ISO 11114-5:2022 PDF

Scope: This document specifies some gas compatibility test methods to evaluate plastic materials suitable for use in the manufacture of composite gas cylinder liners. It is also applicable to the evaluation of the suitability of plastic matrix materials used for Type 5 cylinders. Some fluids like water, used for cylinders testing, can react positively or negatively when in contact with plastic liners. This compatibility issue is not covered by this document.
