BS EN ISO 105-A05:1997

This standard BS EN ISO 105-A05:1997 Textiles. Tests for colour fastness is classified in these ICS categories:

• 59.080.01 Textiles in general

This part of ISO 105 specifies an instrumental method for assessing the change in colour of a test specimen in comparison to an identical untreated reference, and the calculations undertaken to convert the instrumental measurements into a grey scale rating.

This method is intended as an alternative to the many national methods for visual evaluation of the effect of a colour fastness test on any textile material.

NOTE 1 There may be a difference between instrumental and visual assessments of specimens due to fluorescence, and/or other factors.
