This document specifies accelerated moisture absorption properties and supersaturated conditioning by moisture for fibre-reinforced plastics) using sealed pressure vessel at higher temperature than 100 °C with saturated water vapour at used heating temperature.
The purpose of this moisture absorbing procedure is to screen test specimens with moisture by mechanical or thermal properties.
This document applies to carbon-fibre materials and their products with either thermoset or thermoplastic matrices, with a Tg greater than 150 °C. This document can also apply to materials reinforced with other fibres (e.g. glass-fibres) with a Tg greater than 150 °C.
