New Delhi, 4th August, 2025
S.O. 3582(E). In exercise of the powers conferred by clause (a) of section 14 of the Energy Conservation
Act, 2001 (52 of 2001), the Central Government in consultation with the Bureau of Energy Efficiency, hereby specifies
the following energy consumption standards for star labeled domestic liquefied petroleum gas stove for household use,
with effect from 1st January, 2026, namely:-
1. Every domestic liquefied petroleum gas stove for domestic cooking uses that works on liquid petroleum gas being
manufactured, imported, or sold in India shall meet the compliance requirements contained as per Indian Standard 4246:
2002;
2. Definitions: For the purposes of this notification, following definitions, in addition to those given in IS 6480: 2023,
shall apply:-
(a) domestic gas stove: the domestic gas stove means domestic gas burning appliance with metallic bodies with
or without toughened glass top, consisting of single or multiple burners, injector jets, gas taps, burner pan
supports, piping and fitting intended for use with liquefied petroleum gas at 30 grams-force per square
centimetre (gf/cm²) gas inlet pressure.
Note: Pressure regulator is not included.
(b) label: any written, printed, marked, stamped, or graphic information displayed on the domestic liquefied
petroleum gas stove;
(c) Label Period: The label validity period of the thermal efficiency standards as specified in the table 3.1.
(d) thermal efficiency: the thermal efficiency means that the domestic gas stoves using liquefied petroleum gas
shall be determined as per test procedure specified in "clause 26 of IS 4246: 2002" (as amended from time
to time);
3. Star rating or star level plan.- (1) The star rating or "star level" means the level of thermal efficiency on the label
of the domestic liquefied petroleum gas stove.
(2) The label to be affixed on domestic liquefied petroleum gas stove shall display between a minimum of one
and a maximum of five shown in one star interval.
(3) The star rating is calculated based on the thermal efficacy from the Star Rating Band as specified in the
following table 3.1, namely:-
(4) Every domestic liquefied petroleum gas stove shall refer to energy consumption standard which meets the
performance requirements as laid down in sub-paragraph (1) to (3) of this notification.
Table 3.1 Star Rating Plan for domestic liquefied petroleum gas stove
Validity (from 1st January, 2026 to 31st December, 2028)
+-------------+---------------------------------------+
| Star Levels | Thermal efficiency (As per IS4246: Latest) |
+-------------+---------------------------------------+
| 1 Star | ≥68% and <70% |
| 2 Star | ≥70% and <72% |
| 3 Star | ≥72% and <74% |
| 4 Star | ≥74% and <76% |
| 5 Star | ≥76% |
+-------------+---------------------------------------+
(5). The star level or star rating plan shall be reviewed after every two years or before the expiry of the table
validity period whichever is earlier.
4 Testing and tolerance.- (1) For the purpose of determining the star level of a domestic liquefied petroleum
gas stove, the following test shall be used as specified in the table 4.1 of this notification, namely:-
Table 4.1
+-------+-------------------+-----------------------------------------------------+
| S. No | Test parameters | Test Standards |
+-------+-------------------+-----------------------------------------------------+
| 1 | Thermal efficiency| clause 26 of IS 4246:2002(as amended from time to time) |
| 2 | Gas consumption | clause 17 of IS 4246:2002(as amended from time to time) |
+-------+-------------------+-----------------------------------------------------+
(2) There is no negative tolerance for the Star rating bands is applicable and all tested products must meet
the minimum value for each Star rating band.
(3) The scope for manufacturing tolerance and other variations shall be accounted by the manufacturer or
permittee while determining the Star Rating of a particular model.
5 ELIGIBILITY FOR PARTICIPATION,- (1) The manufacturers of equipment or importers or persons-in-
trade shall participate through standards and labeling portal in the scheme by registering with the Bureau;
(2) The appliance is suitable with only liquefied petroleum gas and not with any other family of gases.
(3) Valid Bureau of Indian Standards (BIS) certification marks licence for liquefied petroleum gas stove.
(4) The manufacturers are required to submit the test report as per IS 4246:2002(as amended from time to
time), which has been duly accredited by National Accreditation Board for Testing and Calibration
Laboratories or International Laboratory Accreditation Cooperation or Asia Pacific Accreditation
Cooperation or Council of Scientific & Industrial Research certified laboratory only.
6 Energy Efficiency Criteria- (1) The Thermal Efficiency of each burner of domestic liquefied petroleum gas
stove shall not be less than value specified in table 3.1 of this notifications for each star level.
(2) For domestic liquefied petroleum gas stove, the lowest thermal efficiency of a burner of the stove shall
be considered for Star labeling.
7 Test report,– (1) The results of the sample tested shall be reported on the prescribed format given in Annexure
- A of this notification.
(2) A test report for three numbers of samples of each domestic liquefied petroleum gas stove model is
required for registration;
(3) Thermal Efficiency of each burner of the domestic liquefied petroleum gas stove.
(4) Gas Consumption (kilogram) for all three samples.
8 Testing Procedure: The tests outlined in this notification shall be conducted according to IS 4246:2002(as
amended from time to time).
