Textiles -- Tests for colour fastness -- Part E05: Colour fastness to spotting: Acid
This standard has been revised by ISO 105-E05:2010
ISO 105-E05:2006 specifies a method for determining the resistance of the colour of textiles of all kinds, and in all forms, to the action of dilute solutions of organic and mineral acids.
Four tests differing in severity are provided. Any or all may be used, depending upon the nature of the fibre.
