SKIT_NDT_DPI

Which developer form is used for dry powder developer?

• Form a

• Form b

• Form c

• Form d

A penetrant must:

• Change viscosity in order to spread over the surface of the part

• Spread easily over the surface of the material

• Have a low flash point

• Be able to change color in order to fluoresce

  
  

Application of the emulsifier should not be performed with a:

• Spray

• Brush

• Dip

• Both A and B

White light intensity at the surface of the part when using a visible dye penetrant should be:

• A minimum of 50 foot-candles

• A maximum of 50 foot-candles

• A maximum of 100 foot-candles

• A minimum of 100 foot-candles

Developers come in a variety of forms and can be applied by:

• Dusting

• Dipping

• Spraying

• All of the above

Raising the temperature will:

• Raise the speed of evaporation of penetrants

• Reduce the emulsifier time

• Increase the developer time

• Require the need of a post emulsified penetrant

When a permanent record is required which type of developer can be used:

• Lacquer developer

• Nonaqueous developer

• Layered developer

• Peeling developer

Which method of penetrant removal is post emulsified, hydrophilic?

• Method A

• Method B

• Method C

• Method D

Nonaqeous developer is typically applied:

• By dusting the surface of the part

• By dipping the part is a mixed batch of developer

• By splashing the surface with a brush

• By aerosol spraying

Which level of penetrant is the most sensitive?

• Level I

• Level II

• Level III

• Level IV
