IR Class - ITC Level 1 Study Guide Exam
With Complete Solutions
What is the definition of certification - ANSWER Written testimony of
qualification
List two methods of re certifying as a Level I thermographer - ANSWER
take the test
retake the course
written documents or a certification course
How long is ITC's certification valid - ANSWER 5 years total
(start re-certifying at 4 years)
At what levels does ITC certify? ASNT? - ANSWER ANSI/ASNT CP-105
and ISO
ITC Levels 1,2, and 3 SNT-TC 1A and CP-105
What is the definition of thermography - ANSWER Process of the
acquisition and analysis of thermal information from non-contact thermal
imaging devices
What is the difference between night vision and infrared thermography -
ANSWER Night vision requires small amounts of visible light, and amplifies
it
Thermal cameras require no visible lights
, Outside, what is the coldest thing at which you can point your camera -
ANSWER the clear sky
Name the four benefits of using Infrared Thermography - ANSWER Non-
contact
Two dimentional
real time
passive
Does electronic or digital zooming, provided with many infrared cameras,
improve your ability to measure a small
target at a distance? - ANSWER No, does not improve resolution or
provide optical enhancement
For the majority of infrared cameras, what three image parameters cannot
be changed after an image has been
saved in digital format? - ANSWER FoRD
focus
range
distance
For the majority of infrared cameras, what image parameters can be
changed once an image is saved in digital
format - ANSWER emissivity, reflectivity, transmissivity, ambient temp.,
humidity, distance to target, color palette
What is meant by thermal tuning? - ANSWER manually adjusting the span
and level of the image to maximize thermal contrast on the target
and identify thermal gradients
What does a thermal gradient look like with an infrared camera? -
ANSWER a pattern that shows a gradual change in temperature over a
distance
What is the definition of a color alarm (a.k.a.: isotherm)? - ANSWER a
measurement tool that highlights an area of the same temperature or
thermal radiation
intensity with a color that is in contrast to the palette colors
