Humidifier National Performance Standards
National performance standard
One is the amount of humidification. This is the most important parameter of the humidifier. Some enterprises cater to consumers' pursuit of large humidification, and arbitrarily mark the amount of humidification. Therefore, the standard strictly stipulates that the humidification amount should not be lower than the nominal value of the product's rated humidification amount.
The second is humidification efficiency. Refers to the ratio of the actual humidification amount of the humidifier to the input power, which reflects how much humidification the unit power consumption can produce. It is an important indicator to measure the performance of the humidifier. In order to guide consumers to purchase energy-saving and environmentally-friendly products and to promote the development of more efficient products, the standard is divided into four levels: A, B, C, and D.
The third is noise. Considering that the humidifier may be used in the bedroom, if the noise is too large, it will have a certain impact on the consumer, so the standard imposes strict limits on the noise index.
The fourth is the life of the evaporation core. For direct evaporative humidifiers, the evaporating core is the component that has the greatest impact on performance. As the humidifier continues to be used, the efficiency of the evaporating core will continue to decrease and the amount of humidification will continue to decrease. The standard stipulates that when the humidifier's humidification amount is reduced to 50% of the initial humidification amount, it is considered as the evaporation core failure. For replaceable evaporation cores, the service life should be no less than 1000 hours.
The fifth is that many humidifiers have auxiliary functions such as softened water and humidity display. In order to prevent certain products from obviously having this function, or this function can not achieve the corresponding effect, the consumers are misled by false propaganda. The standard also puts specific requirements on these auxiliary functions: for water softeners, the standard specifies that the hardness of water should not exceed 100 mg/L after softening by a water softener. Before the softener is deactivated, the total amount of softened water should not be less than 100L. For the humidity display, it is stipulated that the relative humidity should be within the range of 30% to 70%, and the humidity display error should be within ±10%, so as to avoid the error being too large and misleading to consumers. In addition, the standard also stipulates that since the water level will have a significant impact on the performance of some humidifiers, the humidifier should have a water level protection function to prevent consumers from ignoring the humidifier for a long time with low performance and low efficiency.
