Check samples and test panels are used to quality assessment and comparing sensitivity of sets of penetrant material. Authors made research in field of manufacturing non-metal test-objects with specified parameters, such as length a width. The paper considers a technique to determine the depth of blind closed cracks in check samples and non-metal test panels for penetrant inspection with a special tool to measure the depth of the undercut depth or a gauge indicator on the outboard support.
