This document specifies minimum requirements for the material, design, construction and workmanship, manufacturing processes, examination and testing at time of manufacture for:

  • type 2 composite hoop wrapped cylinders or tubes with a load-sharing metal liner and composite reinforcement on the cylindrical portion only;

  • water capacities up to 450 l;

  • the storage and conveyance of compressed or liquefied gases;

  • cylinders and tubes with composite reinforcement of carbon fibre, aramid fibre or glass fibre (or a mixture thereof) within a matrix or steel wire to provide circumferential reinforcement;

  • a minimum design life of 15 years.

This document does not address the design, fitting, and performance of removable protective sleeves.

NOTE 1

References to cylinders in this document include composite tubes if appropriate.

NOTE 2

ISO 11439 applies to cylinders intended for use as fuel containers on natural gas vehicles and ISO 11623 covers periodic inspection and re-testing of composite cylinders.
