ISO 105-B06:1998 pdf download.Textiles - Tests for colour fastness
1 Scope
This part of ISO 105 specifies a method for determining the colour fastness and ageing properties of all kinds and forms of dyed and printed textiles and/or other organic substrates under the action of an artificial light source representative of natural daylight (D65), and under the simultaneous action of heat. Of the four different sets of exposure conditions specified (see 6.1), three use D65, and the fourth a somewhat lower cut-ott wavelength. The test method gives special consideration to the light and heat conditions that occur in the interior of a motor vehicle.
The four different sets of conditions specified are known to give similar but not necessarily identical results.

3 Principle
3.1 Light fastness test
A specimen to be tested is exposed to artificial light under prescribed conditions, along with a set of blue wool references. The colour fastness is assessed by comparing the change in colour of the test specimen with that of the references used, or with the grey scale in accordance with ISO 105-A02, or by means of a colour measuring instrument in accordance with ISO 105-A05 after the specimen has been exposed to a specified amount of radiant energy.
3.2 Ageing test
A specimen to be tested, together with reference 6 (see ISO 105-B02), is exposed to artificial light under prescribed conditions. The change in colour of the specimen is evaluated on the grey scale in accordance with ISO 105-A02, or by means of a colour-measuring instrument in accordance with ISO 105- A05. Additional ageing criteria, such as mechanical properties, may also be evaluated.
NOTE Attention should be paid to the principles for specifying and carrying out the tests, and for evaluating the test results according to ISO 105-A01.ISO 105-B06 pdf download.
