The standard applies to chemical disinfectants used via aerosol spray, fumigation, or gas disinfection methods. It does not apply to air purifiers without chemical disinfectants.

Exigences techniques

GB 27948-2020 outlines comprehensive mandatory technical requirements for air disinfectants. Firstly, it specifies raw material requirements, stating that peroxide and chlorine dioxide disinfectants must comply with their respective national standards. Secondly, it sets physicochemical parameters for active ingredient content, pH value, and stability. Manufacturers must ensure their products meet the strict microbial kill rates specified in laboratory and field tests. Thirdly, the standard introduces new safety requirements, including acute oral and inhalation toxicity limits, mutagenicity tests, and a newly added metal corrosion test. Products must clearly state their corrosion rating on the packaging. Finally, it mandates that labels and manuals must specify that the product is only for use in unoccupied spaces.

Méthodes d’essai

The standard references the Disinfection Technical Specification (2002 Edition) for evaluating disinfection efficacy and toxicological safety. Key testing procedures include the neutralizer identification test (detailed in Appendix A) for both liquid impinger and six-stage sieve air samplers. Additionally, the newly introduced metal corrosion test (Appendix B) requires evaluating corrosion rates on materials like carbon steel, aluminum, copper, and stainless steel using specific aerosol chambers.
