Abstract: :Ultraviolet has a very good killing effect on bacteria, viruses and other microorganisms. It can destroy the molecular structure of DNA or RNA in the cells of microorganisms, and make the cells or regenerated cells die, so as to achieve the effect of sterilization and disinfection. UV disinfection lamp is widely used in more and more fields, especially in the sterilization of air and water, as well as the sterilization of object surface. Bacteria are more likely to grow in dark, humid, crowded and poorly ventilated conditions, resulting in cross infection, so ultraviolet disinfection lamps are widely used as disinfection equipment in daily household, public places, medical places and other special fields. This paper mainly interprets the relevant test methods and standards of UV disinfection lamp, aiming to introduce the quality requirements and evaluation methods of UV disinfection lamp.

Key words: Ultraviolet disinfection lamp, Sterilization, Evaluation method
