Malaysia sets MEPS for microwave ovens and electric rice cookers 
Guidelines regarding Minimum Energy Performance Standards (MEPS) for microwave ovens and electric rice cookers were released in Malaysia. Both guidelines prescribe the definitions of target products, MEPS, energy efficiency label standards, testing standards, etc.

Microwave oven
The formula for calculating the efficiency (η) of microwave ovens is as follows.
| Pt: Power consumption
Win: Energy required to heat up the magnetron filame |
The following two must be referred to for testing the efficiency.
-
- MS IEC 62301:2012 Household electrical appliances – Measurement of standby power
- IEC 60705:2010 Household microwave ovens – Methods for measuring performance
The rating of energy efficiency labels is evaluated by 5 stars, and the corresponding efficiency is shown in the table below. 2-star in the table below is set as MEPS.
|
Star rating |
Efficiency |
|
5-star |
65% ≤ η |
|
4-star |
58% ≤ η < 65% |
|
3-star |
53% ≤ η < 58% |
|
2-star |
45% ≤ η < 53% |
| 1-star |
η < 45% |
The design for the labels is as shown in the figure below.
Electric rice cooker
The formula for calculating the efficiency (η) of electric rice cookers is as follows.
| The volume of water before test (G)
The initial water temperature before test (T1) The highest water temperature after test (T2) Energy consumption (E) (unit: Wh) |
The following must be referred to for testing the efficiency.

- MS 2024:2020 Electric Rice Cooker for household use – Method of measuring the performance
The rating of energy efficiency labels is evaluated by 5 stars, and the efficiency corresponding to the rated power (P, unit: W) is shown in the table below. 2-star in the table below is set as MEPS.
| Star rating |

| 5-star | 85% ≤ η | 87% ≤ η | 89% ≤ η | 91% ≤ η | 93% ≤ η |
| 4-star | 80% ≤ η | 81% ≤ η | 82% ≤ η | 83% ≤ η | 84% ≤ η |
| 3-star | 75% ≤ η | 76% ≤ η | 77% ≤ η | 78% ≤ η | 79% ≤ η |
| 2-star | 70% ≤ η | 71% ≤ η | 72% ≤ η | 73% ≤ η | 74% ≤ η |
| 1-star | 65% ≤ η | 66% ≤ η | 67% ≤ η | 68% ≤ η | 69% ≤ η |
The design for the labels is the same as that of microwave ovens.
