Use of ultraviolet germicidal lamp should be in 3 ~ 6 months with ultraviolet radiation intensity of illumination apparatus for a test, using ultraviolet radiation intensity of illumination apparatus as a measurement calibration, to maintain the accuracy and found that the intensity of unqualified tubes to change in time. With our chemical indicator card detection methods to detect, 1, open the uv lamp 5 minutes later, the chemical card on vertical distance 1 m under uv light, chemical indicator CARDS patterned side up; 2, uv lamp irradiation for 1 minute, Chemical card will have different color changes) ; 3, the color of indicator card and compare it with the standard color piece, and then read the irradiation intensity. The testing results of the 10 w, for example: 1, the new uv germicidal lamp uv illumination not less than 30 uw/cm for qualified; 2, if is the use of ultraviolet lamp shall be not less than 20 uw/cm for qualified.
