Compliance overview
Scope and applicability
This standard applies to household and similar electrical air cleaners equipped with antibacterial and sterilization functions. All technical content in this standard is mandatory for manufacturers targeting the Chinese market. It specifically covers indoor air purification devices designed to reduce particulate matter, gaseous pollutants, and microorganisms.
Technical requirements
The standard specifies strict hygiene and safety requirements, mandating that air cleaners must comply with the general safety rules in GB 21551.1-2008. It sets maximum emission limits for harmful substances generated by the device itself, including ozone concentration, UV intensity, TVOC concentration, and PM10 concentration. Regarding functionality, The antibacterial rate must be greater than or equal to 50% after 1 hour of operation under both simulated and field test conditions. The antibacterial performance of the materials used must also meet the criteria specified in GB 21551.2-2010. Additionally, the purifying materials must be designed to be replaceable, regenerable, or cleanable. For labeling, products must clearly state their specific functions, technical indicators, and the replacement or regeneration cycle of the purifying materials in the user manual.
Testing methods
Testing for harmful emissions involves specific methodologies: ozone is tested via UV photometry (GB/T 18883-2002), UV leakage intensity per GB 19258, TVOC via thermal desorption/capillary gas chromatography, and PM10 concentration using the light scattering method (WS/T 206). The antibacterial performance is evaluated through a simulated field test in a 30m³ chamber using Staphylococcus albus 8032 as the test microorganism, calculating the natural decay rate and the device's sterilization efficiency.
FAQs
What products are regulated under GB 21551.3-2010?
It applies to household and similar electrical air cleaners that claim to have antibacterial, sterilization, or purification functions.
What is the minimum sterilization rate required by GB 21551.3-2010?
The air cleaner must achieve an antibacterial (sterilization) rate of at least 50% after operating for 1 hour in both simulated and field test conditions.
Does the standard limit harmful byproducts like ozone?
Yes, the standard sets strict limits on harmful substances generated by the air cleaner, including ozone (≤0.10 mg/m³), UV leakage (≤5 μW/cm²), TVOC (≤0.15 mg/m³), and PM10 (≤0.07 mg/m³).
