Quiz on Non-Destructive testing Welcome to your Quiz on Non-Destructive testing 1. Which of the following is not Non-Destructive Testing method? Acoustic Emission Testing Radiographic Testing Ultrasonic Testing Magnetic Particle testing Liquid Penetrant Examination Charpy Testing None 2. Non-Destructive Testing method is used to evaluate material properties, Components or entire process units Detect, characterize or measure the presence of Damage Mechanisms Detects the size, shape & orientation of defect All of the above None 3. The purpose of NDT is to inspect a component in a safe, reliable & cost effective manner True False None 4. NDT helps in making informed decisions for remaining equipment life evaluations True False None 5. NDT inspections do not provide historical data on, how often a component should be inspected, repaired or replaced? True False None 6. Who prepares the NDT methods? American Society of Non-Destructive testing (ASNT) ASTM Internation (Americal Society of Testing Materials) ASME (American Society of Mechanical Engineers) API (Americal Petroleum Institute) All of the above None of the above None 7. Acoustic Emission Testing (AET) is a nondestructive testing (NDT) method True False None 8. Acoustic Emission Testing (AET) is a method that is based on the generation of waves produced by a sudden redistribution of stress in a material. True False None 9. Acoustic Emission Testing has following applications assessing structural integrity detecting flaws testing for leaks monitoring weld quality All of the above None 10. Acoustic Emission Testing detects creep damage in high energy piping (HEP) systems True False None 11. Acoustic Emission Testing systems generally contain a sensor, preamplifier, filter, and amplifier, Measurement, display, and storage equipment. All of the Above None 12. Liquid Penetrant Examination (LPE), is not a non-Destructive Testing True False None 13. Liquid Penetrant Examination (LPE) utilizes fluorescent dye to reveal surface flaws True False None 14. Liquid Penetrant Examination (LPE) is also known as penetrant testing (PT) liquid penetrant testing (LP) dye penetrant testing (DP) All of the above None 15. Working technique or the principle of Liquid Penetrant Examination (LPE) is “capillary action" True False None 16. Liquid Penetrant Examination (LPE) is one of the easiest and least expensive NDE techniques to perform True False None 17. there is no harm in using a longer penetrant dwell time in Liquid Penetrant Examination (LPE) as long as the penetrant is not allowed to dry True False None 18. Magnetic Particle Inspection, is a destructive examination (NDE) technique True False None 19. Magnetic Particle Inspection is used to detect surface and slightly subsurface flaws in iron nickel cobalt All of the above None 20. Magnetic Particle Inspection will create a “flux leakage field” at the site of the damage. True False None 21. Limitations of Magnetic Particle test The material must be ferromagnetic The method only detects surface and near-to-surface defects. Large currents are sometimes required to perform this method, that may cause burning of test part All of the above None 22. Radiographic Testing (RT) is a nondestructive examination (NDE) technique True False None 23. Radiographic Testing (RT) involves the use of either x-rays or gamma rays to view the internal structure of a componentinvolves the use of either x-rays or gamma rays to view the internal structure of a component True False None 24. Radiographic systems are portable, which allows for use in the field and at elevated positions. True False None 25. Radiography is an effective tool that requires very large surface preparation. True False None 26. Digital radiography require film True False None 27. Ultrasonic Testing (UT) is a group of nondestructive examination (NDE) techniques True False None 28. Digital Radiography allows for a much shorter exposure time so that the images can be interpreted more quickly. True False None 29. Radiography use short, high-frequency ultrasonic waves to identify flaws in a material. true False None 30. Most UT devices consist of Pulsers receivers Transducers Display monitors All of the above None 1 out of 15
