EN 16729-4:2018 (E) 3 European foreword This document (EN 16729-4:2018) has been prepared by Technical Committee CEN/TC 256 “Railway application”, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by June 2019, and conflicting national standards shall be withdrawn at the latest by June 2019. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN shall not be held responsible for identifying any or all such patent rights. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document. This series of European Standards EN 16729 “Railway applications – Infrastructure – Non-destructive testing on rails in track” consists of: — Part 1: Requirements for ultrasonic inspection and evaluation principles; — Part 2: Eddy current testing of rails in track; — Part 3: Requirements for identifying internal and surface rail defects; — Part 4: Qualification of personnel for non-destructive testing on rails. According to the CEN-CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. SIST EN 16729-4:2019



EN 16729-4:2018 (E) 4 Introduction Since the effectiveness of any application of non-destructive testing (NDT) depends upon the capabilities of the persons who perform or are responsible for the test, a procedure has been developed to provide a means of evaluating and documenting the competence of personnel whose duties require the appropriate theoretical and practical knowledge of the non-destructive tests they perform, specify, supervise, monitor or evaluate. An added incentive stems from the European comparability of a wide range of industrial applications requiring common non-destructive testing approaches. The regulatory aspects in this document follow EN ISO 9712. SIST EN 16729-4:2019



EN 16729-4:2018 (E) 5 1 Scope This document defines the requirements for qualification of the personnel who plan, carry out and supervise non-destructive testing in industrial sector – Railway maintenance infrastructure, on rails in switches, crossings and plain track. Safety of staff working on or near the railway track is part of the infrastructure manager safety management system and is not part of this standard. This document applies only to rail profiles meeting the requirements of EN 13674-1 and EN 13674-2. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN ISO 9712, Non-destructive testing — Qualification and certification of NDT personnel (ISO 9712) 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. ISO and IEC maintain terminological databases for use in standardization at the following addresses:

Understanding of the infrastructure shall be gained from work experience or dedicated training courses. 7 Examination 7.1 General Qualification shall cover a non-destructive testing technique as applied in the industrial sector railway maintenance infrastructure. For the examination, EN ISO 9712 applies. 7.2 Content and duration of the examination Examinations shall comprise of a general part, a sector specific part and a practical part. The sector specific part and the practical part shall be related to industrial sector railway maintenance infrastructure. For the content and duration of the examination, EN ISO 9712 applies. 7.3 Assessment of the examination For the assessment of the examination, EN ISO 9712 applies. 7.4 Requalification Within 5 years of qualification a practical examination is required in order to demonstrate competence in the industrial sector railway maintenance infrastructure. The examinations shall be carried out in accordance with EN ISO 9712. NOTE This does not apply for VT unless the inspector holds a dedicated VT competence record in accordance with EN ISO 9712. Then EN ISO 9712 applies. SIST EN 16729-4:2019
