Scope 1.1 This part of ISO 105 specifies a method for determining the resistance of the colour of textiles of all kinds and in all forms to the action of steam-pleating processes. The materials are not pleated during the test, and it is emphasized that the test is not intended for assessing the quality of the pleating process. 1.2 Three tests differing in severity are provided; one or more of them may be used depending on the requirements.
