Which process contains penetrants that are either self-emulsifying
or removable with plain water? [ANS:] Water-washable
Process that requires a separate emulsifier to make the penetrant
Guru01 - Stuvia
water washable [ANS:] Post-Emulsified Penetrants
Method where penetrants must be removed with a solvent which
is typical when using visible dye in pressurized spray cans. [ANS:]
Solvent-removable penetrants
Penetrant testing is limited by its inability to test materials that have
what types of discontinuities? [ANS:] Continuities that:
-Are not open to the surface
-Have an extremely porous surface
This cleaning method is particularly effective in the removal of oil,
grease, and similar organic contamination. [ANS:] Vapor

This cleaning method is effective for use on articles that have
been ground or machined. This process uses an acid or an
alkaline solution to open up grinding burrs and remove metal from
surface discontinuities. [ANS:] Etching
Contain an emulsifying agent which makes them easily
removable by a water rinse or wash. This penetrant material can
be obtained with either a visible or fluorescent dye. [ANS:] Water-
washable penetrants
Highly penetrating, oily visible or fluorescent penetrants which are

not soluble in water. [ANS:] Post-emulsifiable penetrants
Oily penetrants that do not contain an emulsifying agent [ANS:]
Solvent-removable penetrants
Guru01 - Stuvia
When applied to a penetrant-coated specimen, make the
resultant mixture removable by water rinse or wash. (they have
low penetrant characteristics) [ANS:] Emulsifiers
A fluffy, absorbent white powder, that is used in both fluorescent
and visible dye penetrant tests. [ANS:] Dry developers
type of developer where the developer powder is mixed with a
rapid-drying liquid solvent [ANS:] Non-aqueous wet developer
Must be used when articles inspected are subjected to contact
with either liquid or gaseous oxygen. [ANS:] Liquid oxygen (LOX)
compatible materials
Liquid penetrant place on the surface of a specimen does not
merely seep into discontinuities, it is pulled into them by what?
[ANS:] Capillary action

What are some methods of penetrant application? [ANS:]
Spraying
Brushing
Immersion
Pouring
The period of time during which the penetrant is permitted to
remain on the specimen [ANS:] Dwell Time

Which penetrant is preferred for use on articles with a rough
surface or one that contains threads or keyways? [ANS:] Water-
washable penetrant
Guru01 - Stuvia
What is the main disadvantage of water-washable penetrants?
[ANS:] Poor reliability in detecting wide or shallow discontinuities
Which penetrant method is difficult to use on rough surfaces, such
as cast magnesium? [ANS:] Solvent removable penetrant
This penetrant has a very high sensitivity for very fine
discontinuities, but is difficult to remove from threads, keyways,
blind holes, and rough surfaces [ANS:] Post-emulsification
The use of liquid penetrant in this method is suited for finding leaks
in such articles as tanks, piping, tubing, and hollow castings. [ANS:]
Leak-through technique
The temperature of the oven should not exceed ______ Degrees F,
as this could evaporate penetrant in the discontinuity [ANS:] 225
Degrees Fahrenheit
