Ultraviolet aging test box
Ultraviolet aging test chamber is suitable for performance reliability test of various industrial products. Refer to GB/T14522-93 National Standards of the People's Republic of China - Plastics, Coatings, and Rubber Materials for Mechanical Industry - Accelerated Test Method for Artificial Weather" GB/T16585 -1996 "People's Republic of China National Standard - Vulcanized Rubber Artificial Weathering (Fluorescent UV Lamp) Test Method" and GB/T16422.3-1997 "Plastic Laboratory Light Source Exposure Test Method" and other corresponding standard terms design and manufacture;
The UV aging test chamber meets all the current UV aging test standards such as ASTM D4329, D499, D4587, D5208, G154, G53, ISO4892-3, ISO11507, EN534, prEN1062-4, BS2782, JISD0205, and SAEJ2020.
UV aging test chamber with light source
For some applications, water spray can better simulate the end-use environmental conditions. Water showers are extremely useful in simulating the mechanical erosion due to temperature changes and due to rain flushing. Roofing, automotive materials, and coatings used on metal constructions or structures often experience abrupt temperature changes. For example, during the hot summer months, when heat accumulates, it suddenly dissipates due to heavy rain. The consequences of this drastic temperature change are a challenge for many materials. UV accelerated weathering tester/spray type is specifically designed to reproduce this condition.
Due to frequent erosion from rain, the paint layer of wood, including paint and colorants, will appear to be corroded. Recent studies have shown that this rain erosion action can wash away the paint layer with anti-degradation effect on the surface of the material, thereby directly exposing the material itself to the destructive influence of UV and moisture. This process can be repeated many times, resulting in a material degradation phenomenon that cannot be reproduced by condensation alone.
Reference standard
The light source uses 8 imported ultraviolet fluorescent lamps with a rated power of 40W as the light source. Ultraviolet fluorescent tubes, distributed on both sides of the machine, 4 on each side. UVA-340 and UVB-313 light source for users to choose configuration;
The wavelength range of UV-A is 315-400nm, and the luminous spectral energy of the lamp is mainly concentrated at the wavelength of 340nm.
The wavelength range of UV-B is 280-315nm, and the luminous spectral energy of the lamp is mainly concentrated at the wavelength of 313nm.
Ultraviolet aging test chamber will decay gradually with time due to ultraviolet light energy output. In order to reduce the test impact due to light energy attenuation, this test box is used for every 1/4 of fluorescent lamp life in eight lamps (lamps The lifetime is: 1600H). An old lamp is replaced by a new lamp. The position of the lamp is changed as shown in the figure below. Thus, the UV light source always consists of a new lamp and an old lamp, so that a constant light energy is output.
