This standard specifies a method for determining the value of the glass transition temperature (Tg) from dynamic mechanical properties measured during a linear temperature scan under heating conditions. Glass transition temperature refers to the transition from the glassy state to the rubbery state. The method and related procedures, commonly referred to as dynamic mechanical analysis (DMA), are applied to unreinforced and filled polymers, foams, rubbers, adhesives and fiber-reinforced plastics/composites. can do. Different modes of dynamic mechanical analysis (e.g. bending, compression, tension) can be applied as appropriate to the morphology of the source material.
