3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
ultraviolet lamp
special electric light source directly using ultraviolet ray for disinfection
3.2
ultraviolet disinfection
disinfection method which is used to kill pathogenic microorganisms by making use of the principle that the genetic material of the pathogenic microorganisms that absorb the ultraviolet energy with a wavelength between 200nm~280nm will mutate and cause the cells to stop dividing and reproducing
3.3
ultraviolet appliance of disinfection
device that uses an ultraviolet lamp as the light source and ultraviolet ray emitted by the lamp as the sterilizing agent to disinfect pathogenic microorganisms on the transmission medium
3.4
ultraviolet appliance for air disinfection
ultraviolet appliance of disinfection that uses the combination of ultraviolet lamps, filter screen, fans and ballasts for air disinfection
Note: The filter screen and fan do not have the function of sterilizing agent.
