Energy efficiency standards

時(shí)間: 2020-10-21

To accomplish the energy conservation and promote sustainable economic development, energy efficiency standards regulate the level of energy utilization rate for Energy-using Products. Therefore, the energy efficiency standards are the major technical basis for the implementation of national energy policy. At the current stage, there are 3 energy efficiency standards about audio and video products in China: GB 12021.7-2005 (Minimum allowable values of energy efficiency and energy efficiency grades for colour televisions), GB 24850-2010 (Minimum allowable values of energy efficiency and energy efficiency grades for flat panel televisions), and GB 25957-2010 (Minimum allowable values of energy efficiency and energy efficiency grades for digital television set-top box).
 
GB 12021.7-2005 stipulates the limit values of passive standby power, energy efficiency index and energy efficiency grades for colour televisions (see table 1).
