India adds deep freezers to voluntary scheme of Standards & Labeling Programme. 
On March 5, 2020, India’s Bureau of Energy Efficiency (BEE) announced the addition of deep freezers to the voluntary list of products covered by the Standards & Labeling Programme. The programme covers deep freezers of top access type, basically the chest freezers having a storage volume up to and including 1000 liters, with both hard top and glass top (sliding, hinged and curved) and their rated voltage not exceeding 250 V ac 50 Hz for single phase and 415 V ac 50 Hz for three phase ac, as specified under the scope of IS 7872 with all amendments.
The star rating parameters as follows are used for determining Star Rating Bands for a particular model.
Star Rating Band (SRB) = Kdc * V+ Cdc
Kdc = Constant Multiplier (kWh/Liter/Year)
V = Storage Volume (Liter)
Cdc = Constant Fixed Allowance (kWh/Year)
Hard Top Chest Freezers
(Valid from April 1, 2020 to December 31, 2021)
| Star rating | Annual Energy Consumption (Et) in kWh/year at 38 ºC |
|---|---|
| 1 Star | 4.23*V + 126.65 ≤ AEC < 5.07*V + 151.98 |
| 2 Star | 3.52*V+ 105.54 ≤ AEC < 4.23*V + 126.65 |
| 3 Star | 2.82*V + 84.43 ≤ AEC < 3.52*V+ 105.54 |
| 4 Star | 2.25*V + 67.55 ≤ AEC < 2.82*V + 84.43 |
| 5 Star | AEC < 2.25*V + 67.55 |
Glass Top Chest Freezers
(Valid from April 1, 2020 to December 31, 2021)
| Star rating | Annual Energy Consumption (Et) in kWh/year at 38 ºC |
|---|---|
| 1 Star | 7.68*V + 511.17 ≤ AEC < 9.21*V + 613.40 |
| 2 Star | 6.40*V+ 425.97 ≤ AEC < 7.68*V + 511.17 |
| 3 Star | 5.12*V + 340.78 ≤ AEC < 6.40*V+ 425.97 |
| 4 Star | 4.09*V + 272.62 ≤ AEC < 5.12*V + 340.78 |
| 5 Star | AEC < 4.09*V + 272.62 |
