Scope

This document describes several methods for thermal analysis of polymers and polymer blends using differential scanning calorimetry (DSC), such as:
—— Thermoplastic plastics (polymers containing or not containing fillers, fibers, or other reinforcing materials; molding compounds and other molding materials);
—— Thermoset plastics (uncured or cured materials containing or not containing fillers, fibers, or other reinforcing materials);
—— Elastomeric plastics (containing or not containing fillers, fibers, or other reinforcing materials).
This document is applicable to researching and determining the relevant properties of the above-mentioned materials, such as:
—— Physical transitions (glass transition, phase transitions such as melting, crystallization, polymorphic transitions, etc.);
—— Chemical reactions (polymerization, cross-linking and curing of elastomeric and thermoset materials, etc.);
—— Oxidation stability;
—— Specific heat capacity.
This document specifies the general requirements for differential scanning calorimetry, such as principles and instruments, sampling, calibration, and other common experimental steps and test reports.
Note: For specific methods, please refer to the relevant sections of GB/T 19466.
