Abstract

One of the most important limitations of the penetrant testing method is its dependence on the temperature of the surfaces under examination (16°C-52°C). In order to assure the reliability of this NDT method, the Italian Institute of Welding of Genoa and the Engineering branch of ENEA are establishing an experimental program to define both standard acceptable defects (natural and artificial) and standardization of the control procedures for non-standard temperatures. This paper illustrates the first results achieved during a series of tests conducted using some penetrants for hot surfaces (50°C-140°C and 14°C-200°C); at the end of the research, all the results obtained shall be used to prepare a reference document to qualify the welding test procedures for non-standard temperatures.
