1.1 This standard prescribes a method for determination of colour fastness of textile materials of all kinds and in all forms to dry-cleaning.
1.2 The test prescribed in this standard is not suitable for evaluation of the durability of textile finishes, nor it is intended for use in evaluating the resistance of colours to spot and stains removal procedures used by the dry-cleaners ( see Notes 1 and 2 ).
Note 1 — This test covers colour fastness to drycleaning only; commercial dry-cleaning practice normally involves other operations, such as water spotting, solvent spotting, steam pressing, etc, for which other standard test methods are available, if the full 'drycleanability' of the textile is to be assessed.
Note 2 — The presence of absorbed water in either the fabric or dry-cleaning solution, or the presence of a detergent water in the dry-cleaning solution, has not been found to be a critical factor in assessing colour fastness. This test gives results which correlate satisfactorily with those obtained in commercial drycleaning.
