Overview

EN ISO 9712:2022 - Non-destructive testing (NDT) - Qualification and certification of NDT personnel (ISO 9712:2021) is a CEN-adopted international standard that defines requirements for certifying personnel who perform industrial NDT. The standard covers a broad set of NDT methods and specifies the competency framework, examination and certification system, responsibilities of certification bodies, and administrative requirements. It is intended for industrial applications (medical applications are excluded) and supports third‑party conformity assessment schemes.

Key topics and requirements

• Covered NDT methods: acoustic emission, eddy current, leak testing (excluding hydraulic pressure tests), magnetic testing, penetrant testing, radiographic testing, strain gauge testing, thermographic testing, ultrasonic testing, and visual testing (direct unaided visual tests and visual tests performed while applying another NDT method are excluded).
• Certification levels: the standard establishes multiple competence levels (commonly Level 1, Level 2 and Level 3) with distinct roles and responsibilities for test performance, interpretation and procedure development.
• Eligibility and competence: requirements for training, documented industrial NDT experience, vision standards (near vision and colour vision), and prerequisites for progression between levels.
• Examinations and grading: structured examination elements (general, specific, practical, and for Level 3, managerial/technical elements), rules for examination conduct, re‑examination and supplementary exams.
• Roles and responsibilities: expectations for certification bodies, authorized qualification bodies, examination centres, examiners, referees, employers, candidates and certificate holders.
• Certification administration: certificate issuance, validity, conditions of certification, and requirements for maintaining competence.
• Applicability to other methods: can be applied to other NDT techniques provided a comprehensive certification scheme exists and the method is supported by standards or validated by the certification body.
• Regulatory link: includes informative Annex ZA relating to EU Directive 2014/68/EU (pressure equipment), providing presumption of conformity where applicable.

Practical applications

• Ensures consistent competency of NDT personnel across industry sectors (manufacturing, oil & gas, power generation, transportation, pressure equipment).
• Supports quality assurance, safety and regulatory compliance by specifying how personnel are trained, examined and certified.
• Facilitates third‑party certification useful for contract compliance, procurement and inspection regimes.
• Helps employers implement reliable NDT programs and choose qualified inspectors for welds, components and in-service inspections.

Who should use this standard

• Certification bodies and accreditation organizations
• NDT training providers and examination centres
• Employers, inspectors and NDT technicians/engineers
• Asset owners, quality managers and regulators involved in inspection and conformity assessment
