3 Terms and definitions
For the purposes of this document, the terms and definitions given in GB/T 20290-2024 and the following apply.
3.1
standard washing program
process of dishwasher cleaning, rinsing and drying
Note 1: All washing activities are stopped at the end of the standard washing program.
Note 2: This procedure is expressly stated by the manufacturer and can be used directly on the panel.
3.2
energy consumption per standard washing program
amount of electricity consumed by a dishwasher completing one standard washing program under the test conditions specified in this document
3.3
water consumption per standard washing program
amount of water consumed by a dishwasher completing one standard washing program under the test conditions specified in this document
3.4
minimum allowable values of the energy efficiency and water efficiency for dishwashers
minimum allowable energy efficiency and water efficiency indexes for a dishwasher completing one standard washing program under the test conditions specified in this document
4 Energy efficiency grade and water efficiency grade
The energy efficiency grade and water efficiency grade of dishwasher is classified into 5 grades by the energy efficiency index and water efficiency index, with Grade 1 indicating the highest energy efficiency and water efficiency. The energy efficiency grade and water efficiency grade of the dishwasher shall be determined based on the lowest grade achieved in the two indexes specified in Table 1. The measured energy efficiency index and water efficiency index for each grade shall comply with the requirements specified in Table 1.
Table 1 Requirements for indexes of energy efficiency grade and water efficiency grade for dishwashers
5 Technical requirements
5.1 Drying index
The drying index, PD, shall not be less than 1.08.
5.2 Cleaning index
The cleaning index, PC, shall not be less than 1.12.
5.3 Noise
The noise shall comply with the requirements of GB 44498.
5.4 Minimum allowable values of the energy efficiency and water efficiency
The minimum allowable values of the energy efficiency and water efficiency for dishwashers are the energy efficiency index and water efficiency index specified for Grade 5 in Table 1.
5.5 Permissible deviation of indicated values
