Appendix C
(normative)
Noise limit value for washing machines
C.1 Scope
This Standard is applicable to household and similar electric washing machine
(including dehydrator).
C.2 Noise limit value
The washing noise limit value for washing machines is. 62 dB (A weighted)
(sound power level);
The dehydrating noise limit value for washing machines is. 72 dB (A weighted)
(sound power level).
C.3 Test code
C.3.1 Test conditions
C.3.1.1 Except for the tests which specifically provide for the test environmental
conditions, the type test shall be conducted in a room with an ambient
temperature of (20±5)°C and a relative humidity of 60%~70% but without
outside air flow, strong sunlight, and other heat radiation effects.
C.3.1.2 The test power supply is a single-phase AC sine wave. The fluctuation
range of voltage and frequency shall not exceed ±1% of the rated value.
C.3.1.3 The washing machine under test shall be tested under the use state
specified in the manufacturer’s instructions.
C.3.1.4 The inlet water temperature of the washing machine with heating
equipment is (15±2)°C.
C.3.1.5 The inlet water temperature of tumbling-box washing machine without
heating equipment is (50±2)°C.
C.3.1.6 The inlet water temperature of impeller-type/agitator-type washing
machine without heating equipment is (30±2)°C.
C.3.1.7 The water inlet pressure of full-automatic washing machine is

Appendix D
(normative)
Noise limit value for microwave ovens
D.1 Scope
This Standard applies to microwave ovens with a nominal microwave frequency
of 2450 MHz and a rated microwave output power of not more than 1 kW
(including 1 kW), also applies to microwave ovens with a grill function (including
convection grill function with hot air).
The noise value for combined, multi-functional composite, and other types of
microwave ovens is examined separately.
D.2 Noise limit value
The noise limit value for microwave ovens is. 68 dB(A) (sound power level).
D.3 Test code
D.3.1 Test environment
PROVIDE a laboratory with a free field above the reflection plane, that is, a
semi-anechoic chamber (Whether the noise test environment meets the
requirements of this Standard shall be evaluated according to 4.4 in GB/T
4214.1-2000).
D.3.2 Background noise requirement

measured during the operation of sound source AND the sound pressure level
of background noise shall be greater than 10 dB.
D.3.3 Noise test conditions
Microwave ovens or combined microwave ovens shall be placed in normal use
condition. If extraneous vibration occurs in the measurement, it shall use elastic
mounting to eliminate the effect of extraneous vibration.
Note. Elastic cushion. rubber (Shore hardness is 45) cushion with a thickness of 5 mm.
