Overview
CEN ISO/TS 25107:2019 - Non-destructive testing (NDT) training syllabuses provides requirements and recommendations to harmonize and maintain the general standard of training for NDT personnel. The Technical Specification defines minimum structured training content to ensure candidates are eligible for qualification examinations that lead to third‑party NDT certification. It covers both general NDT principles and method‑specific syllabuses at Levels 1, 2 and 3.
Key topics and requirements
- Scope of training: The TS specifies syllabus content for theoretical and practical learning aimed at industrial needs and third‑party certification eligibility.
- Method coverage: Includes syllabuses and recommended content for:
- Radiographic testing (RT)
- Ultrasonic testing (UT)
- Eddy current testing (ET)
- Penetrant testing (PT)
- Magnetic particle testing (MT)
- Leak testing
- Acoustic emission testing (AE)
- Visual testing (VT)
- Thermographic testing
- Strain gauge testing
- Competence levels: Guidance is provided for Levels 1, 2 and 3 training syllabuses, addressing the progression from basic operator skills to advanced interpretation and supervisory responsibilities.
- Core subjects: Standardized terminology, role and responsibilities of NDT personnel, interpretation of indications, safety (including radiation safety), environmental considerations, and ethical/legal aspects of signing test reports.
- Training structure: Emphasizes a balance of theory and hands‑on practice, and alignment with recognized certification schemes to support mutual recognition across organizations and jurisdictions.
Applications and users
This Technical Specification is designed for practical use by:
- NDT training organizations and instructors - to develop method‑specific syllabuses and course plans that meet minimum industry expectations.
- Certification bodies and examiners - to verify candidate preparedness and eligibility for third‑party certification programs.
- Employers and plant operators - to set training requirements for in‑house inspection teams in sectors such as aerospace, power generation, oil & gas, pipelines, civil engineering and manufacturing.
- NDT personnel (Levels 1–3) - as a reference for expected knowledge areas, safety obligations and the scope of practical skills needed for certification.
Related standards
- ISO/TS 25108 (requirements for NDT training organizations)
- ISO 9712 and EN 473 (certification schemes and qualification requirements referenced for alignment)
- EN 1330 (NDT terminology)
CEN ISO/TS 25107:2019 is a practical guide for standardizing NDT training content, improving workforce competence, and supporting consistent, auditable pathways to recognized NDT certification.
