BS EN 16729-3 discusses requirements for identifying internal and surface rail defects. BS EN 16729-3 specifies the NDT methods used to detect internal and surface rail defects and the suitability of each method for the detection and evaluation of typical rail defects of rails installed in the track.
Note1: BS EN 16729-3 does not specify the assessment criteria of rail defects and the derived actions.
Note2: BS EN 16729-3 applies only to rail profiles meeting the requirements of EN 13674‑1.
BS EN 16729-3 on requirements for identifying internal and surface rail defects is useful for:
A critical defect is a rail defect that affects the safety of train operations. All rail defects may be detected and assessed by a suitable NDT method. The NDT method used is selected depending on the type, size, and location of the defect to be detected. BS EN 16729-3 provides various methods for identifying internal and surface rail defects. This will ensure the safety of the train and the users.
