Abstract

The invention relates to the use of a cylindrical test body with one or more spherical cavities for testing the function and defect recognition quality of systems for the automatic recognition of defects in castings and method for the manufacture thereof. All the prior art testing possibilities are not in accordance with practice and suffer from different advantages. The invention surprisingly obviates this problem by the use of a cylindrical test body with one or more spherical cavities for testing the function and defect recognition quality of systems for the automatic recognition of defects in castings and which is fixed on or in the casting to be tested. Thus, the invention has created test bodies or objects, which better approximate the shape of natural defects and which are simple and inexpensive to manufacture in reproducible manner. These test bodies contain one or more spherical cavities optionally having different sizes and positions.
