One disadvantage of liquid penetrant testing is that: - ✔✔Penetrant materials may cause skin irritation
The removal of smeared metal by chemical processes is called: - ✔✔Etching
A liquid penetrant test cannot find: - ✔✔An internal cavity
Which of the methods is most applicable for detecting fine, tight surface cracks? - ✔✔Fluorescent,
postemulsifiable
The term used to describe the total time that penetrant remains on the workpiece is: - ✔✔Dwell
Developer assists in the detection of discontinuities by: - ✔✔Providing a contrasting background
Difficulties with removal of a postemulsifiable penetrant during the rinse operation can be overcome by:
- ✔✔Cleaning, then completely reprocessing the part using a longer emulsification time
Excessive removal of penetrant may result in: - ✔✔Undetected discontinuities during evaluation
Which of the following is an advantage of a fluorescent water-washable penetrant system compared to a
fluorescent postemulsifiable penetrant system? - ✔✔Water-washable has fewer processing steps
Which of the following is not an advantage of postemulsifiable fluorescent penetrants? - ✔✔They are
easily removed from sand castings after proper emulsification dwell time
, When using the visible, solvent-removable process, after the penetrant dwell time, excess penetrant is
removed by: - ✔✔Wiping off excess penetrant with a clean, dry cloth or paper towel; moistening a clean
cloth with solvent; and rewiping the part
When using a fluorescent, postemulsifiable penetrant, the best emulsification time is: - ✔✔Determined
by experimentation
Which of the following penetrant systems would not be recommended for the detection of small
discontinuities in aerospace critical parts? - ✔✔Visible, solvent-removable
Prerinse and post-rinse stations are necessary when using which of the following penetrant methods? -
✔✔Fluorescent, hydrophilic postemulsifiable
Processing a part with the presence of surface contaminants remaining from a previous machining
operation may result in: - ✔✔An increased chance of masking indications
Which of the following would not be the cause of a nonrelevant indication? - ✔✔A corrosion crack
Which of the following is a nonrelevant indication found during liquid penetrant testing? - ✔✔Penetrant
bleedout from a press-fit insert ring in the bore of a shaft
Ultraviolet light over a fluorescent penetrant wash station is used to: - ✔✔Monitor the removal of
surface penetrant
Which of the following is not a physical property associated with penetrant materials? - ✔✔Solvent
resistance
A standard classification for a type of developer is: - ✔✔Water-soluble
Which type of developer is generally considered the most sensitive for location fine discontinuities? -
✔✔Solvent-suspended
