この概要は現在英語のみで提供しています。

適用範囲

This standard applies to ozone disinfectors that generate ozone via dielectric barrier discharge, ultraviolet irradiation, and electrolysis. It is applicable to equipment used for the disinfection of air, water, tableware, food processing pipelines, medical devices, medical supplies, and object surfaces. It does not cover ozone generators used solely for industrial processing rather than disinfection.

技術要求

The standard specifies comprehensive raw material requirements for ozone generation units, ensuring that components in contact with ozone are made of ozone-resistant materials. It mandates specific requirements for gas-water mixing devices and monitoring devices, including the need for ozone concentration monitoring to prevent leakage in occupied spaces. For technical performance, the standard categorizes requirements based on the ozone generation method (dielectric barrier discharge, UV, or electrolysis). It outlines limits for ozone concentration, production capacity, and power consumption. Additionally, it sets strict limits on byproducts such as nitrogen oxides and bromate, as well as maximum allowable limits for ozone leakage and residual amounts. The standard defines specific disinfection efficacy requirements based on the target object (e.g., air, water, medical instruments). It requires achieving specific kill rates or log reductions for indicator microorganisms like Staphylococcus aureus and Poliovirus-I. Manufacturers must ensure their equipment meets these mandatory microbial kill parameters to be compliant.

試験方法

Testing methods include the determination of ozone concentration using the iodometric method (chemical titration) or instrumental methods like UV absorption and electrochemical detection. Ozone production is calculated by multiplying the ozone concentration by the total inlet gas volume, while power consumption is measured using calibrated electrical meters. Disinfection efficacy is evaluated through laboratory, simulated field, and field tests according to the Technical Standard for Disinfection (2002) and other referenced GB standards.

よくある質問

What products are regulated under GB 28232-2020?

GB 28232-2020 regulates ozone disinfectors that generate ozone via dielectric barrier discharge, ultraviolet irradiation, or electrolysis, used for disinfecting air, water, medical devices, and surfaces.

Are there any updates from the previous version of GB 28232-2020?

Yes, compared to GB 28232-2011, the 2020 version restructured the technical requirements, added raw material requirements, expanded the application scope to include tableware and medical devices, and updated the testing methods.

How does GB 28232-2020 handle ozone leakage and residuals?

The standard sets strict mandatory limits for ozone leakage in occupied spaces and residual ozone in enclosed environments after a disinfection cycle to ensure user safety.
