Forensic Testing

PGLI assisted several clients determine the cause of failure of a product via Forensic Engineering. Forensic Engineering is a scientific means of examining and analyzing structures and products relating to their failure or cause of damage.

When a product fails for no apparent reason, Scanning Electron Microscopy (SEM) and Energy–Dispersive X-Ray Spectroscopy (EDX) are performed in the microscope. These procedures can reveal the incidence of any contamination or aggressive chemical stains on the fracture or adjacent surfaces.
