ActiveTechnical determination methods for electrical fire evidence—Part 8: Method of thermal analysis
电气火灾痕迹物证技术鉴定方法 第8部分: 热分析法
Application Summary AI generated
This standard specifies the use of thermal analysis techniques, such as differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA), to identify electrical fire evidence by analyzing the thermal decomposition characteristics of materials. It is applied in forensic fire investigation and electrical accident analysis to determine whether copper or aluminum conductors have been heated by electrical faults versus external fires. The method is used by fire investigation agencies, testing laboratories, and safety authorities in China for technical identification of fire origins and causes.
