Universal test methods of gas burning appliances for
domestic use
1 Scope
This Standard specifies terms and definitions of gas burning appliances, test conditions,
test gas and test methods for general performance.
This Standard is applicable to various gas water heaters, heaters, hot water heating
stoves, cooking utensils, ovens, oven stoves and rice cookers for household use.
The gas referred to in this Standard is the gas specified in GB/T 13611. The domestic
gas appliances that use gas types other than those specified in GB/T 13611 can refer to
this Standard.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1 reference conditions
the dry gas state under the conditions that the temperature is 15°C and the absolute
pressure is 101.3kPa
3.2 standard conditions
the dry gas state under the conditions that the temperature is 0°C and the absolute
pressure is 101.3kPa
3.3 nominal heat flow rate; rated heat input
under the rated gas pressure, the heat released by the burning appliance using the
reference gas per unit time
[CJ/T 3085-1999, definition 7.2.15]
3.4 converted actual heat rate
under the test conditions, the heat flow of the burner when using the test gas is converted
to the value under the reference conditions
4 Test conditions
4.1 Laboratory conditions
When there are no special provisions for laboratory conditions for each inspection item
or standard for burning appliances in this Standard, the following provisions shall be
followed:
a) Laboratory temperature: 20℃ ± 5℃;
b) Atmospheric pressure: 86kPa~106kPa;
c) Ambient air in the laboratory: the carbon monoxide content is less than 0.002%,
and the carbon dioxide content is less than 0.2%. There shall be no airflow
affecting combustion.
NOTE 1: The humidity requirements of the laboratory during the electrical test refer to the
provisions of GB/T 2421.
NOTE 2: How to determine room temperature: In front of the burning appliance, 1m on the left and
right, fix the temperature-sensing part of the thermometer at a position roughly the same height as
the upper end of the burning appliance. Measure the temperature of the above three points. The
average value is the room temperature.
4.2 Installation and test state of burning appliances
The installation of burning appliances shall be carried out in accordance with the
inspection items of this Standard or the provisions of each standard of burning
appliances.
Use a burner with adjustable air volume. At the beginning of the test, the air regulator
shall be adjusted to an appropriate opening. And it shall not be adjusted again during
the test.
4.3 Power supply conditions
The power supply conditions for the test shall meet the following requirements:
4.3.1 Burning appliances that use commercial power
appliance.
7.2 Open the first sealing valve at the gas inlet of the burning appliance. Close the
second sealing valve at the gas inlet of the burning appliance. At the gas inlet of the
burning appliance, use 4.2kPa air to test the air tightness of the second sealing valve in
the burning appliance.
7.3 Use "0-1" gas to ignite all burning appliances. From the first sealing valve at the
gas inlet of the burning appliance to the burning appliance port, use leak detection fluid
to test the external air tightness.
8 Burning condition test
8.1 The state of the burning appliance and the condition of the test gas during the
burning condition test of the burning appliance shall comply with the provisions in
Table 2.
For burning appliances using commercial power, the voltage condition shall be 220V.
8.2 Test method for burning conditions
8.2.1 Flame pass: After igniting a fire hole of the main ...
