【摘要】：电气火灾物证检测过程中判定一次短路熔痕性质鉴定意见关乎火灾调查工作进行,必须做到科学、客观。当前电气火灾原因技术鉴定方法宏观法和金相法国标只有比较笼统的定性判据,缺乏参考图谱和详细说明,而实际火灾案例中一次短路送检物证特征又鲜有总结分析。本文对民宅、仓库和车间三类场所典型一次短路火因的实际火灾案例中熔痕迹物证痕物证外观和金相特征进行分析和总结,并与国标特征描述和模拟实验样品熔痕特征进行对比分析,总结分析一次短路熔痕一般特征和发生环境的相关性,给出鉴定应用与实践中应注意的要点,为电气火灾一次短路熔痕物证判定提供参考判据。
[Abstract]:In the process of testing electrical fire evidence, judging the nature of a short-circuit melt mark is related to the work of fire investigation, and must be scientific. Objective. At present, there are only general qualitative criteria for the technical identification method of electrical fire and metallographic French standard, lacking reference map and detailed explanation. However, in the actual fire case, the characteristics of the physical evidence of a short circuit inspection are seldom summarized and analyzed. In the actual fire cases of typical primary short-circuit fire in warehouse and workshop, the appearance and metallographic features of the material evidence evidence of the fusion trace are analyzed and summarized, and compared with the national standard characteristic description and the simulation experiment sample melting mark characteristic, and then carries on the contrast analysis with the national standard characteristic description and the simulation experiment sample melting mark characteristic. This paper summarizes and analyzes the correlation between the general characteristics of a short-circuit melting mark and its occurrence environment, and points out the key points that should be paid attention to in the identification, application and practice, and provides a reference criterion for judging the physical evidence of a short-circuit melting mark in an electrical fire.
