Full title and description

ISO 11119-3:2020/Amd 1:2023 — Gas cylinders — Design, construction and testing of refillable composite gas cylinders and tubes — Part 3: Fully wrapped fibre reinforced composite gas cylinders and tubes up to 450 l with non-load‑sharing metallic or non‑metallic liners or without liners — Amendment 1. This amendment provides changes and clarifications to ISO 11119-3:2020 and is published as a 2‑page amendment to the 2020 edition.

Abstract

This document is Amendment 1 (2023) to ISO 11119-3:2020. It applies to the third edition of ISO 11119‑3 (2020) for fully wrapped fibre‑reinforced composite cylinders and tubes (types 4 and 5, linerless or with non‑load‑sharing liners) up to 450 litres water capacity and provides editorial and technical updates to the base text. The amendment is short (2 pages) and intended to be applied together with ISO 11119‑3:2020.

General information

Scope

ISO 11119-3:2020 (to which this amendment applies) sets minimum requirements for material, design, construction, workmanship, manufacturing processes, examination and testing at manufacture for fully wrapped fibre‑reinforced composite cylinders and tubes (type 4 with non‑load‑sharing liners, and type 5 without liners) with water capacities up to 450 l intended for storage and conveyance of compressed or liquefied gases. It covers carbon, aramid and glass fibre reinforcements in a matrix and specifies a minimum design life (see ISO 11119‑3 for full limits and exclusions).

Key topics and requirements

• Application of amendment text alongside ISO 11119‑3:2020 to clarify or correct specific clauses.
• Requirements for materials and fibre/matrix combinations used for fully wrapped cylinders (carbon, aramid, glass).
• Design and manufacturing controls for non‑load‑sharing liners and linerless constructions.
• Production examination and factory testing requirements at time of manufacture (pressure tests, visual and non‑destructive examination, marking).
• Specified limits on intended gas types and exclusions (e.g., not intended for certain toxic, oxidizing or corrosive gases as noted in the base standard).

Typical use and users

Manufacturers of composite gas cylinders and tubes, design engineers, conformity assessment bodies, testing laboratories, inspection authorities, gas suppliers and regulators use ISO 11119‑3 together with this amendment to ensure product design, manufacture and testing meet internationally accepted minimum requirements for safety and performance.

Related standards

ISO 11119 is a multipart series. Relevant related documents include ISO 11119‑1:2020 (hoop‑wrapped cylinders and tubes), ISO/AWI 11119‑2 (work item for load‑sharing metal liners / part 2), ISO 11119‑4:2016 (fully wrapped cylinders up to 150 l with load‑sharing welded metallic liners) and ISO 11623 (periodic inspection and testing of composite cylinders). These documents are commonly used together to cover different cylinder constructions, liner types and inspection regimes.

FAQ

Q: What is this standard?

A: It is Amendment 1 (2023) to ISO 11119‑3:2020 — a published 2‑page amendment that modifies/clarifies the 2020 third edition of the part of ISO 11119 dealing with fully wrapped fibre‑reinforced composite gas cylinders and tubes up to 450 l.

Q: What does it cover?

A: The base standard (ISO 11119‑3:2020) covers material, design, construction, workmanship, manufacture inspection and factory testing for fully wrapped composite cylinders and tubes (type 4 with non‑load‑sharing liners and type 5 linerless) up to 450 l for storage and conveyance of compressed or liquefied gases; the amendment provides specific corrections or clarifications to that text.

Q: Who typically uses it?

A: Cylinder manufacturers, design and materials engineers, conformity assessors, testing labs, inspection bodies, gas suppliers and regulators — any party responsible for design, manufacture, testing or approval of composite gas cylinders.

Q: Is it current or superseded?

A: The amendment was published in July 2023 and applies to the current (third) edition ISO 11119‑3:2020; users should apply the 2020 base document together with Amendment 1 (2023). Check national adoption or later revisions to confirm local status.

Q: Is it part of a series?

A: Yes — ISO 11119 is a multipart series covering composite gas cylinders (parts 1, 2, 3, 4 etc.); ISO 11119‑3 (with this amendment) addresses fully wrapped non‑load‑sharing or linerless cylinders up to 450 l, while other parts address hoop‑wrapped designs and load‑sharing liners. For inspection intervals and in‑service testing see ISO 11623.

Q: What are the key keywords?

A: Composite cylinder, fully wrapped, linerless, non‑load‑sharing liner, type 4, type 5, ISO 11119‑3, amendment, cylinder testing, design life, manufacturing requirements.
