodes d'essais non destructifs utilisées pour détecter les défauts internes et de surface des rails, ainsi que la pertinence de chaque méthode pour la détection et l'évaluation des défauts affectant couramment les rails en voie.
La présente partie de cette Norme européenne ne spécifie pas les critères d'évaluation des défauts de rails ni les actions effectuées en conséquence.
La présente partie de cette Norme européenne s'applique uniquement aux rails dont les profils répondent aux exigences de l'EN 13674 1.
Železniške naprave - Infrastruktura - Neporušitveno preskušanje na progi - 3. del: Zahteve za ugotavljanje notranjih in površinskih napak na progi
Ta del tega evropskega standarda določa metode neporušitvenega preskušanja (NDT), ki se uporabljajo za zaznavanje notranjih in površinskih napak na progi ter primernost vsake metode za zaznavanje in ocenjevanje običajnih napak na tirih, nameščenih na progi.
Ta del tega evropskega standarda ne določa kriterijev ocenjevanja napak na progi in izpeljanih dejanj.
Ta del tega evropskega standarda se uporablja le za profile tirnic, ki ustrezajo zahtevam standarda EN 13674-1.

Figure 5 — Principle of automatic visual inspection 5.4.2 Test area Machine Vision Systems for rail inspection and automatic identification are capable of inspecting the head, web and the upper surface of the rail foot for surface-breaking defects and damage. It is possible that the under head/web area is not examined due to line of sight depending upon the system used. 5.4.3 Example applications Examples of fault conditions identified by automatic visual inspection systems are: — horizontal/vertical cracking; — corrosion; — squats; — wheel burns; — head checks; — shelling; — corrugation; — missing or damaged components associated with the rail (for example fish plates, insulated joints, chairs, clips).

Inspections can be carried out using: — manual systems using individual hand-held transducers; — trolleys with multiple transducers which are usually pedestrian operated; — vehicle mounted equipment with multiple transducers; to enable detection and sizing of: — RCF cracks (Head Check); — cracks at cross section changes in machined rails (only detection). 5.7 Magnetic particle testing – MT 5.7.1 Description Magnetic particle inspection is a visual inspection method in which the material subjected to an inspection is magnetised either by induced magnetic field or electric current. Strong areas of flux leakage occur at the flaw sites. The component is covered in iron particles (commonly in the form of a magnetic ink). The iron particles will concentrate at the site of the flux leakage (flaw) providing a visible in
