This part of ISO 105 describes Test No. 4 of a series of five washing tests. A specimen of the textile, in contact with one or two specified adjacent fabrics, is mechanically agitated under defined conditions of time and temperature in a soap solution, then rinsed and dried. The change in colour of the specimen and the staining of the adjacent fabric(s) are assessed with the grey scales.
