Overview

EN ISO 11118:2015/prA1 (ISO 11118:2015/DAM 1:2017) is an amendment to the international standard for non-refillable metallic gas cylinders. It updates the specification and test methods for single-use metallic gas cylinders, clarifying prototype test requirements and the defined procedure for testing non-refillability (leakage via the valve). The document is produced under ISO/TC 58/SC 3 and adopted in the CEN parallel process.

Key Topics and Requirements

• Scope: Applies to metallic, non-refillable (one-way) gas cylinders and the tests necessary to demonstrate safe, single-use performance.
• Testing for non-refillability (valve leak test):
  • The amendment replaces the valve-test procedure in sub‑clause A.3.2.4. Key steps include:
    • Attach the valve stem to an empty container of the same water capacity as the cylinder intended for use.
    • Apply a continuous positive pressure of 10% of p_vt, but not less than 2 bar, at the valve outlet with the valve open.
    • After 1 hour, the pressure in the connected container shall not exceed 5% of the applied pressure.
• Prototype testing schedule:
  • Sub‑clause A.4.2 now requires a minimum of 50 non‑refillable cylinders, guaranteed by the manufacturer to represent the new design, to be made available for prototype testing.
• Standards governance: The amendment was circulated as a draft for comment and includes typical ISO foreword and patent-declaration notices; final users should confirm publication status and national adoption.

Applications and Who Uses It

• Manufacturers of non‑refillable metallic gas cylinders use this standard to design, validate and document compliant one‑way cylinder designs.
• Testing laboratories and inspection bodies apply the specified test methods (valve leak tests, prototype test programs) to assess conformity.
• Regulatory authorities and purchasers refer to the standard to ensure safety, performance and legal compliance for single‑use cylinder products.
• Design and safety engineers use the requirements to inform material selection, valve integration and batch testing strategies.

Related Standards

• Produced by ISO/TC 58/SC 3 (cylinder design); users should also consult other ISO/CEN standards covering refillable cylinders, valve components and transport of compressed gases for complementary requirements and regulatory alignment.
