What type of light is used with fluorescent penetrant inspection?
What type of light is used with fluorescent penetrant inspection?
ultraviolet light
What is the minimum visible light intensity required for examination using visible penetrant?
100 foot candles
What is the prerequisite for a penetrant test?
The PCN requirements for Penetrant Level 1 are: 16 hours training, previous to the exam, and 1 month supervised work experience, to be obtained either before the examination, or within 24 months after passing the exam.
Can UV light be created?
UV radiation is produced either by heating a body to an incandescent temperature, as is the case with solar UV, or by passing an electric current through a gas, usually vaporized mercury. The latter process is the mechanism whereby UV radiation is produced artificially.
Can a phone create UV light?
While no current smartphone is technically capable of emitting UV light, you can mimic the effect of a black light using your phone's LED flash, a few markers, and some transparent tape.

How do I choose a UV sterilizer?
The greater the UV power per unit of water, the better the sterilization effect; the greater the flow rate of the water through the UV lamp sterilizer, the greater the total sterilization effect; the greater the UV254 transmittance, the better the sterilization effect.Jul 7, 2020
What light bulb gives off the most UV?
UVB bulbs, also known as retile basking bulbs, emit substantially more UV rays than fluorescent or incandescent light bulbs, and are usually found in pet stores.Apr 13, 2018
What is the difference between a black light and an ultraviolet light?
In a nutshell, there isn't quite a difference, but a misunderstanding of the terms. Black light is nothing but UVA light, while UV light is basically composed out of UVA, UVB and UVC. So in other words, black light is UV light(450-100nm), covering the 400-320nm spectrum.Apr 28, 2017
What shows up under black light?
Thiamine, riboflavin, niacin, fluids and vitamins shine under black light. Urine, semen and blood contain fluorescent molecules, so they also show up under black light. Interestingly, some cleaners and laundry detergents, scorpions, tonic water and antifreeze and teeth whiteners all also glow under black light.
What do you use black light for?
Black lights are required to observe fluorescence, since other types of ultraviolet lamps emit visible light which drowns out the dim fluorescent glow. Black light is commonly used to authenticate oil paintings, antiques and banknotes.
