Scope and field of application
1.1 This part of IS0 105 specifies methods intended for determining the resistance of the colour of textiles of all kinds and in all forms to domestic or commercial laundering procedures used for normal household articles. Industrial and hospital articles may be subjected to special laundering procedures which may be more severe in some respects.
1.2 The colour loss and staining resulting from desorption and/or abrasive action in one "S'' (single) test closely approximates to one commercial or domestic laundering. The results of one "M" (multiple) test may in some cases be approximated by the results of up to five domestic or commercial launderings at temperatures not exceeding 70 oC. The "M" tests are more severe than the "S" tests because of an increase in mechanical action.
1.3 These methods do not reflect the effect of optical brighteners present in commercial washing products.
Principle
A specimen of the textile in contact with specified adjacent fabric or fabrics is laundered, rinsed and dried. Specimens are laundered under appropriate conditions of temperature, alkalinity, bleaching and abrasive action such that the result is obtained in a conveniently short time. The abrasive action is accomplished by the use of a low liquor ratio and an appropriate number of steel balls. The change in colour of the specimen and the staining of the adjacent fabric or fabrics are assessed with the grey scales.
