T.O. 33B-1-12-13application procedures for fluorescent penetrant (Type I) and visible-dye penetrant (Type II) are similar, the processflow charts are applicable to both types of penetrants.2.2.8 Sensitivity.The term "sensitivity", when used in conjunction with penetrant inspection processes refers to the ability to detectflaws. Sensitivity, when used in this context, is a relative factor. More sensitive inspection processes are capable ofdetecting smaller flaws than less sensitive processes. Among the several factors that influence the sensitivity of a givenpenetrant inspection process are the cleaning methods on the parts before the penetrant inspection, the selection ofpenetrant materials and the process by which the materials are used. This is not to be confused with "penetrant systemsensitivity level" which is a penetrant system classification term mentioned in paragraph 2.2.5 that will be furtherdiscussed in paragraph 2.4.4.3.
