Gives the procedure for determining the curing-characteristic and glass transition temperature of non-metallic materials (e.g. preimpregnated and neat resin systems, adhesives) for aerospace use by Differential Scanning Calorimetry (DSC). The results that are obtained by this method may be useful for: - assessment of the ageing behavior of the resin; - assessment of the condition of the resin; - derivation of the optimum cure (only together with other test methods e.g. T[g] determination).
