Overview
EN ISO 18119:2018/A2:2024 (ISO 18119:2018/Amd 2:2024) is Amendment 2 to the international standard covering periodic inspection and testing of seamless steel and seamless aluminium‑alloy gas cylinders and tubes. Approved by CEN in June 2024, this amendment updates normative references and specific requirements for non‑destructive testing (NDT) personnel and ultrasonic testing (UT) operations. The amendment is intended for adoption as a national standard across CEN member countries.
Key topics and technical requirements
- Scope update: Applies to periodic inspection and testing procedures for seamless steel and aluminium‑alloy gas cylinders and transportable tubes (as per ISO 18119).
- Normative references: Title of ISO 10286 is updated to “ISO 10286 - Gas cylinders - Vocabulary”; ASNT SNT‑TC‑1A is added as an acceptable reference for personnel qualification and certification in NDT.
- UT personnel qualifications (clause 14.4.2.5):
- UT (ultrasonic testing) equipment operation and supervision must be carried out by personnel who meet ISO 9712 or ASNT SNT‑TC‑1A, or another national standard accepted by the competent authority.
- The UT operator shall meet Level I requirements and must be supervised by a Level II person.
- The testing organization must retain a Level III operator (internal employee or third party) to oversee the entire UT programme.
- Implementation and compliance: CEN members are required to publish or endorse this amendment as a national standard and withdraw conflicting standards by December 2024.
Practical applications and who uses it
This amendment is essential for organizations and professionals involved in the lifecycle and safety of gas cylinders:
- Cylinder manufacturers and repair workshops conducting periodic inspections and recertification.
- Accredited testing laboratories and NDT service providers performing ultrasonic testing and other inspection methods.
- Gas suppliers, cylinder fleet managers, and maintenance teams ensuring regulatory compliance and safe operation.
- Certification bodies, safety officers and transport compliance personnel responsible for conformity and verification.
The update clarifies personnel qualification expectations for UT, helping organizations align training, supervision and quality assurance of NDT programmes.
