Champ d’application

This standard applies to household and similar refrigerators, including freezers and refrigerator-freezers, that possess antibacterial functions or deodorization devices. It specifies the hygiene requirements, testing methods, and marking for these appliances. This standard is mandatory for all manufacturers of antibacterial refrigerators entering the Chinese market. It should be used in conjunction with GB 21551.1-2008.

Exigences techniques

The standard outlines several mandatory technical requirements for antibacterial refrigerators. First, it sets hygiene safety and toxicological requirements, demanding that new materials pass acute oral toxicity, skin irritation, and eye irritation tests. Manufacturers must ensure all applied materials meet these strict toxicological limits. Regarding antibacterial performance, the standard requires that main components exhibit an antibacterial rate of ≥90% against Staphylococcus aureus and Escherichia coli after 18-24 hours of contact. For mold prevention, the materials must achieve a mold resistance grade of 0 to 1. For deodorization, the appliance must demonstrate an adsorption or decomposition rate of ≥90% for methyl mercaptan and trimethylamine. Additionally, the standard regulates hazardous substance leakage, specifying that ozone concentration and UV intensity around the unit must not exceed defined limits. The UV generating device must automatically stop when the refrigerator door is opened.

Méthodes d’essai

Testing methods include toxicological assessments conducted according to the Disinfection Technical Specification (2002). Material antibacterial performance is tested based on GB 21551.2-2010. For deodorization testing, specific gases are introduced into the sealed refrigerator, and residual concentrations are measured using gas chromatography methods referenced in GB/T 14678 and GB/T 14676. Hazardous substance leakage, such as ozone and UV intensity, is measured using specified photometric and disinfection standard procedures.
