FABRICATION LABORATORY OF CALIBRATION DEFECTS FOR NON-DESTRUCTIVE TESTING EQUIPMENTS
The main non-destructive testing techniques, such as ultrasound, acoustic emission, X-ray, and eddy currents, require artificial defects for calibration purposes and often for defining reject levels. The size, shape and surface state quality of these defects must be precisely known and also guaranteed; moreover the fabrication reproducibility must be also insured. Since 1970, the Non Destructive Testing laboratories at the Joint Research Centre Ispra of the European Communities, in collaboration with ENEA (Ente Nazionale Energie Alternative), have studied and developed special fabrication techniques of artificial defects such as very precise mechanical machining, drilling, magnetoforming, punch, and spark-erosion. Replica techniques were also developed in order to guarantee the defects fabrication quality. Since 1975, the NDT laboratories at Ispra have manufactured many artificial defects (about 200 a year), especially for particular purposes. In 1983, a licensing contract was signed between CEC and ENEA and today, we present the new fabrication laboratory, installed by the ENEA. This laboratory, located at Saluggia, in Italy, was completed at the end of 1983 and is now able to produce artificial defects of high quality using all the special techniques developed at Ispra. This laboratory has the possibility to manufacture defects for public and private institutions.
