Compliance overview
Scope and applicability
This standard specifies the antibacterial and antifungal performance test methods and effect evaluation for antibacterial materials and components used in household and similar electrical appliances. It is applicable to antibacterial materials and related antibacterial components used in household appliances such as refrigerators, air conditioners, washing machines, and disinfection cabinets. This standard is mandatory for all manufacturers producing antibacterial appliances for the Chinese market.
Technical requirements
The standard classifies materials based on their antibacterial and antifungal properties. For antibacterial materials, the antibacterial rate must be greater than or equal to 90%, while also meeting the safety requirements specified in GB 21551.1-2008. For antifungal materials, the mold resistance grade must be either Grade 0 (no growth) or Grade 1 (trace growth, <10% coverage). For materials requiring both properties, both the 90% antibacterial rate and the Grade 0/1 mold resistance must be achieved simultaneously. Manufacturers must ensure their products meet these specific performance thresholds to claim antibacterial functionality. The standard also provides an informative appendix listing specific components in various appliances (e.g., refrigerator liners, washing machine tubs) that should possess these antibacterial properties.
Testing methods
The standard outlines three main testing methods: Test Method 1 (Film Covering Method) for non-water-absorbent materials and coatings, Test Method 2 (Absorption Method) for water-absorbent materials like non-woven fabrics and foams, and Test Method 3 for evaluating antifungal performance. These methods involve inoculating samples with specific bacteria (e.g., Staphylococcus aureus, Escherichia coli) or molds (e.g., Aspergillus niger), incubating them under controlled conditions, and calculating the antibacterial rate or observing the mold growth grade.
FAQs
What products are regulated under GB 21551.2-2010?
GB 21551.2-2010 applies to antibacterial materials and components used in household and similar electrical appliances, including refrigerators, air conditioners, washing machines, disinfection cabinets, vacuum cleaners, and water dispensers.
What is the minimum antibacterial rate required by this standard?
For a material to be classified as having an antibacterial effect, the antibacterial rate must be greater than or equal to 90%.
How is the antifungal performance evaluated?
Antifungal performance is evaluated based on a mold growth grade. A material is considered to have an antifungal effect if the mold growth grade is Grade 0 (no growth) or Grade 1 (trace growth, covering less than 10% of the surface).
