The number denotes the maximum dye quantity in grams which is dissolved in the given conditions in one litre of distilled water.
     
Fastness standards
Light Xenotest ISO 105-B02-1994  
Washing ISO 105-C04-1989  
Domestic and commercial laundering ISO 105-C06-1994 test E2S
Perspiration ISO 105-E04-1994

The fastness data given in tables denote:
for light fastness for other fastness data 
1 - very poor 1 - poor
2 - poor 2 - moderate
3 - moderate 3 - good
4 - fairly good 4 - very good
5 - good 5 - excellent
6 - very good
7 - excellent
8 - unsurpassed
     
The numbers at the individual dye fastness data mean:
First number - change of shade
Second number - staining of the undyed adjacent fabric made of the same material as the tested SAMPLE
Third number - staining of the undyed woolen adjacet fabric
     
For the fastness to washing at 95°C and fastness to peroxide bleaching the figures have the following meaning:
For dyeing of cotton
First number - change of shade
Second number - staining of the undyed adjacent cotton fabric
Third number - staining on the undyed adjacent viscose fabric
     
u vybarvení na viskóze
First number - change of shade
Second number - staining on the undyed adjacent viscose fabric
Third number - staining of the undyed adjacent cotton fabric
     
For fastness in mercerizing asterixat the figure means effect to deeper shade
     
Saturation and exhaustion curves
Saturation curves express the dyeing saturation in dependence on the increasing dye concentration in the dyebath. From them it is possible to determine the saturation point of the dyestuff, i.e. the maximum effective dye concentration. On the X axis there are assigned the integrated reflectance I values
 
ostazin_s_zm01
 
Where K/S is the Kubelka-Munk equation
ostazin_s_zm02
 
β jis surface reflectance
ostazin_s_zm04
are the colour matching response functions for the D65 light and 10°standard observer
 
Exhaustion curves were designated from initial concentration of 1/1 standard depth by standard exhaustion method and show the amount of the dye exhausted from the dyebath in dependenc on the dyeing time.
