Full title and description

BS EN ISO 10460:2018 — Gas cylinders. Welded aluminium‑alloy, carbon and stainless steel gas cylinders — Periodic inspection and testing. This British adoption (identical to EN ISO 10460:2018 and ISO 10460:2018, corrected April 2019) specifies practical requirements and acceptance criteria for periodic inspection, testing, repair and marking of welded gas cylinders to verify their integrity for continued service.

Abstract

This standard sets out procedures for preparing cylinders for inspection (depressurization and devalving), external and internal visual inspection, neck/thread checks, pressure test requirements, inspection of valves and accessories, repair classification and requalification, marking and record keeping. It applies primarily to refillable welded aluminium‑alloy, carbon and stainless steel cylinders of nominal water capacity from 0.5 L to 150 L (and, where practical, to smaller and larger sizes up to about 450 L) and excludes acetylene and composite cylinders.

Scope

The standard specifies requirements for periodic inspection and testing of welded aluminium‑alloy, carbon and stainless steel gas cylinders intended for compressed and liquefied gas service under pressure. It covers cylinders with nominal water capacities from 0.5 L to 150 L and — as far as practical — cylinders below 0.5 L and up to about 450 L. The document does not apply to acetylene cylinders or fully wrapped/hoop‑wrapped composite cylinders; guidance for LPG and specific applications is addressed where appropriate and reference is made to related ISO guidance and UN model regulations.

Key topics and requirements

• Intervals between periodic inspections and tests (guidance and examples; Annexes include typical intervals and date‑ring examples).
• Safe preparation procedures for inspection: depressurization, devalving and gas‑safety precautions (including handling of toxic/flammable residues).
• External visual inspection: cleaning, surface preparation, criteria for dents, corrosion, burns, weld condition and permanent attachments.
• Internal visual inspection: access, cleaning, lighting, and acceptance/rejection criteria for internal corrosion or defects.
• Neck and thread checks: cylinder‑to‑valve thread engagement, neckring/collar inspection and torque/testing guidance.
• Pressure test requirements: test equipment, test methods, acceptance/rejection criteria and special temperature/heat limits for aluminium alloys.
• Repairs and requalification: definition of major vs. minor repairs, permitted repair actions, and conditions for return to service or permanent removal.
• Inspection of valves and accessories; final operations (drying, cleaning, painting/coating, revalving, marking and stamping) and record keeping.

Typical use and users

Primary users are inspection and testing facilities, cylinder manufacturers, gas suppliers, transport and logistics companies handling refillable gas cylinders, regulatory/competent authorities and maintenance technicians. The standard is used to establish safe, compliant periodic inspection programmes, to decide acceptance/rejection of cylinders and to document requalification and stamping for further service.

Related standards

Commonly referenced standards and normative documents include ISO 10286 (terminology for gas cylinders), ISO 11114‑1 and ISO 11114‑2 (compatibility of cylinder/valve materials), ISO 25760 (procedures for the safe removal of pressure‑retaining accessories), ISO 10464 (requirements for LPG applications) and various national/regulatory requirements and UN Model Regulations (P200).

FAQ

Q: What is this standard?

A: BS EN ISO 10460:2018 is the British adoption of ISO 10460:2018 (periodic inspection and testing procedures for welded aluminium‑alloy, carbon and stainless steel gas cylinders), published nationally in 2019 and identical in technical content to the ISO and EN texts.

Q: What does it cover?

A: It covers safe preparation for inspection (depressurization, devalving), external and internal visual inspection, neck/thread checks, pressure test procedures and acceptance criteria, repair classifications and final marking/recording for refillable welded gas cylinders (typically 0.5–150 L nominal water capacity; guidance for other sizes is included where practical).

Q: Who typically uses it?

A: Inspection/testing stations, cylinder manufacturers and maintenance organizations, gas suppliers, transport operators, and competent authorities responsible for cylinder fitness and safety use this standard to define inspection programmes and acceptance criteria.

Q: Is it current or superseded?

A: ISO 10460 was published in 2018 (third edition) with a corrected version issued in April 2019; the British adoption (BS EN ISO 10460:2018) was published in August 2019 and is the current national adoption that is identical to the EN/ISO text. Users should always confirm national implementation dates and any subsequent amendments or withdrawal notices with the national standards body.

Q: Is it part of a series?

A: It is part of the family of standards addressing gas cylinders and their safe use, inspection and testing (e.g., ISO 10464 for LPG, ISO 20475 for cylinder bundles and related ISO documents on cylinder material compatibility and valve/cylinder fittings).

Q: What are the key keywords?

A: gas cylinders, periodic inspection, pressure testing, visual inspection, requalification, welded aluminium, welded steel, valve inspection, cylinder marking.
