This part of ISO 105 provides general information about the methods for testing colour fastness of textiles forthe guidance of users. The uses and limitations of the methods are pointed out, several terms are defined, anoutline of the form of the methods is given and the contents of the clauses constituting the methods arediscussed. Procedures common to a number of the methods are discussed briefly.
Colour fastness means the resistance of the colour of textiles to the different agents to which these materialsmay be exposed during manufacture and their subsequent use. The change in colour and staining of undyedadjacent fabrics are assessed as fastness ratings. Other visible changes in the textile material under test, forexample surface effects, change in gloss or shrinkage, are considered as separate properties and reported assuch.
The methods can be used not only for assessing colour fastness of textiles but also for assessing colourfastness of dyes. When a method is so used, the dye is applied to the textile in specified depths of colour bystated procedures and the material is then tested in the usual way.
For the most part, individual methods are concerned with colour fastness to a single agent, as the agents ofinterest in a particular case, and the order of application, will generally vary. It is recognized that experienceand future developments in practice can justify procedures in which two or more agents are combined.
The conditions in the tests have been chosen to correspond closely to treatments usually employed inmanufacture and to conditions of ordinary use. At the same time, they have been kept as simple andreproducible as possible. As it cannot be hoped that the tests will duplicate all the conditions under whichtextiles are processed or used, the fastness ratings are interpreted according to the particular needs of eachuser. They provide, however, a common basis for testing and reporting colour fastness.
