MEPS and Labelling for Electric rice cookers: TCVN 8252: 2009 (applied by 78/2013/QD-TTg)

Source: International Energy Agency
Last updated: 29 October 2019

This standard is adopted based on the title year, but only takes effect in the market based on the following laws:

    • Decision 51/2011/QD-TTg & Decision 03/2013/QD-TTg stipulates the list of equipment subject to energy labelling program, application of MEPS and the roadmap.
          1. For home appliances group: As of January 1, 2014, it is not allowed to import and produce devices with energy efficiency below the minimum energy efficiency.
          2. For industrial equipment, office equipment and commercial equipment: From January 1, 2015, it is not allowed to import and produce equipment with energy efficiency levels below the minimum energy efficiency.
          3. For round light products (incandescent lamps): From January 1, 2013, it is forbidden to import, produce and circulate lamps with a capacity of greater than 60 W.
    • Decision 78/2013/QD-TTg, stipulates the list of equipment and roadmap for rejecting lower than MEPS appliance/equipment
          1. For household appliances and industrial equipment: From January 1, 2015, it is not allowed to import and produce equipment with energy efficiency levels below the minimum energy efficiency.

 

Promulgated 25 December 2013.

 

MEPS shall not be less than 80% of R-actual

R-actual (%) = (dT * [ Q + (Wg1* Cp1) + (Wg2 * Cp1) ] * 100 ) / ( 0.24 * Ec * 3600 )

Q: weight of water in grams

Wg1: weight of the pot in grams, aluminium part

Wg2: weight of the pot, in grams, stainless steel part

Cp1 = 0.22 cal/g-K, specific heat capacity of aluminium

Cp2 = 0.12 cal/g-K, specific heat capacity of stainless steel

 

T1: initial temperature of water in the pot in degC

T2: final temperature of water in the pot in degC

dT = T2 – T1

Ec = power consumed in 240s of heating, in Wh

0.24 = specific heat constant

 

Comparative labelling is based on K = R-actual / R-min:

1-star: = 1.00

2-star: = 1.05

3-star: = 1.10

4-star: = 1.15

5-star: = 1.20

 

National standard TCVN 8252: 2009 for Electric rice cookers - Energy efficiency has been replaced by National standard TCVN 8252: 2015 for Electric rice cookers - Energy efficiency.
