Xenon Light Fastness Test Chamber

Name: Xenon Light Fastness Test Chamber
Brand: Xi'an LIB Environmental Simulation Industry

LIB xenon light fastness test chamber simulates solar illumination, temperature, humidity and rain on materials and products to evaluate their light resistance and aging properties of materials. The use of xenon arc lamps with 300nm ~ 400 nm(340nm or 420nm) bandwidth as light sources produces a full spectrum of light that is similar to natural sunlight, including ultraviolet, visible light and infrared light. Two types of sample holder: rotating type and flat shelf type are available.

Model: XL-S-750, XL-S-500

Standard: IEC 60068-2-5, IEC 60068-2-27,ASTM G26,ISO 105, ISO 4892-2, ASTM G155, ASTM G151, ASTM G155,ISO 105-B02 (EN) (DIN), ISO 105-B04 (EN) (DIN).

Xenon Light Fastness Test Chamber Features and Benefits

1. Xenon lamps emit a continuous spectrum from ultraviolet to visible light to infrared, and the spectral distribution of natural sunlight is highly similar. High-power water-cooled, air-cooled xenon arc lamps run smoothly for more than 1600 hours.

2. Precise control of the temperature ranging from ambient to 100℃in the xenon light fastness test chamber and humidity is adjustable from 50%RH to 98%RH. Water spray system can simulate rain weather to check water resistance and color stability.

3. A wide selection of filters such as Daylight Q, Daylight B/B, Window Q, Window B/B filters. These filters only allow specific wavelengths of light to shine on the sample in order to more accurately study the effects of different wavelengths of light on the material.

4. Diverse sample holder design, flat shelf type, rotating drum type, which can be selected according to the shape, size and test requirements of the sample.

Configuration of Xenon Light Fastness Test Chamber

①Workroom	Both the workroom interior and multi-layer perforated shelf sample holder are SUS304, The Xenon lamp is located at the top of the workroom.4500W/6500W optional. Option 1: Water cooled xenon lamp By circulating water around the lamp to take away the heat generated, the temperature distribution of the lamp is more uniform, so that the output of light is more uniform and stable. Option 2: Air-cooled xenon lamp The use of air flow, through a fan to blow cold air over the lamp surface.
②Spray system	Water is piped to the sprinkler head, where it is sprayed out under pressure to simulate rain or spray conditions. Spray time, frequency, water and other parameters can be set and adjusted.
③ Air circulation system	Adopt high and low temperature, low noise air conditioning fan. Air circulates in the test chamber. Avoid high or low local temperature and uneven humidity.
④ Heating system	Ni-cr alloy electric heating element is adopted. Fast heating speed and high thermal efficiency.
⑤Humidity system	The humidifier increases the humidity in the air through the evaporation of water, and the humidification is uniform and stable.
⑥ Control system	The control system can accurately control and adjust the parameters of light intensity, temperature, humidity, spray time, etc., and can be programmed according to the test requirements to realize automatic cyclic testing.
⑦ Refrigeration system	Using the principle of compressor refrigeration, through the circulation of refrigerant, the heat in the test box is taken away. Including compressor, condenser, evaporator, throttling device.
