Weather color fastness tester simulate the real-life environmental conditions and accelerate the aging process of the materials being tested. The color fastness test measures the ability of the material to resist fading or changing color when exposed to light. During the test, the fabric sample is exposed to high-intensity light from a xenon arc lamp. This light simulates natural sunlight and includes UV radiation that causes the fabric to break down and lose its color. The sample is also subjected to controlled temperature and humidity, which further accelerates the aging process.

Features

Full Spectrum Xenon Lamps

Xenon arc lamps give the best reproduction of full spectrum natural sunlight. LIB xenon lamps are air-cooled or water-cooled, which makes them more economical, highly efficient and very low maintenance. Standard lamps last for 1600 hours and the xl-750 uses one lamp per machine. Enhanced lamps last for 1600 hours at normal irradiance and 1000 hours at high irradiance.

Temperature Monitoring & Control

Control of temperature is important because it influences the rate of degradation. Specimen exposure temperature is precisely controlled in the LIB xl-750 tester using black panel and chamber air temperature sensors. The black panel temperature can be set at any point between 35ºC and 85ºC, depending upon whether the black panel is insulated or uninsulated, irradiance level, filter type, lamp age, chamber air temperature and ambient room temperature.

Humidity Control

Relative humidity (RH) control is standard in the LIB xl-750 tester. It allows the user to simultaneously control and display RH, black panel temperature, and chamber air temperature. Note that purified water is required for proper operation of the RH system in the LIB xl-750.

Optional Water Spray

Outdoor moisture attack is simulated via an optional pure water spray in the Sunshine xenon Weatherometer A spray nozzle located in the top of the chamber can be programmed to operate during either the dark or light cycle. Note that purified water is required for proper operation of the water spray and RH features in the LIB xl-750.
