ActiveTechnical determination methods for electrical fire evidence - Part 6：Micro-morphological analysis method using scanning electron microscope
电气火灾痕迹物证技术鉴定方法 第6部分：SEM微观形貌分析法
Application Summary AI generated
This standard specifies the use of scanning electron microscopy (SEM) to analyze the micro-morphology of electrical fire evidence, such as melted copper or aluminum conductors. It is applied by fire investigators and forensic laboratories in China to determine whether electrical faults or arcing caused a fire by comparing microscopic features like molten marks and dendrites. The method supports technical identification in legal and insurance contexts related to electrical fire origin and cause.
