(normative)
Antibacterial Function Test Methods for Electric Washing Machines with
Antibacterial Function
By comparing the residual viable bacteria count under the common (standard) washing
program when the antibacterial function is not activated and activated, determine the
eliminating bacterial rate of the electric washing machine with antibacterial function.
Among them, the group that has not activated the antibacterial function is the control
group; the group that has activated the antibacterial function is the test group.

AA.1.1 Standard washings (abbreviated as load cloth)
The bleached medium plain cloth required in GB/T 411: the warp yarns are 21 ± 2
counts; the weft yarns are 21 ± 2 counts; made into a 330 mm 330 mm square towel
through desizing pre-treatment.
AA.1.2 The test load is 30% of the rated load.
AA.2 Sample Piece
Use the bleached medium plain cloth that complies with the requirements of GB/T 411;
the warp yarns are 21 ± 2 counts; the weft yarns are 21 ± 2 counts; through desizing
pre-treatment, make it into a 100 mm 100 mm square towel.
AA.3 Bacteria
AA.3.1 The bacteria are Staphylococcus aureus and Escherichia coli.
AA.3.2 A diluent with a bacterial concentration of 1.0 109 CFU/mL ~ 9.0 109 CFU/mL.
AA.4 Test Procedures
AA.4.1 Control group: adopt the common (standard) washing program.
AA.4.2 Test group: adopt the common (standard) washing program + antibacterial
function or antibacterial program.
