Which of the following defect is not detected by dye penetrant test?(a

1.	Which of the following defect is not detected by dye penetrant test?(a) Non-metallic inclusions(b) Leaks(c) Cracks(d) Forging defectsI had been asked this question in an interview.I would like to ask this question from Dye Penetrant Test in portion Non Destructive Techniques of Casting-Forming-Welding II
Answer» Correct answer is (a) Non-metallic inclusions Explanation: Dye penetrant test is ONE of the METHODS of non-destructive testing of the COMPONENTS. LEAKS, cracks and forging defects are some defects which can be identified by using dye penetrant test. But, for detecting non-metallic inclusions, one will have to do a MAGNAFLUX test.
