1 . Test box: Fluorescent UV test box. The test box workshop is equipped with two rows of four fluorescent lamps each, a heated water tank, a sample rack, a blackboard thermometer, and a device for controlling and indicating working time and temperature

2. Fluorescent lamps: Fluorescent ultraviolet test box fluorescent lamps are divided into five types: UV-A, UV-B, UV-C, UV-D, and UV-E. Each type of fluorescent lamp exhibits different wavelengths of high peak radiation Unless otherwise specified, UV-B lamps are generally used The energy output of fluorescent lamps gradually decreases over time. In order to reduce the impact of fluorescent energy attenuation on the experiment, a new lamp tube is replaced with an old lamp tube in each row every 1/4 of the lifespan of the 8 fluorescent lamps The remaining positions are changed as shown in Figure 1, so that the fluorescent lamps are replaced regularly in sequence. In this way, the ultraviolet light source is always composed of new and old lamps, and a constant output of light energy is obtained

3 . Sample rack: The fluorescent ultraviolet test box sample rack is composed of a frame type base frame, a pad plate, and an extension spring The frame frame and pad plate are made of aluminum alloy material

4. Blackboard thermometer: The blackboard thermometer consists of a 75mm × 10mm × 2.5mm black aluminum plate connected to a temperature sensor It should be in the central range to reflect the test temperature as much as possible

5. Instruments and reference materials for measuring radiation levels: Depending on the conditions and needs, radiation level measuring instruments or reference materials can be used to determine the light energy received by the sample

A radiation meter: The radiation meter has an integrated illuminance meter and a radiation meter

B standard substance: The blue wool standard should comply with the relevant provisions of GB 730; The grey standard sample card shall comply with the relevant provisions of GB 250 Method Summary: Vulcanized rubber is subjected to aging factors such as ultraviolet light, temperature, and condensation. The changes in sample performance are tested at specified times to evaluate the weather resistance of vulcanized rubber
