                                               1. Nature of the defect


                                               2. Health and safety precautions
            The nature of the defect can have a large effect on
            sensitivity of a liquid penetrant inspection.





            What is sensitivity?

            Sensitivity is defined as the smallest defect that can be


            detected with a high degree of reliability. Typically, the crack

            length at the sample surface is used to define size of the

            defect.
