ASNT Level II Study Guide
A lumen is defined as - ANS-equal to one fc falling on 1 ft2 of region
A photometer used by inspectors - ANS-converts radiant energy of light into measurable
electrical signal
Battery drain, lined chips, and high light intensities are all considerations while the use of -
ANS-LED resources
Being aware about dangers or risk associated with a drawing close inspection need to be part of
__________ making plans - ANS-safety
Decreasing the angle between the light source and the road of sight is useful when inspecting
_______ surfaces - ANS-tough
During direct visible inspection, viewing distance shall now not be any extra than - ANS-24 in or
610 mm
Environmental factors that affect visual inspection consists of - ANS-ecosystem and cleanliness
Eye muscle fatigue is pushed through - ANS-awkward frame positions and negative lights
How can glare be decreased during inspection of a part - ANS-Dimming the mild source
If the focus of the mild coming into the attention falls in front of the retina, the end result is -
ANS-myopia (neat-sightedness)
In a ordinary, healthy eye, the incoming light is targeted on the - ANS-retina
Luminous depth - ANS-is inversely proportional to the square of the gap from the source
Mill scale, weld slag, and floor coatings can probably - ANS-mask discontinuities
Operator performance, when visual trying out, is most tormented by - ANS-environmental
situations
The issue of the attention that responds to mild depth and gives the eye its shade is the -
ANS-iris
