Inspection standards:

The staining determination of white cotton cloth for friction shall be carried out in accordance with the provisions of Article 9 (Determination of Color Fastness) of JIS L 0801.

According to the test results, the following judgments are made

Excellent: The wet cloth test leaves no color on the white fine cloth.

B Shangjia: There is color retention on the white fine cloth during the wet cloth test, but no color retention on the white fine cloth after the dry cloth test.

C Defect: After the dry cloth test, the white fine cloth retains color.

Test steps:

1. Plug in the power supply (AC220V, 3A);

2. Turn on the power switch

3. Set the required number of experiments on the counter
