Full title and description

STB DIN EN ISO 11114-1 2024-01 — Gas cylinders — Compatibility of cylinder and valve materials with gas contents — Part 1: Metallic materials. This German-adopted version consolidates ISO 11114-1:2020 with Amendment 1:2023 and provides requirements and compatibility information for metallic materials used in transportable gas cylinders and associated valves.

Abstract

This document specifies principles, data and selection rules for safe combinations of metallic cylinder and valve materials and the gases (single gases and gas mixtures) that contact them. It applies to seamless and welded metallic cylinders, composite cylinders and their valves used for compressed, liquefied and dissolved gases. The document does not address delivered gas product quality.

Scope

The standard provides requirements for selecting compatible combinations of metallic cylinder and valve materials and the gases with which they come into contact. Compatibility data are given for individual gases and gas mixtures, and the scope covers transportable pressure receptacles (including tubes and pressure drums) and associated valves for compressed, liquefied and dissolved gases. It excludes considerations of gas product quality.

Key topics and requirements

• Principles for assessing material-gas compatibility and safe selection of metallic materials for cylinders and valves.
• Compatibility data and classification for single gases and common gas mixtures.
• Reference lists/tables of metallic materials and their suitability with various gases (guidance for designers and manufacturers).
• Selection rules and limiting conditions (pressure, temperature, state of the gas) that affect compatibility.
• Notes on special gas effects (e.g., corrosive or embrittling environments) and cross-reference to other parts of the ISO 11114 series for detailed test methods.

Typical use and users

Manufacturers of transportable gas cylinders and valves, gas suppliers, design and safety engineers, inspection and certification bodies, and regulatory authorities use this standard to select appropriate metallic materials and to document compatibility for storage and transport of gases. It is also used by testing laboratories and procurement specialists responsible for specifying cylinder/valve material requirements.

Related standards

Part 1 is one part of the ISO 11114 series. Related items include ISO 11114-2 (non-metallic materials) and other parts that address specific test methods and hydrogen embrittlement assessment. Users should consult the other parts of the series for non-metallic materials and for detailed test procedures where indicated.

Q: What does it cover?

A: It covers principles, compatibility data and selection rules for metallic materials used in seamless, welded and composite transportable cylinders and their valves when in contact with single gases and gas mixtures. It does not address gas product quality.

Q: Who typically uses it?

A: Cylinder and valve manufacturers, gas producers and distributors, design and safety engineers, testing and certification bodies, and regulators concerned with material selection and safe gas containment.

Q: Is it current or superseded?

A: The DIN EN ISO 11114-1 consolidated edition published January 2024 is the current adopted version that incorporates the 2020 base standard and the 2023 amendment (A1). It replaces the earlier DIN/EN ISO 11114-1:2020 national publication.

Q: Is it part of a series?

A: Yes — ISO 11114 is a multi-part series dealing with compatibility of cylinder and valve materials with gas contents (Part 1: Metallic materials; Part 2: Non-metallic materials; other parts cover tests and specific issues). Consult the other parts for complementary requirements and test methods.
