GB 24850-2020 Active

This standard specifies the energy efficiency grades, energy efficiency limits, energy efficiency calculation, and testing methods for flat-panel televisions and general-purpose set-top boxes (also known as "digital television receivers"). This standard applies to LCD and OLED televisions (hereinafter collectively referred to as "flat-panel televisions") that operate normally under AC 220 V, 50 Hz power supply conditions and primarily function in receiving, demodulating, and displaying terrestrial, cable, satellite, or other analog and digital signals. It also applies to LCD and OLED display devices primarily used for television, which do not have tuners but are marketed as television products. This standard applies to set-top boxes that operate normally under AC 220 V, 50 Hz power supply conditions, including cable set-top boxes, terrestrial set-top boxes, satellite set-top boxes, and network set-top boxes. This standard does not apply to live satellite set-top boxes.
