T/NBWJ 05-2022 desktop cleaner

Scope

Main Technical Content: The main content and determination basis of this standard specify the classification, technical requirements, test methods, inspection rules, marking, packaging, transportation, and storage of desktop cleaners. The main technical content and determination basis are as follows: a) **Adsorption Force**: "It should be able to adsorb a 5g-weighted counterweight and not fall off within 60 seconds." Four brand products were verified, and the results are shown in the table below. The lightest adsorption weight was 4g. The corresponding products could successfully adsorb small debris such as rubber scraps, pencil shavings, and paper scraps, indicating normal cleaning performance. Considering the advanced nature of the standard, the adsorption force was set to 5g. Brand A Brand B Brand C Brand D Maximum Adsorption Weight 9g 5g 6g 4g b) **Adsorption Effect**: "During cleaning, surrounding debris should not be blown away, and no residual debris should remain after cleaning." The adsorption effect of desktop cleaners is a key function. It not only requires the ability to adsorb heavy debris during normal operation and clean small debris effectively, but also considers whether the airflow generated during operation might blow away debris around the cleaner, increasing cleaning difficulty. Therefore, this indicator was determined. c) **Blocking Protection**: "The product should be able to function normally after blocking for 30 seconds." During the initial drafting of the standard, it was considered that if long strips of hard objects or hair strands were inhaled during cleaning, the motor might overheat and cause damage, leading to safety hazards. Therefore, desktop cleaners should have an abnormal power-off function. In the initial draft of the standard, the technical indicator was set as "Blocking power-off time ≤ 30 seconds." However, based on market research, most enterprises, due to structural and cost considerations, do not
