This document applies to single unit electric dishwashers for household and similar use, with or without automatic programme control, for cold and/or warm water supply, for detachable or permanent connection to water supply or sewage systems, intended for placing on the floor against a wall, for building-in or placing under a counter, a kitchen worktop or under a sink, for wall-mounting or on a counter.
1.1.2 Types of noise
Replacement:
The methods specified in GB/ T 6881.2-2017, GB/ T 6881.3-2002 and GB/ T 3767-2016 can be used for measuring noise emitted by electric dishwashers.

1.2 Object
Addition:
Requirements for the declaration of noise emission values are not within the scope of this document.
Note 101: For determining and verifying noise emission values declared in product specifications, see GB/T 4214.10-2021.
1.3 Measurement uncertainty

This clause of GB/T 4214.1-2017 is applicable except as follows.
Replacement:

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
This clause of GB/T 4214.1-2017 is applicable except as follows.
3.3
operational cycle
Addition:
starts with the initiation of the programme (excluding any user programmed delay) 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 ceased, i.e. the dishwasher may revert to off mode or it may have a steady state power consumption until the user opens the dishwasher or turns the unit off.
Note: Audible program end signals should be switched off or set to the lowest configuration. If this is not possible, the audible signals shall be included in the measurement.
3.101
rated dishwasher capacity
whole number of place settings together with the serving pieces which can be cleaned and dried in one cycle when loaded in accordance with the manufacturer’s instructions
Note: The rated dishwasher capacity is declared by the manufacturer and expressed as a number of place settings.
[Source: IEC 60436 :2015, 3.1.12]
3.102
place setting and service pieces
tableware and pieces as defined in the dishwasher performance standard IEC 60436:2015 or GB 38383-2019
Note: The tableware used is specified in the test report.
3.103
drying
operational period during which the load is dried. Drying begins when the washing pump has stopped after final rinse and ends with the end of the operational cycle.
4 Measurement methods and acoustic environment
This clause of GB/T 4214.1-2017 is applicable except as follows.
4.2 Direct method
Addition:
If pure tone components are present in the noise emitted by the source, the estimated standard deviation of the measured sound pressure levels in the special reverberation room can increase. In such cases, additional microphone positions or source positions can be necessary, as specified in GB/T 6881.3-2002.
