Scope

This document specifies a method for determining the consumer relevant shade change of textiles, of all kinds, (excluding silk and wool) and in all forms, to domestic/commercial laundering procedures in which a bleach activator (oxygen bleaching system) is used. The colour fastness resulting from oxygen bleaching in this test provides an indication of the shade change behaviour observed after multiple domestic/commercial launderings.

This document is not applicable for the assessment of the dye staining of adjacent fabrics, where suitable methods are described in ISO 105-A04.

This document specifies a procedure incorporating the use of ECE[1] non-phosphate reference detergent, sodium perborate tetrahydrate or sodium percarbonate, and the bleach activator tetra-acetylethylenediamine (TAED) (see Annex A) and a procedure incorporating the use of AATCC 1993 zero phosphate reference detergent (without optical brightener), sodium perborate monohydrate or sodium percarbonate and the bleach activator sodium nonanoyloxybenzene sulfonate (SNOBS) (see Annex B).

This method has been designed for the detergents and bleach systems given. Other detergents and bleach systems may require different conditions and levels of ingredient.
