Except for the following contents, this Chapter of GB/T 4214.1-2017 is applicable. 1.1 Scope
1.1.1 Overview
Added:
This document applies to household and similar single-unit electric dishwashers, with or without automatic program controls, using hot and / or cold water sources, which may be separated or permanently connected to a water supply or drainage system, intended to be placed against a wall on the floor, embedded or placed under a counter, under a kitchen operating surface or under a sink, and mounted on a wall or on a counter.
1.1.2 Type of noise
Replaced:
The methods specified in GB/T 6881.2-2017, GB/T 6881.3-2002 and GB/T 3767-2016 can be used to test the noise emitted by dishwashers.
1.1.3 Size of sound sources
Replaced:
The method specified in GB/T 3767-2016 is applicable to sound sources of any size. When adopting GB/T 6881.2-2017 and GB/T 6881.3-2002, it should be noted that the maximum size of the dishwasher under test shall satisfy the requirements specified in GB/T 6881.2-2017 and GB/T 6881.3-2002.
1.2 Determined Quantity
Added:
The requirements for the declared values of noise are beyond the scope of this document. NOTE 101: for the determination and verification of the noise emission values declared in the product specification, see GB/T 4214.10-2021.
Reverberant Fields - Comparison Method for a Hard-walled Test Room (ISO 3743-1:2010, IDT) Added:

3 Terms and Definitions
The following terms and definitions are applicable to this documents.
This chapter of GB/T 4214.1-2017 is applicable, except for the following contents. 3.3 operational cycle
Added:
The dishwasher’s operational cycle starts when the program starts (excluding any user-set delays) and ends when all activity ceases (i.e., the end of the cycle); at the end of the cycle, all activity in the dishwasher has stopped. In other words, the dishwasher may revert to a power- off mode, or the dishwasher may have a steady state of power consumption before being turned on or off by the user.
NOTE: the program termination prompt tone should be turned off or minimized. If this operation cannot be performed, then, the prompt tone shall be included in the measurement. 3.101 rated dishwasher capacity
When loaded in accordance with the manufacturer’s instructions, the total number of sets of tableware (place setting and service pieces) that can be washed and dried in one cycle. NOTE: the manufacturer declares the rated dishwasher capacity of the dishwasher and expressly indicates the number of sets of tableware.
[source: IEC 60436:2015, 3.1.12]
3.102 place setting and service pieces
The tableware defined in IEC 60436:2015, or the tableware defined in GB 38383-2019. NOTE: the tableware used is stated in the test report.
3.103 drying
The operating stage, during which, the load is dried. Drying starts when the washer pump stops working after the final rinse and ends at the end of the operational cycle. 4 Measurement Method and Acoustic Environment
This chapter of GB/T 4214.1-2017 is applicable, except for the following contents. 4.2 Direct Method
Added:
If pure tone components are present in the noise emitted by the sound source, then, the estimated value of the standard deviation of sound pressure levels measured in an exclusive reverberation chamber may increase. Under this circumstance, in accordance with the stipulations of GB/T 6881.3-2002, it may be necessary to add additional microphone locations or sound source locations.
4.3 Comparison Method
Added:
If pure tone components are present in the noise emitted by the sound source, then, the estimated value of the standard deviation of sound pressure levels measured in a hard-walled test room or an exclusive reverberation chamber may increase. Under this circumstance, in accordance with the stipulations of GB/T 6881.2-2017 or GB/T 6881.3-2002, it may be necessary to add additional microphone locations or sound source locations.
5 Measurement Device
This chapter of GB/T 4214.1-2017 is applicable.
6 Operation and Positioning of the Device under Test
This chapter of GB/T 4214.1-2017 is applicable, except for the following contents. 6.1 Assembly and Pretreatment of Appliances
6.1.3
Replaced:
Before starting the measurement, the inner surface of the appliance and the filter shall be clean. The salt container, if available, shall be filled with salt and water in accordance with the manufacturer’s instructions, and the rinse aid box shall be filled with rinse aid. The amount of salt and acid rinse (Type III) used shall comply with the contents of 5.8 and 5.9 in IEC 60436:2015. Then, the equipment shall be operated for at least 2 cycles in accordance with the Dishwashers shall be operated in accordance with the standard test procedures in 6.101 and loaded with the standard load specified in 6.102. In accordance with different nominal numbers of sets of place setting (and artificial pollutants), the recommended detergent dosage is also different: 5 g for 1 ~ 3 sets, 10 g for 4 ~ 7 sets, 15 g for 8 ~ 10 sets and 20 g for above 10 sets. Detergent D specified in IEC 60436:2015 shall be used.
Immediately before the start of the program, the detergent shall be placed in the location of the dishwasher specified by the manufacturer. If a dispenser is installed, the detergent shall be added in whole or in part in accordance with the manufacturer’s instructions. Before adding the detergent, the dispenser shall maintain dry and clean. Unless otherwise specified by the manufacturer, the detergent shall be put into the main compartment of the dispenser. At the beginning of the standard test procedures, the standard test load shall be dry and at room temperature. Within 2 min before the start of the standard test procedures, the glasses with artificial pollutants shall be removed from the refrigerator and placed in the dishwasher. Place in accordance with the loading scheme provided by the manufacturer. If there is no loading scheme or the loading scheme does not describe how the glasses are to be placed, then, place the glasses with frozen milk in the upper basket in a position where they can be directly spray-washed by the water from the nozzles. If the machine does not have an upper basket or the glasses cannot fit in the upper basket, then, place the glasses in the lower basket where they can be directly spray-washed by the water from the nozzles.
Care shall be taken to avoid the collision sound of the tableware due to the impact of water flow or the collision of the spray arms.
NOTE 101: under normal circumstances, the dishwasher door is opened for 3 h after an operational cycle, so as to allow the appliance to thoroughly cool.
6.5 Positioning and Installation of Appliances
6.5.2
Not applicable.
6.5.5
Added:
Appliances with non-detachable worktops and appliances specified by the manufacturer to be used only on a stand-alone basis shall be independently placed during measurement. All other appliances shall be placed in the test enclosure described in Appendix B of GB/T 4214.1-2017; if there is a worktop, it shall be removed.
The front edge (except the door) of the dishwasher cabinet designed to be built-in shall be 20 mm ~ 25 mm behind the front edge of the test enclosure.
If there is no skirting board integrated with the appliances, and the location of the skirting board is not specified in the instructions for use, then, the skirting board shall be tightly pressed on the appliance.
6.101 Standard Test Procedures of Noise Test
The standard test procedures of noise measurement are the same as the procedures used to measure and determine the cleaning performance, drying performance, energy consumption and water consumption in accordance with IEC 60436:2015.
6.102 Standard Test Load of Noise Test
The standard test load of noise measurement includes all sets of place settings and a corresponding number of service pieces, which jointly constitute the rated washing capacity specified by the manufacturer, which is the load specified in IEC 60436:2015, or the load specified in Appendix B of GB 38383-2019. The standard test load shall be loaded in accordance with the rated washing capacity and the load placement scheme specified by the manufacturer in the instructions for use. If no load placement scheme is provided, then, the load placement shall be the same as that used to measure and determine the cleaning performance, drying performance, energy consumption and water consumption.
The standard test load consists of a glass filled with frozen artificial pollutant. Except for this glass, the rest of the load shall be clean. The artificial pollutants shall use ultra-heat treated milk, with a fat content of 3.5%  0.5%.
Depending on different nominal capacities, different amounts of artificial pollutants shall be used. 50 mL for 1 ~ 3 sets, 100 mL for 4 ~ 7 sets, 150 mL for 8 ~ 10 sets and 200 mL for above 10 sets.
