The cylinders are constructed
- in the form of a disposable mandrel overwrapped with carbon fibre or aramid fibre or glass fibre (or a mixture thereof) in a resin matrix to provide longitudinal and circumferential reinforcement, and
- in the form of two filament wound shells joined together.
Cylinders and tubes manufactured and tested to ISO 11119-3:2013 are not intended to contain toxic, oxidizing or corrosive gases.
ISO 11119-3:2013 is limited to cylinders and tubes with composite reinforcement of carbon fibre or aramid fibre or glass fibre (or a mixture thereof) in a matrix.
Cylinders and tubes manufactured and tested to ISO 11119-3:2013 have a minimum design life of 15 years.
