Scope: This document specifies the terms and definitions, general principles, technical requirements, material requirements, evaluation and labeling of rare earth dual-state antibacterial and epidemic prevention technologies. This document applies to non-medical epidemic prevention and control technology requirements and antibacterial and epidemic prevention grade evaluation. Other infectious diseases transmitted through environmental surfaces and indoor air can be referred to for use in their elimination and prevention; Main technical content: 5.1 Static antibacterial technology requirements: After the environmental surfaces are coated or covered with rare earth antibacterial materials, the static antibacterial technical indicators on the material surface are shown in Table 1. Table 1: Static antibacterial technical indicators Project | Virus inhibition rate (%) | Antibacterial rate (%) | Safety a | SARS-COV-2 virus (WIVO4, GenBank: MN996528.1), with the test method being the novel coronavirus plaque inhibition method. a | Test strains and their numbers include Staphylococcus aureus (ATCC 6538), Escherichia coli (8099), and Candida albicans (ATCC 10231). The film-coating test method is performed according to Chapter 5.2.6 of the "Evaluation Methods for Antibacterial and Bacteriostatic Effects" (WS/T 650-2019). c | The toxicological test method for Class I disinfection products is performed according to Chapter 1.4.3.2 of the "Disinfection Technical Specifications". 5.2 Dynamic disinfection and purification technology requirements: After the ionic disinfection and purification equipment is installed and operated in the indoor environment, the technical indicators for dynamic disinfection and purification of the air within the effective coverage physical space are shown in Table 2.
