Investigation: the investigation was performed using a keyence vhx-5000 digital microscope.The analysis of the fracture pattern illustrated a forced fracture due to overload.No pores, inclusions or foreign bodies could be found on the point of rupture.The uneven pin is an indicator of an overload force, most likely a leverage effect.Conclusion and root cause: based on the information available as well as a result of our investigation the root cause of the failure is most probably related to an insufficient usage.Rational: this kind of instrument is designed for delicate use only.It is almost certain that a mechanical overload situation led to the breakage.Visual investigation indicated tat the quality requirements are within the specified tolerance range.No capa is necessary.
