Application Summary AI generated
This standard specifies the metallographic method for determining the cause of electrical fires by analyzing the microstructure of electrical conductors and components. It is applied by fire investigators and forensic engineers to identify whether a fire originated from electrical faults, such as short circuits or overloads, based on changes in metal grain structure. The method is used in fire scene investigations, laboratory analysis, and legal proceedings to establish the technical cause of electrical fires.
