GB/T 15814.3-1995

This standard specifies the use of differential thermal analysis (DTA) or differential scanning calorimetry (DSC) to test the thermal compatibility of chemical reagents used in fireworks and firecrackers. It is applied in the pyrotechnics industry to evaluate whether mixtures of oxidizers, fuels, and other additives react dangerously under heat, ensuring safe formulation and storage. The method helps manufacturers and safety regulators identify incompatible combinations that could lead to accidental ignition or explosion.
