Full title and description

ISO 10460:2018 — Gas cylinders — Welded aluminium-alloy, carbon and stainless steel gas cylinders — Periodic inspection and testing. Third edition (2018), corrected April 2019. This international standard specifies requirements, procedures and acceptance criteria for periodic inspection, testing, repair and marking of welded metal transportable gas cylinders (water capacity normally 0.5 L to 150 L, and where practical up to 450 L), excluding acetylene and some composite cylinder types.

Abstract

Specifies the requirements for the periodic inspection and testing of welded aluminium‑alloy, carbon and stainless steel gas cylinders intended for compressed and liquefied gas service to verify cylinder integrity for further service. Applies primarily to industrial gases (may also apply to LPG) and gives procedures for depressurization, external and internal visual inspection, neck and thread checks, pressure testing, repair classification, accessory inspection and marking/reporting.

Scope

Provides standardized procedures and acceptance criteria for the periodic inspection and testing of welded aluminium‑alloy, carbon and stainless steel gas cylinders of typical water capacity 0.5 L to 150 L (and, where practical, less than 0.5 L and up to 450 L). The standard excludes acetylene cylinders and fully wrapped or hoop‑wrapped composite cylinders and is intended primarily for industrial gases; it also references ISO 10464 for LPG‑specific considerations.

Key topics and requirements

• Intervals between periodic inspections and tests (guidance and informative annex with typical intervals).
• Safe depressurization and devalving procedures before inspection.
• External visual inspection: preparation, lighting, defect identification and acceptance/rejection criteria.
• Internal visual inspection: cleaning, access, lighting and acceptance/rejection criteria.
• Neck and thread inspection (cylinder‑to‑valve threads, neckrings, collars).
• Pressure test procedures, test equipment, test criteria and acceptance thresholds (including test hold times and allowable pressure limits).
• Repair classification and permitted/forbidden repairs (major vs. minor); requirements for rendering cylinders unserviceable.
• Inspection of valves and accessories, drying, cleaning, painting/coating, re‑valving and marking/reporting after inspection.
• Requirements for marking next inspection dates and recordkeeping; illustrative date‑ring system in an informative annex.

Typical use and users

Used by cylinder inspection and testing stations, gas manufacturers and fillers, cylinder repair workshops, regulatory and conformity assessment bodies, transport and safety officers, and quality/safety engineers responsible for cylinder fleet management and maintenance programs. The standard is a practical day‑to‑day reference for trained inspectors performing periodic re‑qualification of welded metal gas cylinders.

Related standards

Revises and replaces ISO 10460:2005 (previous edition). For LPG‑specific requirements see ISO 10464. Related ISO work is produced by ISO/TC 58/SC 4 (gas cylinders). National and regional adoptions (EN/ISO variants) exist and may include additional national annexes.

FAQ

Q: What is this standard?

A: ISO 10460:2018 is an international standard that specifies procedures and acceptance criteria for periodic inspection, testing and requalification of welded aluminium‑alloy, carbon and stainless steel gas cylinders.

Q: What does it cover?

A: It covers safe preparation (depressurization and devalving), external and internal visual inspections, neck and thread checks, pressure testing procedures and acceptance criteria, repair guidance, accessory inspection, marking and recordkeeping; informative annexes give typical inspection intervals and an example date‑ring system.

Q: Who typically uses it?

A: Cylinder inspectors, testing stations, gas suppliers/fillers, repair shops, safety and compliance officers, and regulatory bodies responsible for transport and storage of pressure vessels.

Q: Is it current or superseded?

A: ISO 10460:2018 is the current (3rd) edition published in September 2018 with a corrected version released in April 2019; it supersedes ISO 10460:2005. Users should check national adoption dates or later confirmations/updates as standards are reviewed periodically.

Q: Is it part of a series?

A: It is part of the ISO/TC 58 gas cylinder family of standards and is used alongside related standards (for example ISO 10464 for certain LPG considerations and various ISO/CEN adoptions). National/regional EN versions may exist.
