This document specifies 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.

NOTE - The specific gases permitted in cylinders constructed to this document can be limited by national or international requirements.

This document is applicable to cylinders where:

• a) the test pressure does not exceed 250 bar1) (i.e. ph <= 250 bar) for liquefied gases and 450 bar for compressed gases; or
• b) 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
• c) 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)
