规定了洗涤后试样以下特性的测定方法:固有灰化、固有黄变、有机沉积物含量增加、焚烧残渣增加、断裂强度总体降低，由于洗涤和洗涤过程中的机械因素导致纤维素的化学降解而导致断裂强度降低。附件包括白度增加（或减少）和化学磨损的测定，以及灰阶和反射测量。

Methods for the determination of the following characteristics of the test pieces after washing are specified: intrinsic greying, intrinsic yellowing, increase in organic deposit content, increase in incineration residue, overall decrease in breaking strength, decrease in breaking strength resulting from chemical degradation of cellulose due to laundering and from mechanical factors in laundering. Annexes contain the determination of increase (or decrease) in degree of whiteness and of chemical wear and further a grey scale and the measurement of reflection.
