DIN EN ISO 105-D01:2010-10

This part of ISO 105 specifies a test method for determining the resistance of the colour of textiles of all kinds and in all forms to drycleaning using perchloroethylene solvent. This test method is neither suitable for the evaluation of the durability of textile finishes, nor is it intended for use in evaluating the resistance of colours to spot and stain removal procedures used by the drycleaner. This test method covers colour fastness to drycleaning only; commercial drycleaning practice normally involves other operations, such as water spotting, solvent spotting and steam pressing, and so on, for which other standard test methods are available if the full response to drycleaning of the textile is to be assessed. The presence of absorbed water in drycleaning solvent, or the presence of a detergent and water in a drycleaning solvent, are known to alter the colour fastness properties of some materials. This test requires the assessment of the material under test in a dry state, using solvent alone, within containers that do not contain water. Fastness to drycleaning, without further qualification in this part of ISO 105, means fastness to drycleaning in perchloroethylene. However, if required, other solvents that are used for textile cleaning can be used. A specimen of the textile in contact with a specified adjacent fabric or fabrics in a cotton fabric bag, together with non-corrodible steel discs, is agitated in perchloroethylene (see clause 1), then squeezed or centrifuged, and dried in hot air. The change in colour of the specimen and the staining of the adjacent fabric or fabrics are assessed with reference to the original specimen, either with grey scales or instrumentally. The Committee responsible for this standard is NA 062-05-11 AA "Farbechtheit von Textilien - Deutsche Echtheitskommission DEK e. V." ("Colour Fastness of Textiles - German Colour Fastness Committee") at DIN. With respect to DIN EN ISO 105-D01:1995-04, the following changes have been made: a) the title of the standard has been changed; b) the solvent perchloroethylene has been specified in clause 1; c) DIN EN ISO 105-A05 has been added to clause 2; d) clause "Reagents and materials" has been further subdivided; e) extended description of the procedure in clause 8; f) staining of the adjacent fabrics has been added; g) fastness grade for the staining with solvent has been deleted; h) Annex ZA has been deleted.
