一、Introduction to Certification

Energy Efficiency Index (Energy Efficiency Index) is a classification method that indicates the energy efficiency of household appliances. According to relevant national standards, China's energy efficiency label divides energy efficiency into five levels. Level 1 indicates that the product's power saving has reached the international advanced level, with the lowest energy consumption; Level 2 indicates that the product is relatively energy-saving; Level 3 indicates that the product energy efficiency is the average level of the Chinese market; Level 4 indicates that the product energy efficiency is lower than the market average; Level 5 is the product market access index. Products below this level are not allowed to be produced or sold.
