Manufacturing Technology and an Investigation of Samples for Testing Instruments for the Capillary Nondestructive Testing of Nonmetals

Ways of manufacturing nonmetallic control samples for capillary flaw detection are described. Several cracks, corresponding to different classes of sensitivity, are produced in one sample. A positive effect is achieved by creating a base of a nonmetal material – epoxy adhesive, in which the defects...

Beschreibung
Zusammenfassung:	Ways of manufacturing nonmetallic control samples for capillary flaw detection are described. Several cracks, corresponding to different classes of sensitivity, are produced in one sample. A positive effect is achieved by creating a base of a nonmetal material – epoxy adhesive, in which the defects are obtained by etching foil of the required size. The results of tests of such control samples on a multiplicity of use and temperature effects are presented.
