Discontinuity Test Block
Aluminium test block with different reflector types for locating of discontinuities using techniques such as the echo, delta, tandem, transfer and angle techniques
The aluminium test block contains different reflector types that can be used for producing echoes. Five mirror-type reflectors and one crack-type reflector are differentiated. The mirror-type reflectors include three cylinders, a disk, a vertical crack and a oblique crack each with different orientations to the surface. Diffraction effects can be investigated at the crack. Different locating techniques such as the echo, delta, tandem, transfer and angle techniques are applied for the locating of discontinuities (defect search)
