NATIONALFOREWORD
This Indian Standard (Part C09) which is identical with ISO 105-C09 : 2001 Textiles - Tests for
colour fastness - Part C09: Colour fastness to domestic and commercial laundering - Oxidative
bleachresponse using a non-phosphate reference detergent incorporating a low temperature bleach
activator' issued by the International Organization for Standardization (ISO) was adopted by the
Bureau of Indian Standards on the recommendation of the Chemical Methods of Test Sectional
Committeeandapproval of theTextile Division Council.
Colourfastness of dyed/printed textile materials to various agencies during their further treatment or
actual use is an important performance requirement from the viewpoint of the user or consumer.The
variousagencies to which textile materials may be subsequently subjected may include water,acids,
alkalis, organic solvents, washing, laundering, drycleaning, perspiration, light, gaseous fumes,
bleaching,rubbing,carbonizing,felting,etc and the colour of textile materials should be fast to these
agencies and should not change considerably. The colour should also not bleed and stain the
adjacent fabrics which are subjected to these agencies along with coloured fabrics. The colour
fastness property of coloured textiles is,therefore, measured in terms of colour fastness ratings with
respecttochange incolour and/or staining of adjacent fabrics.
Since colour fastness is one of the most important requirement for export of textiles, it is considered
essential that Indian Standards related to colour fastness are completely harmonized with
InternationalStandards. The various Indian Standards on colourfastness testing,are,therefore, being
revised to align them with the corresponding International Standards and are being published in
PartsA toZ.
The test method specified in this part are intended to reflect the effect of multicycle laundering using
an activated bleach detergent by domestic or commercial laundering procedures. The washes are
carried out in a similar manner to the ISO 105-C06 tests using an activated oxygen bleach and
referencedetergent at60'C. .
St~ndard
The textof ISO has been approved as suitable for publication as an Indian Standard without
deviations. Certain conventions are, however, not identical to those used in Indian Standards.
Attentionisparticularly drawn to thefollowinq;
a) Wherever the words 'InternationalStandard' appear referring to this standard,they should
bereadas'IndianStandard'.
b) Comma (,) has been used as a decimal marker in the International Standards, while in
IndianStandards,the current practice isto use a point (.) as the decimal marker.
In this adopted standard, reference appears to certain International Standards for which Indian
Standa~ds
also exist. .The corresponding Indian Standards, which are to be substituted in their
respectiveplaces,are listed below along with theirdegreeof equivalence for the editions indicated:

This part of ISO 105 is not applicable for the assessment of the dye staining of adjacent fabrics, where suitable
methodsaredescribed inISO 105-A04.
This part of ISO 105 does not reflectthe contribution of optical brighteners,which are presentin some commercial
washing products,to shade change.
This part of ISO 105 specifies a procedure incorporating the use of ECE1) non-phosphate reference detergent,
sodium perborate tetrahydrate. and the bleach activator tetra-acetylethylenediamine (TAED). An attemative test
procedureusing theAATCC 1993zero phosphatereferencedetergent(withoutopticalbrightener),andincorporating
sodium perborate monohydrate and the bleach activator sodium nonanoyloxybenzene sulphonate (SNOBS) is
