National standard Minimum allowable values of energy efficiency and energy efficiency grades for flat panel televisions and set-top boxes, numbered GB 24850-2020 was released by State Administration for Market Regulation on April 22 2020. The standard is a combination and revision of GB 24850-2013 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 adapters (set-top boxes).
The standard is scheduled to take effect starting August 1 2021. It raises the bar for the energy efficiency evaluation of 4K (or lower definition) and flat-panel TVs and set-top boxes, and sets up energy efficiency requirements for 8K TVs.
