ISO 4892 UV Weatherproof Accelerated Aging Environmental Test Chamber
Brief Introduction:
UV weathering test chamber is designed and manufactured in accordance with ISO 4892-82, ASTM G 154, ISO 4892-3 standards; ISO 11507; ASTMD 4329, etc., can simulate the damage caused by sunlight, rain and dew. Fluorescent UV lamp was used to simulate the effect of sunlight, and condensed water was used to simulate rain and dew. The material under test was placed under a certain temperature and the cyclic program was used to carry out the alternating test of light and water. Testing rooms can take days or months, which can reproduce the dangers that occur outdoors. The types of hazards include: fading, discoloration, loss of luster, pulverization, cracking, turbidity, bubbles, embrittlement, strength loss and oxidation. Uv test data helps select new materials and evaluate how formula changes affect the durability of new products. Widely used in coating, ink, paint, resin, plastic, rubber, printing and packaging, aluminum profiles, adhesives, automobiles, motorcycles, cosmetics, metal, electronics, electroplating, medicine and other industries.

Equipment structure
| Parallelly install 8 lamps in a stainless steel chamber to stimulate the ultraviolet light. The temperature of the inner chamber is raised by the humidification system to simulate the humid environment, and then the spray system is used to simulate the rain. According to the programmed setting to make the three different environments cycle alternately. |
| Sample installation method | The test sample is fixed on the test stand and face the fluorescent lamp |
| Test temperature | Three different temperatures of 50, 60, and 70 °C, which can be used for illumination, and 60 °C is preferred; the temperature in the condensation stage is 50 °C, and the temperature tolerance uniformity is ±3 |
| Lighting cycles of each condensation | The cycle of each condensation of illumination can be selected from two cycles: One is 4H illumination and 4H condensation; and the other is 8H illumination and 4H condensation. After the first illumination of 400-450H, each row of lamps needs to be replaced with a fluorescent lamp, and the other lamps shall compensate for the loss caused by the aging of the lamps according to the lamp cycle and replacement method. This operating mode ensures that the lifespan of each lamp is 1600-1800H. |
| Precautions when replacing the lamp | When replacing the lamp, the water tray should be wiped dry and cleaned to avoid the formation of scale |
