Microbial aerosol cabinets test the antibacterial and sterilizing performance of electrical appliances

Microbial aerosol cabinets, also known as microbial bacteria aerosol chambers, can be used to test the antibacterial and sterilizing ability of household appliances. In a container, certain techniques or methods (such as filtration, adsorption, degradation, etc.) A device that significantly reduces the concentration of particulate gaseous pollutants and microorganisms in the air.

Let's learn more about microbial aerosol cabinets:

A. The role of the microbial aerosol cabinet: It is mainly suitable for the evaluation test of the disinfection effect of the 1 cubic meter bacterial aerosol cabinet, and the sampler is a liquid impact sampler.

B. Manufacturer: Dongguan Ring Instrument

C. The microbial aerosol cabinet meets the standards:

GB/T 18883-2002 Indoor Air Quality Standard

GB 19258 Ultraviolet germicidal lamp

GB21551.1--2008 General rules for antibacterial, sterilization and purification functions of household and similar electrical appliances

GB21551.2-2010 Antibacterial of household and similar electrical appliances. Special requirements for antibacterial materials with sterilization and purification functions

WS/T 206 Determination method of inhalable particulate matter in the air of public places - light scattering method

"Technical Specifications for Disinfection" (Ministry of Health, 2002 edition)

D. Health and safety:

1. The equipment meets the relevant health and safety requirements in GB 21551. 1-2008.

2. The harmful substances produced by the equipment itself meet the national control indicators.

3. When inspecting the harmful factors that may be produced by the equipment itself, the laboratory test value minus the laboratory environment background concentration value shall be used as the test result value.

4. The concentration of volatile organic compounds (TVOC) at the air outlet of the equipment is tested by thermal desorption/capillary gas chromatography.

5. The inspection of PM10 particle concentration at the air outlet adopts the light scattering method specified in WS/T206.

E. The sterilization performance of the microbial aerosol cabinet should meet the following requirements:

1. The antibacterial (sterilization) rate is greater than or equal to 50% after running for 1 h under simulated field and field test conditions;

2. The antibacterial properties should meet the relevant requirements in GB 21551.2-2010.

3. Purification materials should be able to be replaced or regenerated, and purification devices should be able to be cleaned and disinfected.
