Full title and description

STB DIN EN ISO 11114-2:2022-02 — Gas cylinders — Compatibility of cylinder and valve materials with gas contents — Part 2: Non‑metallic materials. This is the German (DIN / EN) adoption of ISO 11114-2 (third edition) providing guidance and test-related information for selecting and evaluating non‑metallic materials used in gas cylinders, valves, tubes and pressure drums (composite and laminated materials; excludes ceramics, glass and adhesives).

Abstract

This document gives guidance on the selection and evaluation of compatibility between non‑metallic materials for gas cylinders and valves and the gas contents. It considers how gas exposure can change material or mechanical properties (chemical reactions or physical state changes). The compatibility data refer primarily to single component gases but can be used for mixtures; cryogenic fluids are excluded (see ISO 21010). The standard is intended for composite and laminated materials and does not cover basic mechanical design properties or the quality of delivered gas.

Scope

Provides guidance and test‑related information to assess compatibility between non‑metallic materials in contact with stored gases in cylinders, valves, tubes and pressure drums. It applies chiefly to composite and laminated non‑metallic materials and addresses how gases can alter material properties. It is not intended for ceramics, glasses, adhesives, cryogenic fluids (covered by ISO 21010), nor for defining basic mechanical design properties — those are expected to come from material suppliers or other design standards.

Key topics and requirements

• Guidance on selection and evaluation of non‑metallic materials for gas cylinder and valve applications.
• Consideration of gas‑induced changes to material and mechanical properties (chemical reactions, physical state changes).
• Compatibility data primarily for single component gases, with notes on applicability to gas mixtures.
• Coverage of composite and laminated materials commonly used in gas cylinders; explicit exclusions for ceramics, glass and adhesives.
• Reference to related test methods and parts of the ISO 11114 series (for metallic materials, plastic liners, etc.) and cross‑references to cryogenic rules (ISO 21010).

Typical use and users

Used by cylinder manufacturers (metallic/composite), valve and liner manufacturers, materials engineers, test laboratories, conformity assessment bodies, regulatory authorities and safety engineers involved in specifying or approving pressure receptacles and associated equipment for gaseous products. It supports material selection, compatibility testing and risk assessment for gas containment applications.

FAQ

Q: What is this standard?

A: It is the DIN/EN national adoption (DIN EN ISO 11114‑2:2022‑02) of ISO 11114‑2 (third edition) titled “Gas cylinders — Compatibility of cylinder and valve materials with gas contents — Part 2: Non‑metallic materials.” It gives guidance on selecting and evaluating non‑metallic materials in contact with gases.

Q: What does it cover?

A: The standard covers guidance and test‑related information for compatibility of non‑metallic materials (including composite and laminated materials) with gas contents, addresses gas‑induced changes to materials, and provides compatibility data primarily for single gases (with applicability notes for mixtures). It excludes ceramics, glasses, adhesives and cryogenic fluids.

Q: Who typically uses it?

A: Manufacturers of gas cylinders (including composite cylinder producers), valve and liner manufacturers, materials and design engineers, testing laboratories, certification bodies and regulators who need to assess material suitability and safety for gas containment.

Q: Is it current or superseded?

A: The text is a current published adoption (DIN EN ISO 11114‑2:2022‑02) of ISO 11114‑2:2021 (third edition). It replaced earlier national/adopted versions (for example the 2013 edition at the DIN level). Users should verify national catalogues for the latest amendments or revisions.

Q: Is it part of a series?

A: Yes — ISO 11114 is a multipart series addressing material compatibility of cylinder and valve materials with gas contents. Relevant parts include Part 1 (metallic materials), Part 2 (non‑metallic materials), Part 5 (plastic liners test methods) and other related parts; consult the ISO catalogue for the full list.

Q: What are the key keywords?

A: gas cylinders; material compatibility; non‑metallic; composite; valve materials; liners; ISO 11114; safety; testing.
