greatest extent by which of the following properties?
Viscosity
Which of the statements concerning the operation of the ultraviolet light bulbs of
the mercury-arc type is false
Line voltage variations above 120v will have little or no effect on the bulb.
What is a disadvantage of using the liquid penetration test method
Method cannot find discontinuities that are sub-surface
What type of discontinuities can be classified as a primary processing
discontinuity, often found in cast material
Porosity
What Discontinuities can be classified as a finishing processing discontinuity
Heat treat crack
What discontinuity could be classified as a service induced discontinuity
Fatigue crack
What foreign matter might block openings of discontinuities
Paint, scale, core, and mold material
What method is not recommended to remove grease from test specimen
Hot water rinsing
The penetrant indication for a cold shut is?
Dotted or smooth continuous line
The penetrant indication of a forging lap will normally be a ?
Continuous line OR dotted line
, Spherical indications mean which type of discontinuity
porosity
Penetrant developer is available in all forms except ?
high viscosity developer
What is a possible cause for false penetrant indications
lint or dirt
Developer assist the detection of penetrants retained in discontinuities by aiding
the ?
bleed out process
Developer assist the detection of the visible dye penetrant test indications by ?
providing a back ground
When using post-emulsification penetrants, difficulties incurred in the washing
operation can be overcome by ?
Reprocessing the part and using a longer emulsifier time if allowed
How do you apply non-aqueous developer
spray method
What is the most effective pre-cleaning method to remove grease
Vapor degreasing
Fluorescent penetrants respond most actively to radient energy with a
wavelength of ?
365nm
Emulsifier time ?
