Overview
The double-layer UV aging test chamber uses a fluorescent UV lamp as the light source, and simulates the UV radiation and condensation in natural sunlight to conduct accelerated weather resistance tests on materials, in order to obtain the results of material weather resistance. It can simulate environmental conditions such as UV, rain, high temperature, high humidity, condensation, and darkness in natural climate. By reproducing these conditions, it can merge them into a cycle and automatically complete the cycle.

The fluorescence ultraviolet aging test chamber provides two test chambers, upper and lower. Can run independently. Each test chamber can accommodate12Sample holderThe whole machine can accommodate48A standard sample.
c)Radiation control
Optional340nmIrradiance（0.25-1.55 W/m2）Or351nmIrradiance（0.25-1.35 W/m2）Or313nmIrradiance（0.28-1.25 W/m2）Or254nmIrradiance（0.25-1.35W/m2）To meet different experimental needs.
Radiation deviation
The irradiance deviation of the fluorescence UV aging test chamber is as follows:
@340nm ±0.01W/m2
@351nm ±0.01W/m2
@313nm ±0.01W/m2
@254nm ±0.01W/m2
2.2 System Technical Description
a)light source
The climate aging test system uses fluorescenceUV lamps can simulate ultraviolet rays in sunlight very well.
Lamp type: UVA/UVB/UVCfluorescencefluorescent tube
Power: 40tile
lifespan 4000hour
Wavelength: UVA 340nmor351nm, UVB 313nm, UVC 254nm
b)Sample clamp
provide24Sample holder（75mm*300mm）Used for 48A standard specification sample（75mm*150mm）. The sample holder can also be customized according to customer requirements.
The distance from the surface of the sample to the center of the lamp tube is50mm ± 3mm
c)Condensation control
The heater heats water for condensation control, which can be automatically controlled and displayed.
Humidity during condensation:≥95% RH
d)temperature control
The temperature inside the box, blackboard thermometer temperature or black label thermometer temperature is continuously and simultaneously controlled or monitored.
Automatic air circulation system, circulating air inside the box.
Temperature range inside the box (maximum ambient temperature)35°C）：40°Cto90°C
Temperature uniformity inside the box:≤2°C
Blackboard thermometer temperature range:40°Cto110°C
Black label thermometer temperature range:40°Cto120°C
All temperature fluctuations:±1°C
e)Sample spraying
The nozzle inside the box can evenly spray deionized water onto the sample.
The sample nozzle sprays water towards the front of the sample to simulate rain, causing temperature shock and erosion effects.
f)control system
The control system of the fluorescence ultraviolet aging test chamber is based on SiemensPLC.
system includesPLC program and touch control color display screen.
g)Software features
Set and closed-loop control the following parameters:
- irradiance
- Blackboard thermometer/Black label thermometer temperature
- dew
-spray
- Temperature inside the box
Display experimental parameters and progress
Monitoring and alerting of water levels and system malfunctions
14A factory preset international standard test procedure.
4User defined test procedures can be customized, such as gradually changing irradiation, box temperature, black gauge thermometer temperature, condensation, spray (sample spray and sample rack spray), etc. to achieve user-defined test procedures or cycles. All experimental programs can be stored, called, and edited.
