Gas cylinders – Non-refillable metallic gas cylinders – Specification and test methods

Standard objective is to specify requirements for the material, design, inspections, construction and workmanship, manufacturing processes, and tests at manufacture of non-refillable metallic gas cylinders of welded, brazed, or seamless construction. This document also specifies the requirements for the non-refillable sealing devices and their methods of testing. It is applicable to non-refillable metallic gas cylinders for compressed and liquefied gases.

This document is applicable to cylinders where:

  1. the test pressure does not exceed 250 bar (i.e. ph ≤ 250 bar) for liquefied gases and 450 bar for compressed gases;
  2. the product of the test pressure and the water capacity does not exceed 1 000 bar·litres (i.e. ph V ≤ 1 000 bar l); or
  3. the test pressure exceeds 45 bar and the water capacity does not exceed 5 l (i.e. for ph > 45 bar, then V ≤ 5 l).

This document is identical to, and has been reproduced from, ISO 11118:2025, Gas cylinders – Non-refillable metallic gas cylinders – Specification and test methods.
