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).

Table 1 limit values of passive standby power, energy efficiency index and energy efficiency grades for colour televisions

Applicable time	content	Passive standby power（W）	Energy efficiency index
2006.3.1-2009.3.1	Limited value	9	1.5
2006.3.1-2009.3.1	Energy efficiency rating value	3	1.1
After 2009.3.1	Limited value	5	1.0
After 2009.3.1	Energy efficiency rating value	1	0.75

GB 24850-2010 stipulates the limit values of energy efficiency index and energy efficiency grades for flat panel televisions (see table 2 and table 3).

Table 2 limit values of energy efficiency index and energy efficiency grades for flat panel televisions

Energy efficiency index （EEI）	Energy efficiency grades
Energy efficiency index （EEI）	Grade 1	Grade 2	Grade 3
LCD TV energy efficiency index （EEI_LCD）	1.4	1.0	0.60
Plasma TV energy efficiency index （EEI_PDP）	1.2	1.0	0.60

Table 3 limit values of passive standby power for flat panel televisions

Effective time	Before 2012.1.1	After 2012.1.1
Passive standby power/W	≤1.0	≤0.50

GB 25957-2010 stipulates the limit values of passive standby power, energy efficiency index and energy efficiency grades for digital television receiver (set-top box) (see table 4).

Table 4 limit values of passive standby power, energy efficiency index and energy efficiency grades for digital television receiver (set-top box)

Types of receiver	Energy efficiency grades
	Grade 1		Grade 2		Grade 3
	On mode P_on	Passive standby power P_sp	On mode P_on	Passive standby power P_sp	On mode P_on	Passive standby power P_sp
Cable receiver	5.0+∑P_fa	1.0	7.0+∑P_fa	2.0	10.0+∑P_fa	3.0
Ground receiver	5.0+∑P_fa	1.0	7.0+∑P_fa	2.0	10.0+∑P_fa	3.0
Satellite receiver	7.0+∑P_fa	1.0	9.0+∑P_fa	2.0	12.0+∑P_fa	3.0
