摘要
A method and arrangement for testing the serviceability and for setting and calibrating a test apparatus for the non-destructive electrical and/or magnetic testing of metallic blanks, particularly steel slabs, for defects, such as surface or below-surface cracks, laps, shrinkholes, blowholes or the like, comprising inspecting means capable of detecting defects such as these and mounted for displacement relative to the surface of the blank to be tested, test plate simulating a defective metallic blank being brought up to the test apparatus in a position in which they are in substantial alignment with the surface of the blank to be tested, the inspecting means of the test apparatus being tested by the test plates for working order and calibrated.
