ISO 105 X12-2016 pdf free.Textiles一Tests for colour fastness – Part X12: Colour fastness to rubbing.
This part of Iso 105 specIfies a method for determining the resistance of the colour of textiles of all kinds, including textile floor coverings and other pile fabrics, to rubbing off and staining other materials.
The method is applicable to textiles made from all kinds of fibres in the form of yarn or fabric, including textile floor coverings, whether dyed or printed.
Two tests may be made, one with a dry rubbing cloth and one with a wet rubbing cloth.

3 Principle
Specimens of the textile are rubbed with a dry rubbing cloth and with a wet rubbing cloth. The machine provides two combinations of testing conditions through two alternative sizes of rubbing finger: one for pile fabrics and one for solid colour or large print fabrics.
4 Apparatus
4.1 Suitable testing device for determining the colour fastness to rubbing, using a reciprocating straight line rubbing motion and two alternative sizes of rubbing fingers.
4.1.1 For pile fabrics, including textile floor coverings: rubbing finger with a rectangular rubbing surface with the lead edge rounded measuring 19 mm x 25,4 mm (crock block).
The rubbing finger shall exert a downward force of (9 ± 0,2) N, moving to and fro in a straight line along a (104 ± 3) mm track.
NOTE 1 Difficulty might be experienced In making assessments of the degree of staining on the rubbing cloth when pile fabrics are tested using the (16 ± 0,1) mm diameter rubbing finger due to heavier staining occurring on the circumference of the stained area, i.e. haloing. The rubbing finger described in 4.1.1 will eliminate the haloing with many types of pile fabrics.ISO 105 X12 pdf free download.
