Overview
ISO 11484:2019 defines an employer’s qualification system for non‑destructive testing (NDT) personnel working on steel products. It applies to Level 1 and Level 2 NDT personnel who test specific steel product types (tubes/pipes, flat products, long products, rails, bars, sections, rods and wires). The standard is focused on employer‑issued qualifications for a specific steel product and a specific NDT method, and is primarily intended for predominantly automated or semi‑automated NDT in the steel industry.
Key topics and requirements
- Scope and applicability: Qualification is product‑ and method‑specific for steel products (seamless/welded tubes, plates, rails, bars, wires, etc.).
- NDT methods covered: Eddy current (ET), Leak testing (LT), Liquid penetrant (PT), Magnetic testing (MT, including magnetic particle and magnetic flux‑leakage), Radiographic (RT), Ultrasonic (UT), Visual testing (VT).
- Qualification levels: Requirements for Level 1 and Level 2 personnel, with roles and capabilities defined.
- Employer responsibilities: Establish an employer’s qualifying body, manage training, examinations, records and re‑qualification under the employer’s responsibility.
- Training & experience: Training syllabuses, job‑specific training and industrial NDT experience under qualified supervision are required prior to qualification.
- Examination structure: General, specific and practical examinations (conduct, content and grading) are specified to assess competence.
- Vision and fitness: Vision acuity requirements for all levels (reference to ISO 18490).
- Records & validity: Qualification records, including provisions for digital qualification records, validity periods, re‑validation and renewal, plus file retention and transition rules for examiners.
- Alignment: Takes into account or aligns with ISO 9712 where applicable, while allowing employer‑based, job‑specific qualification for steel product testing.
Applications and who uses it
- Steel mills and tube/pipe manufacturers implementing NDT for production quality control.
- NDT managers, QA/QC teams and human resources responsible for workforce qualification and competence.
- Employers who operate automated NDT lines and need to issue method‑ and product‑specific qualifications.
- Level 3 personnel and internal examiners who design and grade employer examinations and supervise training.
Using ISO 11484:2019 helps organizations demonstrate consistent competence of NDT personnel and supports product integrity and compliance in steel manufacturing.
