1. نطاق التطبيق
ايزو 105 B02 is applicable to the determination of the colour fastness of all types and forms of textiles to artificial light sources (simulated natural daylight D65). This standard also applies to white textiles (bleached or fluorescent white).

This standard allows the use of two different sets of blue wool reference materials, namely ISO: levels 1-8; AATCC:L2-L9. The test results of the two reference materials are not necessarily equivalent.

خطوة 3: مبادئ
The same set of standard blue wool was exposed to the sun (artificial light) under the specified conditions. Ratings were made by comparing the sample color change with the standard blue wool color change.

For white samples, ratings were obtained by comparing the whiteness change of the sample with the standard blue wool color change.

4. Standard materials and equipment
4.1 Reference Material

Two sets of reference materials namely ISO: 1-8; AATCC: Both L2-L9 can be adopted, and the results are not comparable.

4.1.1 المواد المرجعية 1-8

1: Very low colour fastness

ايزو 105 ب02-2014 – اختبار ثبات ألوان المنسوجات للضوء الاصطناعي – تبييض مصباح قوس زينون

8: Very high fastness

High grade standard wool is about twice as light resistant as low grade wool.

4.1.2 Reference material L2-L9

High grade standard wool is about twice as light resistant as low grade wool.

4.1.3 Humidity control substance

Effective humidity: air and surface temperature and air relative humidity (which controls the surface of the sample during light exposure)

محتوى الرطوبة), which can be measured by measuring specified humidity control substances.

For the purpose of testing in this part of ISO 105, the humidity control substance is designated as red azo-dyed cotton cloth.

Control substances have been tested and calibrated south facing at various locations in Western Europe at different times of the year. Blue standard wool has been tested together in sealed tanks (0 ل 100% air humidity); The results do not change much, with the averages as follows:
When the samples were tested under the conditions set in the temperate zone ISO 105 B01, the average color fastness of the control substances was 5.

4.2 معدات

4.2.1 Xenon arc lamp is air-cooled or water-cooled

Intensity change: AVG.+10%

Recommended levels of luminescence:

تبريد الهواء: 42W/m2x Wavelength, wavelength of 300-400nm

Water cooling: 1.1W/ m2x Wavelength, wavelength is 420nm

The sample and specimen should be at the same distance from the lamp.

أ) مصدر ضوء: in a well-ventilated exposure box. Xenon arc light source temperature 5500K~6500K

ب) Optical filter: located between the light source, the sample and the standard wool, so that the ultraviolet light is stabilized and weakened.

Through the light: > 90% 380nm ~ 750nm →0 310nm~320nm

ج) Heat filter: located between the light source, the sample and the standard wool, so that the infrared light is stabilized and weakened.
