Full title and description

ISO 10462:2013 — Gas cylinders — Acetylene cylinders — Periodic inspection and maintenance. This International Standard specifies requirements for the periodic inspection and maintenance of acetylene cylinders (with or without solvent) used for transport and service, up to a nominal water capacity of 150 L.

Abstract

ISO 10462:2013 defines the procedures, inspection items, acceptance/rejection criteria and maintenance actions required to verify the integrity and safe continued use of acetylene (dissolved acetylene) transportable cylinders. It addresses preparation for inspection (safe depressurization), external visual inspection, examination and acceptance criteria for porous mass (monolithic and non‑monolithic), handling of valves and pressure‑relief devices, repair or replacement of porous mass, marking and record keeping. Due to the presence of porous mass, the standard does not require routine internal visual inspection of the shell or hydraulic/pneumatic pressure tests except where specifically required (e.g., after porous mass replacement).

Scope

This standard applies to seamless and welded cylinders manufactured from steel or aluminium alloys intended for the transport and service of dissolved acetylene (with or without solvent) up to a nominal water capacity of 150 L. It specifies requirements for periodic inspection intervals (as set by the UN/ADR packing instructions or national authorities), the inspection and examination of the porous mass and other cylinder components, acceptable repair actions, rejection criteria, marking and retention of inspection records.

Key topics and requirements

• Inspection scope: external visual inspection of shell, neck and fittings; examination of porous mass (monolithic and non‑monolithic); inspection of valves, pressure‑relief devices and attachments.
• Porous mass rules: detailed criteria for contamination, cracking, cavitation or compaction; use of spark‑resistant gauges and permitted repair/replacement procedures.
• Test policy: because of porous mass, routine internal visual inspection of the shell and hydraulic/pneumatic pressure tests are not required by the standard except when replacing porous mass or where otherwise indicated. Hydraulic test is required after replacement of porous mass.
• Inspection intervals: regular intervals are set by UN/ADR packing instructions or national authorities; recommended earlier first inspection for newly filled porous material (example recommendations: first periodic inspection at ~2 years for non‑monolithic and ~3 years for monolithic porous material, with regular intervals thereafter as prescribed by competent authorities).
• Repair & rejection: repair methods for non‑monolithic masses (with testing requirements), criteria for rendering cylinders unserviceable, and procedures for replacing porous mass including mandatory hydraulic test of the shell prior to re‑filling.
• Marking & records: stamping/marking rules after inspection, requirement to retain inspection records (e.g., 15 years for inspection records) and identification requirements.

Typical use and users

Primary users are cylinder inspection/test stations, cylinder manufacturers and repair facilities, gas suppliers/fillers, transport safety authorities, and organizations responsible for safe filling and re‑qualification of dissolved acetylene cylinders. The standard is used to ensure compliance with transport regulations (UN/ADR) and national inspection requirements and to provide competent persons with detailed inspection, acceptance and repair guidance.

Related standards

Typical cross‑references and normative documents used with ISO 10462 include ISO 13341 (fitting of valves to gas cylinders), ISO 22434 (inspection and maintenance of cylinder valves), ISO 13769 (requalification marking practices), and other periodic inspection/testing standards for gas cylinders (e.g., ISO 10460 / ISO 10464 family for other cylinder types). National or regional adoptions/versions may exist (e.g., EN ISO 10462).

FAQ

Q: What is this standard?

A: ISO 10462:2013 is an international standard that specifies requirements for the periodic inspection and maintenance of acetylene (dissolved acetylene) transportable cylinders up to 150 L water capacity.

Q: What does it cover?

A: It covers safe preparation for inspection (depressurization), external and porous‑mass examination, inspection criteria and limits, permitted repairs and replacements (including porous mass replacement procedures), marking, record keeping and interactions with transport/regulatory inspection intervals. It also explains when hydraulic testing is required (for example, after porous mass replacement).

Q: Who typically uses it?

A: Cylinder inspection/test stations, gas fillers and suppliers, competent technicians, cylinder manufacturers, regulatory bodies, and organizations responsible for cylinder requalification and transport safety.

Q: Is it current or superseded?

A: The 2013 edition (Edition 3) is the current ISO publication for ISO 10462 and was confirmed as current following ISO review (the edition was published in December 2013 and has an amendment published in 2019). Users should note the existence of ISO 10462:2013/Amd 1:2019 and consult the ISO catalogue or national standards body for the confirmed current status in their jurisdiction.

Q: Is it part of a series?

A: ISO 10462 is part of ISO's family of standards addressing periodic inspection and testing of transportable gas cylinders (other related ISO documents address different cylinder types and valve/marking practices). National and regional variants (e.g., EN ISO 10462) may exist.

Q: What are the key keywords?

A: acetylene, dissolved acetylene, porous mass, periodic inspection, cylinder maintenance, requalification, valve inspection, pressure‑relief device, marking, ISO 10462.
