LIQUID PENETRANT LEVEL II ACTUAL EXAMS QUESTIONS WITH
COMPLETE VERIFIED ANSWERS BY EXPERT GRADED A++
Which of the following discontinuities could be classified as a finishing processing
discontinuity?
-Heat-treat crack
Aluminum alloy test specimens that have been tested by the liquid penetrant method
should be thoroughly cleaned after testing because:
-the alkaline content of wet developers and most emulsifiers could result in surface pitting,
particularly in moist atmospheres.
Which factor would apply in determining the dwell time required for the penetrant to be
effective?
-Type of discontinuity sought.
Which of the following physical properties, more than any other, determines what makes a
material a good penetrant?
-No one single property determines if a material will or will not be a good penetrant.
Which of the following discontinuities might be found in rolled plate?
-Laminations
Which of the following is NOT recommended method of removing grease from a surface of
a part to be penetrant tested?
-Hot water rinse
, Which of the following is NOT a form in which penetrant developer is commonly
available?
-High viscosity developer
When using post-emulsification penetrants, difficulties incurred during the washing
operation can be overcome by:
-completely reprocessing the part from surface preparation on and by using a longer emulsifier
time.
The function of the emulsifier in the post-emulsification penetrant method is to:
-react with the surface penetrant to make the penetrant water-washable.
Which of the following is a discontinuity that might be found in forging?
-Lap
Shrinkage cracks are usually found in what areas of a casting?
-Abrupt changes in thickness
Which of the following is an advantage of visible dye penetrants over fluorescent
penetrants?
-No special lighting is required.
Of the methods listed below, the most effective means of precleaning a test item prior to a
penetrant test is:
-vapor degreasing
Which of the following statements concerning contaminating materials on the surface of a
part to be penetrant tested is NOT true?
-The contaminant may retain the penetrant and thus increase the sensitivity of the inspection
