Application Summary AI generated
This standard specifies the residual magnetic method for technically determining the cause of electrical fires. It is applied by fire investigators and forensic engineers to detect abnormal magnetic fields in ferromagnetic materials (such as steel conduits, enclosures, or structural elements) near electrical equipment after a fire, helping to identify whether a short-circuit or lightning strike was the ignition source. The method is used in fire scene investigations, particularly for analyzing electrical faults in residential, commercial, or industrial settings.
