| Abstract: | In order to promote the application of EPMA in examining and testing physical evidence of electrical fire, the functions and characteristics of EPMA were introduced in this paper. Two fire cases were exemplified by observing the microstructure of electrical wire melting and analyzing the composition on the micro - porous surface via EP- MA technology. Through the EPMA method, the cause behind the melted marks is able to be known, which can technically support the fire investigation. |
