13. Gas Cooking Appliances

1) Target Scope:

Home cooking appliances that use gas as fuel. Equipment for industrial use, gas grills, gas cooking tables, gas rice cookers, portable gas stoves, and appliances using gases other than the gas group of city gas 13A group and liquefied petroleum gas as fuel are excluded.

2) Energy Consumption Efficiency:

Energy consumption efficiency (%) measured as specified by JIS S2103 for gas burner sections. For grill sections and oven sections, the energy consumption efficiency is gas consumption (Wh) consumed per one cooking.

3) Category and Target Values:

Burner Section

Category				Standard energy consumption efficiency
Gas cooking appliance type	Installation type	Number of burners	Category name	Standard energy consumption efficiency
Gas burners	Tabletop type		A	51.0
Gas burners	Built-in type		B	48.5
Vented type	Tabletop type	Less than 2	C	56.3
	Tabletop type	3 or more	D	52.4
	Built-in type	Less than 2	E	53.0
	Built-in type	3 or more	F	55.6
	Cabinet/stationary type		G	49.7
Gas range			H	48.4

Remarks:

A gas range is a combination of gas oven and gas burners.
Tabletop types are appliances used by placing on tables.
Built-in types are appliances set into a wall or table.
Cabinet types are appliance installed in specially-built cabinets.
Stationary types are appliance installed on a table or the floor.

Grill Section

Category			Grill Section Standard energy consumption efficiency calculation formulas
Combustion type	Cooking Method	Category name
Single Sided	With water	I	E=25.1Vg+123
Single Sided	Without water	J	E=25.1Vg+16.4
Double Sided	With water	K	E=12.5Vg+172
Double Sided	Without water	L	E=12.5Vg+101

Remarks:

E and Vg express the following numeric values.
E: grill section standard energy consumption efficiency (unit: Wh).
Vg: Internal volume (unit: l)
Internal volume is obtained by the formula: grill area × height from the bottom of the grill plate to the top of the inlet.

Oven Section

Category		Oven Section Standard energy consumption efficiency calculation formulas
Installation type	Category name
Tabletop type or stationary type	M	E=18.6Vo+306
Built-in type	N	E=18.6Vo+83.3

Remarks:

E and Vo express the following numeric values.
E: oven section standard energy consumption efficiency (unit: Wh). Vo: internal volume (unit: l)
Internal volume is obtained by the formula: internal bottom area × internal height

4) Target Fiscal Year:

Burner Section: 2006
Grill Section: 2008
Oven Section: 2008

5) Energy Conservation Effects:

Burner Section:: Approximately 13.9% improvement in efficiency compared to 2000 levels by 2006.
Grill Section:: Approximately 27.4% improvement in efficiency compared to 2002 levels by 2008.
Oven Section:: Approximately 20.3% improvement in efficiency compared to 2002 levels by 2008.

6) Display Items:

Product name or type, category, burner section energy consumption efficiency (limited to models with burner section/ grill section energy consumption efficiency (limited to those with grill section), manufacturer's name

7) Place of Display:

Catalogues and product bodies in which data on performance is shown. For appliances with burner section that have more than two burners, the heat efficiency of individual burners should be indicated respectively on catalogues in which performance data is shown.

8) Exemption:

Manufacturers or importers that ship less than 5,000 units in total are excluded, but display obligations must be met regardless of the number of units shipped.
