The new national standard for noise limits of household appliances (GB/T 19606-2024) covers 19 categories of household appliances and will be officially implemented in September 2026

Time：

2026-09-11

GB/T 19606-2024 "Noise Limits for Household and Similar Electrical Appliances" specifies the noise limits, testing methods, and noise labeling requirements for household and similar electrical appliances, covering 19 major categories of household appliances. The standard specifies the market entry threshold and will officially come into effect on September 1, 2026. Products with excessive noise will not be legally sold in the market.

GB/T 19606-2024 "Noise limits for household and similar electrical appliances" will officially come into effect on September 1, 2026, replacing the GB 19606-2024 standard.

The nature of the standard has changed from mandatory to recommended in this revision, but the detailed rules on noise testing methods in the mandatory standard GB 44498-2024 "Health technical specification for household and similar electrical appliances" fully adopt GB/T 19606-2024. Furthermore, the corresponding noise limits in GB/T 19606-2024 fully adopt the values specified in GB 44498-2024. The two are closely linked and jointly regulate the noise of household electrical appliances.

A wide range of applicable products has been expanded

GB/T 19606-2024 covers the noise limit requirements and test methods for 19 categories of household electrical appliances, adding 13 categories of products based on the old version of the standard. The specific differences in product categories are shown in the table below:

GB 19606 - 2004 old version	GB/T 19606 - 2024 new version
refrigerator	Refrigeration equipment
air conditioner	Room air conditioner
washing machine	washing machine
microwave oven	microwave oven

/	air purifier
/	vacuum cleaner
/	dishwasher
/	Drum dryer
/	Electric Massager
/	Electric food processing equipment
/	hair dryer
/	Dry cleaning robot
/	Water dispenser treatment device

Detailed Explanation of Changes in Noise Limits and Testing Methods for 6 Types of Products in the New Standard

Changes in Limits and Test Methods for Refrigerating Appliances

(1) Changes in Limit Requirements:

GB 19606-2004 Old Version:

Requirements of the new version of GB/T 19606-2024 (citing GB 44498-2024):

Although the numerical noise limit remains unchanged, the classification boundary for product volume has increased from 250L to 300L, so the noise limit requirements for refrigeration appliances in the range of >250L and ≤300L have become stricter.

(2) Differences in Testing Methods:

Differentiating points	GB 19606-2004 old version	GB/T 19606-2024 New Edition
Test envelope surface	Simple rectangular envelope, with 4 measurement points around	Select based on the dimensions and installation method of the prototype: • 9 measurement points on the centered rectangular envelope surface • 6 measurement points on the wall-side rectangular envelope surface (or 10 measurement points, depending on the dimensions) • 10 measurement points on the hemispherical envelope surface
Test Status	Set to medium or moderately strong cold state	Refrigerator compartment 5℃, freezer compartment -22℃, measured temperature
test cycle	Test after running for at least 30 minutes	3 on-off cycles
computational method	Note: The average sound pressure level is the arithmetic mean	Note: The average sound pressure level is the logarithmic average

Changes in Limits and Test Methods for Air Conditioners

(1) Changes in limit requirements:

GB 19606-2004 Old Version:

GB/T 19606-2024 new version requirements (referencing GB 44498-2024) add limit requirements for sound power level:

Sound pressure level and sound power level are different parameters, which require special attention when labeling noise values. In addition, the new version has eliminated the 14~28kW classification, and the limit requirements within this range have become stricter.

(II) Differences in test methods:

The sound pressure level test method in the old version refers to GB/T 7725-2004, while the sound pressure level test method in the new version refers to GB/T 7725-2022. The new standard adds a sound power level test method (Annex A).

Changes in Limits and Test Methods for Washing Machines

(1) Changes in Limit Requirements:

GB 19606-2004 old version

New version requirements of GB/T 19606-2024 (referencing GB 44498-2024)

Washing machine sound power level

Washing: 62dB(A)

Dehydration: 72dB(A)

Washing machine (including the washing part of a washer-dryer and a spin dryer)

Washing: 62dB(A)

Spinning (declared maximum spin speed ≤1200r/min): 72dB(A)

Spinning (declared maximum spin speed >1200r/min): 76dB(A)

(2) Differences in Testing Methods:

Differentiating points	GB 19606-2004 old version	GB/T 19606-2024 New Edition
Test envelope surface	Simple rectangular envelope, with 4 measurement points around	6 measurement points on the rectangular envelope surface against the wall
Test Status	Rated washing and dehydration condition Load: A combination of sheets, shirts, tablecloths, and handkerchiefs specified by the standard	Standard test program, maximum dehydration speed Load: Towel combination specified by the standard
test cycle	Washing: No specific time specified Dehydration: Test after 3 minutes	Three standard procedures; if dehydration exceeds 3dB(A) in any two instances, three additional tests need to be added
computational method	Note: The average sound pressure level is the arithmetic mean	Note: The average sound pressure level is the logarithmic average

Changes in Limits and Test Methods for Microwave Ovens

Differentiating points	GB 19606-2004 old version	GB/T 19606-2024 New Edition
limit	Sound power level is 68dB(A)	Sound power level is 65dB(A)
Test envelope surface	Centered placement, 5 measurement points (points 1-5 in the figure)	Select based on the dimensions and installation method of the prototype: • 9 measurement points on the centered rectangular envelope surface • 6 measurement points on the wall-side rectangular envelope surface (or 10 measurement points, depending on the dimensions) • 10 measurement points on the hemispherical envelope surface
Test Status	Normal load, the highest microwave power level or combination microwave oven is tested respectively while running after operating for 1 min at the highest microwave power level and the highest grill function level.	Standard test load, for microwave function and all possible combination functions, measurement should start 2 minutes after the appliance is started and end before the water boils

Changes in Limits and Test Methods for Range Hoods

Changes in Limits and Test Methods for Electric Fans

(1) Changes in Limit Requirements

GB 19606-2004 Old Version:

Requirements of the new version of GB/T 19606-2024 (citing GB 44498-2024):

The limit values remain unchanged, and the new standard adds requirements for determining the noise limit values of oscillating fans and ceiling fans.

(2) Differences in Testing Methods:

Differentiating points	GB 19606-2004 old version	GB/T 19606-2024 New Edition
Test envelope surface	4 measurement points of hemispherical and global envelope surfaces	The wall fan uses a hemispherical surface with 10 measurement points for wall-mounted installation. Other devices use a centrally positioned rectangular hexahedron with 9 measurement points.
computational method	Note: Among the 4 measurement points of each electric fan, if the difference in sound pressure level between any two points is ≤5dB, the average sound pressure level can be calculated using the arithmetic mean; if the difference is >5dB, the logarithmic mean value shall be used for calculation.	Note: The average sound pressure level is the logarithmic average
