Abstract: As consumers' demand for convenient cleaning of kitchen appliances continues to increase, the easy-cleaning performance of range hoods has become one of the key indicators for evaluating product quality. The release of T/CAS 1066.2—2025 " Specification for evaluation of surface easy cleaning performance of household and similar kitchen appliances—Part 2: Range hood" has established a systematic evaluation system for the surface easy-cleaning performance of range hoods for the first time. In order to deeply analyze the technical content of this standard and assess its guiding significance for industry technological progress, focused on the core requirements for the surface easy-cleaning performance of range hoods, and systematically elaborated the corresponding test methods and evaluation indicators from three dimensions: easy-cleaning property of material surfaces, easy-cleaning property of detachable parts, and easy-cleaning property under cooking environments. The standard specifies technical requirements and quantitative evaluation bases for various performances, providing actionable testing pathways for improving the easy-cleaning performance of range hoods. The result concluded that the establishment of this evaluation system plays an important guiding role in directing enterprises to optimize product design and promoting industry technological progress.
