Full title and description

St ISO 18119-2018 amd2-2024 — Gas cylinders — Seamless steel and seamless aluminium-alloy gas cylinders and tubes — Periodic inspection and testing (Amendment 2 to ISO 18119:2018). This record describes the 2024 amendment that updates or clarifies requirements for periodic inspection and testing procedures applied when cylinders and tubes are re‑introduced into service.

Abstract

This amendment (ISO 18119:2018/Amd 2:2024) applies to ISO 18119:2018 and forms part of the international framework that specifies requirements for periodic inspection and testing to verify the integrity of seamless steel and seamless aluminium‑alloy transportable gas cylinders and tubes intended for compressed and liquefied gases. The base document defines applicability by water capacity and excludes, for example, acetylene and composite cylinders where noted.

Scope

ISO 18119:2018 and its amendments specify requirements for periodic inspection and testing to verify the integrity of cylinders and tubes prior to re‑introduction into service. The standard is applicable to seamless steel and seamless aluminium‑alloy transportable gas cylinders (water capacity from 0.5 L up to 150 L) and to seamless steel and aluminium‑alloy transportable gas tubes (water capacity greater than 150 L); it also applies as far as practical to cylinders under 0.5 L. The standard excludes, where stated, the periodic inspection and maintenance of acetylene cylinders and the periodic inspection and testing of composite cylinders. Amendment 2 (2024) updates/clarifies specific requirements within that scope.

Key topics and requirements

• Periodic inspection principles for re‑qualification of seamless steel and aluminium‑alloy cylinders and tubes.
• Inspection methods and tests — visual examination, pressure/hydrostatic testing and provisions for non‑destructive examination (NDE) methods where specified or required.
• Criteria for acceptance, rejection and required remedial actions (repairs, re‑testing) before cylinders/tubes can be returned to service.
• Marking/requalification identification and record‑keeping requirements to show the type and date of the periodic requalification.
• Specific exclusions and special provisions (for example acetylene and composite cylinders are treated separately).

Typical use and users

Technical committees, inspection and test facilities, cylinder manufacturers, gas suppliers, transport and safety authorities, certified requalification stations, maintenance organizations and occupational safety professionals use this standard to establish and perform periodic inspection and requalification programs for transportable gas cylinders and tubes. It is also used by national standards bodies when adopting or aligning national rules with international practice.

Related standards

ISO 18119 interacts with other standards and documents covering gas cylinder terminology, marking, change of gas service, and specific inspection rules (for example ISO 10286, ISO 13769, ISO 11621 and related national regulations). National regulations (transport and pressure‑equipment rules) and EN/ISO adoptions may reference or incorporate ISO 18119 and its amendments.

FAQ

Q: What is this standard?

A: It is ISO 18119:2018 with Amendment 2 published in 2024 — an international standard that sets requirements for the periodic inspection and testing of seamless steel and seamless aluminium‑alloy gas cylinders and tubes.

Q: What does it cover?

A: The document covers procedures and acceptance criteria for periodic inspections and tests (visual, pressure/hydrostatic and applicable NDE methods), record‑keeping and marking for requalification of cylinders and tubes intended for compressed and liquefied gases, within specified water capacities; it excludes certain cylinder types (e.g., acetylene, composite) as noted.

Q: Who typically uses it?

A: Cylinder manufacturers, gas producers and distributors, certified test/requalification stations, inspection bodies, safety engineers and regulatory authorities use the standard to ensure safe return to service of pressured gas receptacles.

Q: Is it current or superseded?

A: The amendment ISO 18119:2018/Amd 2:2024 was published on 5 June 2024 and is a current published amendment to ISO 18119:2018. The base standard was reviewed and confirmed in 2023 and the amendment updates that base document; users should check national adoption status and any later revisions or committee drafts (ISO/CD 18119) for future replacement.

Q: Is it part of a series?

A: It belongs to the family of ISO standards and technical work of ISO/TC 58/SC 4 related to gas cylinders and their operational requirements; it is associated with other ISO documents dealing with cylinder terminology, marking and gas‑service changes.

Q: What are the key keywords?

A: Gas cylinders; periodic inspection; requalification; hydrostatic testing; non‑destructive testing; seamless steel; aluminium‑alloy; transportable tubes; ISO 18119; amendment 2024.
