2 Normative references
The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
GB/T 2828 (all parts) Sampling procedures for inspection by attributes
GB/T 2829 Sampling procedures and tables for periodic inspection by attributes (apply to inspection of process stability)
GB/T 4288 Household and similar electrical washing machine 3.8 the maximum allowable value of energy consumption the maximum allowable value of energy consumption of washing machines to complete a working cycle under rated working conditions 3.9 energy efficiency grade of household electric washing machines energy efficiency grade of washing machines, determined by energy consumption per kilogram, water consumption per kilogram, and ratio of washing ability 3.10 water efficiency grade of household electric washing machines water efficiency grade of washing machines, determined by water consumption per kilogram, energy consumption per kilogram, and ratio of washing ability 3.11 allowed deviation between energy label and test data deviation between energy consumption, water consumption, actual measured value of clean ratio caused by repeatability and reproducibility of test data and labeled nominal value of energy efficiency
4 Technical requirements
4.1 Energy efficiency and water efficiency grades
4.1.1 Energy efficiency grades
Energy efficiency of washing machines is divided into 5 grades; grade 1 is the highest. Energy efficiency grades of washing machines are based on the actual measured energy consumption per kilogram, water consumption, clean ratio of washing machines. The actual measured energy consumption per kilogram, water consumption, clean ratio of each grade shall comply with provisions in
Table 1 and Table 2.
4.2 Maximum allowable values of energy efficiency and water efficiency
Energy consumption per kilogram, water consumption and clean ratio of washing machines shall comply with stipulated values of grade 5 of energy efficiency grade or grade 5 of water efficiency grade. Meanwhile, the average of three tests of rated capacity and the average of three tests of partial capacity shall comply with the minimum limit requirements of clean ratio, dehydration rate, rinsing performance in GB/T 4288; otherwise the product shall be concluded as unqualified.
4.3 Evaluation values of energy conservation and water conservation
Evaluation values of energy conservation and water conservation of electric washing machines are grade 2 of Table 1 ~ Table 4.
5 Test methods
5.1 Test conditions and test equipment
Perform in accordance with relevant provisions in GB/T 4288.
5.2
Tests for energy consumption, water consumption, clean ratio, dehydration rate and rinsing performance
Based on group-batch principles of GB/T 2828, GB/T 2829, extract three samples to simultaneously test the energy consumption, water consumption, clean ratio, dehydration rate and rinsing performance. Take the average value as the actual measured energy consumption, water consumption and clean ratio of this type of product; convert into energy consumption per kilogram and water consumption per kilogram.
5.2.1
Tests for rated capability and partial capability of test washing machines shall be conducted in accordance with standard working cycle stipulated in the instructions for use. Partial capability test shall choose same program with rated capability test. If the manufacturer otherwise noted, only water level can be adjusted according to manufacturer's instructions.
5.2.2 Perform in accordance with relevant test methods stipulated in GB/T
4288.
5.2.3 Respectively conduct the test under rated capability and partial
