The General Administration of Quality Supervision, Inspection and Quarantine and China Standardization Committee revised the 2004 edition of Safety and Hygiene Requirements for Tableware Disinfectors, and issued a new national standard with the standard number GB 17988-2008 on February 3, 2008, with the implementation date of 20 10. The standard clearly stipulates the definition, scope of application, classification, series, signs and descriptions, physical and chemical properties, effect testing, safety and technical specifications of disinfection cabinets. According to Zhang Lizhong, director of the command center of the Municipal Administration for Industry and Commerce 123 15, the disinfection effect of disinfection cabinets (rooms) is divided into two grades: one star and two stars.

One-star disinfection standard: it can kill representative strains such as Escherichia coli. During ozone disinfection, the ozone concentration in the disinfection cabinet should be greater than or equal to 20mg, and the disinfection time should be greater than or equal to 30min. During high-temperature disinfection, the disinfection temperature in the disinfection cabinet should be greater than or equal to 100 degrees Celsius, and the disinfection time should be greater than or equal to 15 minutes.

Two-star disinfection standard: in addition to eliminating Escherichia coli, disinfection targets also include representative strains such as "poliovirus". During ozone disinfection, the ozone concentration in the disinfection cabinet should be greater than or equal to 40mg/m3, and the disinfection time should be greater than or equal to 60min; During high-temperature disinfection, the disinfection temperature in the disinfection cabinet should be greater than or equal to 120 degrees Celsius, and the disinfection time should be greater than or equal to 15 minutes.

The new national standard clearly stipulates in the section of "signs and instructions" that the disinfection level of the disinfection cabinet should be marked on the front of the disinfection cabinet to show different disinfection effects. The disinfection effect of at least one room in the disinfection cabinet should reach the order of magnitude. One-star disinfection cabinet (room) is marked with disinfection star "*"; The two-star disinfection cabinet (room) is marked with a disinfection star "* *". The "Disinfection Star" sign shall not be used in the disinfection room that does not reach the disinfection level of the disinfection cabinet, and the use function of the room shall be marked.
