The not-destructive test with Penetrating Liquids is one of the most traditional analysis method, used by aeronautic industry in order to highlight superficial breaks on any not-porous material (metal, ceramic, glass, plastic and so on); this feature makes this test usable in many production phases and/or checks on aircrafts components. However, in order to have a profitable use of this analysis method, some operating conditions are necessary, first of all the breaks to be highlighted (besides being superficial), must be “open on surface”.
