Black light is comonly used to refer to the UVA (UV band A light), this is from 315nm to 400nm, wich is the used for the fluorescent tests (with the peak in 365nm, that is the wavelenght that allows the fluorescence fenomenum) ----------- Start Original Message ----------- : I enterd my company NDT exam and I faced question I couldnt give answer for it regarding dye pentrant for aviation ?
