PROBLEM TO BE SOLVED: To provide a method and apparatus for establishing porosity standards in nondestructive inspection.SOLUTION: A plurality of samples 112 are formed using a different technique for each sample in the plurality of samples 112 such that each sample in the plurality of samples 112 has a different porosity from other samples in the plurality of samples 112. Each sample in the plurality of samples has the same set of selected properties as a selected part type 104. A porosity level is identified for each sample using volumetric data 148 extracted from a three-dimensional image 136 for each sample generated using a computed tomography system 132. A group of standards 102 is established for a group of selected porosity levels 156 from the plurality of samples 112 on the basis of the porosity level identified for each sample in the plurality of samples 112. The group of standards 102 is configured for use in performing nondestructive inspection 106 of a part 108 of the selected part type 104. |
