What is the concept of washing capacity of 7.5 kg washing machine?

The washing capacity of the washing machine of 7.5 kg means that the washing machine can wash 7.5 kg of dry clothes at most, which is the maximum capacity of the washing machine. The washing capacity is the rated washing capacity of the washing machine, which is determined according to the national standard GB/T 4288-2008 Electric Washing Machines for Household and Similar Uses. According to the standard, the rated capacity refers to the weight of pure cotton cloth that can be washed and dried (the moisture content is lower than 8%), and the unit is kilograms (kg). The standard simulated load includes sheets, shirts, pillow towels and handkerchiefs, which are placed in a specified proportion. Under the rated load, the washing ratio of the washing machine using the standard washing procedure should be not less than 0.70. The standard stipulates that the washing water temperature of the standard procedure is 30 degrees Celsius for the pulsator washing machine and 60 degrees Celsius for the drum washing machine.
