COLOUR FASTNESS RESISTANCE TO ARTIFICIAL LIGHT EXPOSURE

ITEM 33A

The equipment is composed of reflecting units which embody special metallic vapours halogenous lamps to perform accelerated aging tests with artificial light.
These lamps are capable of granting 4 times more light according to the same Watt value, of any other lamp on the market.
They also have a natural and brilliant reflection of color with precise characteristics of daylight (they provide 95 lumens per Watt).
The space subjected to radiation is 400 mm in diameter and the temperature display and adjustment system allows automatically activating the cooling fans inside the cell.
Complete tests such leather goods, footwear, plastic materials, textile, etc. can be tested.

INTERNATIONAL STANDARDS:
– IUF 402 Colour fastness of leather to light: Xenon lamp;
– EN ISO 105-B02 Colour fastness to artificial light: Xenon arc fading lamp test;
UNI  ISO 4582 Plastics — Determination of changes in colour and variations in properties after exposure to glass-filtered solar radiation, natural weathering or laboratory radiation sources;
– UNI ISO 4892 test conditions replicating weathering effects on plastic materials through the use of moisture and xenon arc light;
– UNI 7097;
– UNI 7095.

OPTIONAL:
Grey Scale for assessing change in colour UNI EN ISO 105 A02 –  IUF131;
Grey Scale for assessing change staining UNI EN ISO 105 A03- IUF 131;
–  Blue Scale is used to test colour fastness of cloths or leather exposed to light  UNI EN ISO  105 from B01 to B08.
