Abstract: In this paper, combined with the contents of the eddy current part of the NB/T 47013-2015 Nondestructive Testing of Pressure Equipments, the test items and requirements for the eddy current testing system are introduced and analyzed. And the countermeasures of nondestructive testing instrument data trace were put forward. This paper is conductive to unify eddy current testing methods in the application of NB/T 47013-2015 and is helpful to ensure the reliability of product inspection.
