WebThis test consists of breaking a 0.5 mm (alternativley 0.3mm) diameter pencil lead approximately 3 mm (+/- 0.5 mm) from its tip by pressing it against the surface of the piece. This generates an intense acoustic signal, quite similar to a natural AE source, that the sensors detect as a strong burst. The purpose of this test is twofold.
