introduction
The test conditions specified in this section provide sufficient accuracy for determining the noise emitted by the appliance and comparing the results of different laboratory tests.
Sex, while simulating the actual use of the dishwasher as much as possible.
To avoid instability caused by foam, the test was carried out using a clean load and without detergent or rinse.
It is recommended to consider the noise level as part of a comprehensive test procedure that includes multiple aspects of the dishwasher's characteristics and performance.
This section considers the noise of water, drainage, pre-washing and intermediate rinsing. Therefore, the operating conditions must be noted during these operations.
This test method only deals with airborne noise.
