Air Purifier GB began to be revised

It is understood that at the amendment meeting of the national standards for air purifiers held on January 21, 2014, initial progress was made regarding the conversion coefficient of the applicable area and air cleanliness. This conversion factor is different from the standard of foreign air purifiers and is derived from the current ambient air quality in China. Lu Jianguo, secretary general of the National Household Electrical Appliances Standardization Technical Committee's Cleaning Appliances Subcommittee, revealed that the revision of GB/T18801-2008 "Air Purifier" is expected to be completed in the first half of 2014. The third draft has now been formed and is in the experimental verification stage.

Standard system: Relatively sound need revision

As the air purifier industry has attracted many companies to join in a short period of time, the quality of products has been mixed, and the topic of product standards has been repeatedly mentioned by the media. It is understood that there are currently six national air purifiers in China, namely GB/T18801-2008 "Air Purifier" and GB4706.45-2008 "Special Requirements for Safe Air Purifiers for Household and Similar Electrical Appliances." GB4706.1-2005 "Safety of household and similar electrical appliances Part 1: General requirements", GB21551.1-2008 "General requirements for antibacterial, sterilizing and decontamination of household and similar electrical appliances", GB21551.2-2010 "Home Special requirements for antibacterial, sterilizing and purifying functional antibacterial materials for similar electrical appliances, and GB21551.3-2010 "Special requirements for antibacterial, sterilizing and purifying air purifiers for household and similar electrical appliances". Among them, GB4706.45-2008 "Special requirements for safe air purifiers for household and similar electrical appliances" and GB21551.3-2010 "Special requirements for antibacterial, sterilizing and purifying air purifiers for household and similar electrical appliances", etc. Is a mandatory standard, GB/T18801-2008 "Air Purifier" is the recommended standard.

Among these standards, GB/T18801-2008 "Air Purifier" mainly assesses whether the air purifier has an effective purification capability, and sets technical requirements such as clean air volume (CADR), purification efficiency, noise, and purification life, and is a standard. Very important performance criteria within the system.

GB21551.3-2010 "Special requirements for air purifiers for antibacterial, bactericidal and decontamination functions of household and similar electrical appliances" mainly assesses whether an air purifier has an effective antibacterial and sterilizing capacity. Specific provisions include the antibacterial rate and sterilization. Rate and other technical requirements. Among them, the antibacterial rate is for the use of antibacterial materials, including anti-bacterial and anti-fungal evaluation requirements in two aspects; sterilization rate is for the entire machine technical requirements, highlights the air purifier as a household electrical appliances health care function, technical indicators are lower than Sanitary industry disinfection requirements.

Lu Jianguo indicated that the current national air purifier national standard system is relatively sound. The specific amendments to the GB/T18801-2008 “Air Purifier” mainly include the expansion of the air purifier's product range, the testing methods for harmful gases, and Bacteria method etc. It is reported that the new standard plans to include air conditioners with air-cleaning functions and car air purifiers. It is worth mentioning that with the GB4706.1-2005 "Safety Part 1 General Requirements for Household and Similar Electrical Appliances", a new round of revision work is started. GB4706.45-2008 "Safe Air Purification of Household and Similar Electrical Appliances" The revision of special requirements for the device is about to start. It is understood that GB4706.45 is adjusted with the adjustment of GB4706.1, so the content will not change much.

Revision direction: emphasis on operability

Lu Jianguo stressed that the revision of GB/T18801-2008 "Air Purifier" will be based on the status quo of air pollution in China and make a fuss about the operability and repeatability of standards. "The revised work of GB/T18801 should focus on operability within the acceptable range of air purifier manufacturers at home and abroad; in terms of repeatability, it should strive to achieve uniform test data in different laboratories, testing personnel and equipment. ."

The area of ​​application of air purifiers has recently been pushed to the cusp by the Shanghai Bureau of Quality and Technical Supervision. The formulation of product standards that meet the actual status of China's actual air quality and has practical operational guidance has not only become a consensus of the industry companies, but has also been finalized as an important content of the air purifier's national performance standard GB/T18801-2008 "Air Purifier". one.

In this regard, Lu Jianguo said that the revision of GB/T18801-2008 "Air Purifier" needs to consider the current status of major pollutants and air purifier manufacturers in China's air, from the perspective of consumers, to grasp the application of scientific development perspective Area and clean air volume conversion factor. "Revision of GB/T 18801 must take into account China's national conditions. When determining the relevant parameters and indicators, we do not recommend copying data from foreign air purifier standards. Only by doing so is it responsible to consumers."
