BS EN ISO 11623-2023 PDF

Full title and description

BS EN ISO 11623:2023 — Gas cylinders. Composite cylinders and tubes. Periodic inspection and testing. This British adoption of EN/ISO 11623 sets requirements for the periodic inspection and testing needed to verify the integrity of hoop‑wrapped and fully‑wrapped composite transportable gas cylinders and tubes (Types 2, 3, 4 and 5) used for compressed, liquefied or dissolved gases under pressure.

Abstract

This standard specifies requirements for periodic inspection and testing to verify fitness for continued service of composite cylinders and tubes (with aluminium‑alloy, steel or non‑metallic liners, or linerless) with water capacities from 0.5 L up to 3 000 L. It addresses visual inspection, functional checks, pressure and non‑destructive tests and gives provisions for applying the requirements to cylinders manufactured to ISO 11119 series or ISO 11515, or to comparable designs with authority approval.

• Publisher: British Standards Institution (BSI) — identical national adoption of EN ISO 11623 / ISO 11623.
• ICS / categories: 23.020.35 (Gas cylinders).
• Edition / version: 2023 edition (equivalent to ISO 11623:2023, 3rd edition).
• Number of pages: 48 pages (BSI presentation of the British/EN adoption lists 48 pages).

Scope

The standard applies to the periodic inspection and testing of hoop‑wrapped and fully‑wrapped composite transportable gas cylinders and tubes (Types 2–5), intended for compressed, liquefied or dissolved gases under pressure, with liner or linerless constructions and water capacities from 0.5 L up to 3 000 L. It is intended for cylinders manufactured to ISO 11119‑1, ‑2, ‑3, ‑4 or ISO 11515 and may be applied to other comparable designs when authorized by the competent authority or the manufacturer.

Key topics and requirements

• Periodic inspection intervals and records for composite cylinders and tubes (visual and functional checks).
• Mandatory and recommended test methods: visual inspection, hydraulic (pressure) testing where applicable, leak testing and non‑destructive testing (NDT) methods.
• Applicability to hoop‑wrapped and fully‑wrapped cylinders (Types 2, 3, 4, 5) and to a wide range of water capacities (0.5 L–3 000 L).
• Requirements for handling, marking, identification and traceability of cylinders subjected to inspection and test.
• Cross‑references and how to apply the standard alongside ISO 11119 series and ISO 11515 for design and initial type‑approval matters.

Typical use and users

Used by cylinder manufacturers, inspection and testing laboratories, gas suppliers, rental and transport companies, end‑users that operate cylinders for industrial, medical, specialty and cryogenic gases, and by regulatory/competent authorities overseeing transportable gas cylinder safety. The standard guides routine inspection programmes, test-house procedures and conformity checks.

Related standards

Key related standards include the ISO 11119 series (ISO 11119‑1, ‑2, ‑3, ‑4) and ISO 11515 (design and manufacturing of composite gas cylinders), plus national/EN adoption documents (EN ISO 11623). This 2023 edition replaces ISO/EN/BS EN ISO 11623:2015.

FAQ

Q: What is this standard?

A: BS EN ISO 11623:2023 is the British (BS) adoption of EN/ISO 11623:2023, an international standard that specifies periodic inspection and testing requirements for hoop‑wrapped and fully‑wrapped composite gas cylinders and tubes.

Q: What does it cover?

A: It covers inspection and testing procedures (visual, functional, pressure and selected NDT methods), applicability to Types 2–5 composite cylinders and tubes, and provisions for applying the requirements to cylinders made to ISO 11119 series or ISO 11515.

Q: Who typically uses it?

A: Cylinder manufacturers, inspection/test houses, gas suppliers, transport/rental companies, plant safety and maintenance teams, and competent/regulatory authorities.

Q: Is it current or superseded?

A: It is current (published 2023) and supersedes the earlier 2015 edition of ISO 11623. Organizations using the older 2015 edition should migrate to the 2023 edition for up‑to‑date inspection/testing requirements.

Q: Is it part of a series?

A: Yes — it is linked to the ISO 11119 series and ISO 11515 (standards that cover design and manufacture of composite cylinders and tubes). BS EN ISO 11623 focuses specifically on periodic inspection and testing.

Q: What are the key keywords?

A: Composite cylinders, periodic inspection, periodic testing, transportable gas cylinders, visual inspection, hydraulic test, non‑destructive testing, ISO 11119, ISO 11515.
