ISO 11357 specifies several differential scanning calorimetry (DSC) methods for the thermal analysis of polymers and polymer blends, such as. thermoplastics (polymers, moulding compounds and other moulding materials, with or without fillers,fibres or reinforcements);. thermosets (uncured or cured materials, with or without fillers, fibres or reinforcements);. elastomers (with or without fillers, fibres or reinforcements).ISO 11357 is intended for the observation and measurement of various properties of, and phenomenaassociated with, the above-mentioned materials, such as. physical transitions (glass transition, phase transitions such as melting and crystall
