1. Irradiation Intensity and Effective Life Standards

Separate minimum initial irradiation intensity limits are set for different types of ultraviolet disinfection lamps, uniformly standardizing product service life determination criteria. It is clarified that the irradiation intensity retention rate at the end of lamp life shall not be less than 70% of the product's nominal value, effectively eliminating the industry chaos of products meeting standards in the early stage but failing in the later stage.

2. Spectral Purity Control

Spectral purity requirements are specifically set for special sterilization light sources such as 222nm excimer lamps, stipulating the proportion of effective sterilization band ultraviolet output, limiting ineffective long-wave radiation output, ensuring the real disinfection capacity of equipment, and preventing pseudo-compliant products from entering the market.

3. Ozone Safety Control

For ultraviolet disinfection products that generate ozone during operation, environmental ozone concentration safety thresholds are clearly set, strictly controlling ozone release to avoid human health hazards caused by excessive ozone.

4. Electrical and Usage Safety Protection

Improve safety indicators such as insulation performance, leakage prevention, and ultraviolet light leakage prevention of ultraviolet disinfection equipment, refine equipment installation, operation, and maintenance specifications, and clearly prohibit unattended usage scenarios in violation of regulations, avoiding equipment use safety risks from the source.

✅ Unified testing and labeling, transparent and traceable

The new standard unifies the testing methods, test conditions, and judgment basis for all categories of ultraviolet disinfection lamps, while mandating the product identification and labeling system. All ultraviolet disinfection products sold on the market must clearly label key compliance information on the body and instruction manual:

▪ Effective irradiation intensity and corresponding standard test distance
