Overview
ISO/TS 25107:2019 - "Non‑destructive testing - NDT training syllabuses" defines requirements and recommendations for NDT training syllabuses to harmonize and maintain the general standard of training of NDT personnel for industrial needs. The Technical Specification sets minimum, structured training content to ensure eligibility for qualification examinations that lead to third‑party certification (in line with ISO 9712). It covers general NDT principles, safety, and method‑specific syllabus guidance across multiple NDT techniques.
Key topics and requirements
- Three competence levels (1, 2, 3): The TS aligns with ISO 9712’s three‑level scheme and specifies the expected depth of knowledge and practical application at each level (from basic task performance to in‑depth analysis and procedure development).
- Method‑specific syllabuses: Detailed syllabus guidance is provided for major NDT methods, including:
- Radiographic testing (RT - film, digital, radioscopy)
- Ultrasonic testing (UT)
- Eddy current testing (ET)
- Magnetic particle testing (MT)
- Liquid penetrant testing (PT)
- Leak testing (LT)
- Acoustic emission testing (AT)
- Visual testing (VT)
- Thermographic testing (TT)
- Strain gauge testing (ST)
- Training structure and content allocation: The specification includes tables that recommend topic breakdowns and relative training time (e.g., general principles, equipment, testing, evaluation, quality aspects) for each method and level.
- Safety and environment: Emphasizes training in general environmental and safety considerations, including mandatory radiation safety training prior to radiographic instruction.
- Guidance for training organizations: While ISO/TS 25107 focuses on syllabuses, ISO/TS 25108 complements it by giving requirements for NDT training organizations.
- Supporting materials: Annexes provide alternative training hours for advanced techniques and bibliographic references useful for course development.
Practical applications - who uses this standard
- NDT training providers and course developers - to design course curricula that meet recognized, consistent competency expectations.
- Certification bodies and examiners - to define eligibility and ensure alignment with ISO 9712 certification pathways.
- Employers and quality managers - to specify training requirements for hiring and competency assurance in inspection programs.
- Regulators and auditors - to assess whether NDT personnel training meets industry best practice for safety and reliability.
Related standards
- ISO 9712: Qualification and certification of NDT personnel - primary certification standard referenced by ISO/TS 25107.
- ISO/TS 25108: Requirements and recommendations for NDT training organizations (complementary guidance).
ISO/TS 25107:2019 is a practical reference for establishing consistent, method‑specific NDT training syllabuses that support safe, reliable inspection and recognized third‑party certification pathways.
