Scope

This document specifies the method for accelerated moisture absorption and supersaturated
conditioning by moisture of fiber-reinforced composites using sealed pressure vessels at a
heating temperature above 100 C and saturated water vapor pressure conditions.
The purpose of this moisture absorption method is to screen materials by mechanical or thermal
properties.
This document is applicable to fiber-reinforced composites with a glass transition temperature
(Tg) greater than 150 C, including carbon fiber-reinforced thermoset composites (CFRP),
carbon fiber-reinforced thermoplastic composites (CFRTP) and glass fiber-reinforced
composites, etc.
