UV irradiation chamber BS-02

The irradiation chamber BS-02CT is a chamber to test samples according IEC 60335-1:
“Household and similar electrical appliances – Safety – Part 1: General requirements - Edition 5.2”
This test is designed for non-metallic materials that are exposed to direct or reflected UVC radiation from 200 nm to 280 nm. The test can be used to test radiation stability against UVC radiation that can cause aging like discolorations, changes in material properties, crack formation and smell.
Therefore the UVC low pressure mercury lamps emit a continuous spectral irradiance of 10 W/m² at 254 nm.
IR heater heat up the samples so that a black-panel temperature of 63 °C ± 3 °C can be reached and controlled.
The time can be set to an exposure duration of 1000 h.
The irradiation chamber BS-02CT can also be used to test material properties that are disinfected by UV-C. Typically the UVC dose of a daily disinfection for a period of two years can be accelerated to 12 hours.
The BS-02CT is compact, robust equipment for the time- or dose-controlled irradiation of samples with UVC.
The interior irradiation chamber has a base area of 46 x 32 cm and a height of 20 cm. The sample chamber operating temperature is about 25°C to 70 °C so that thermal damage to the specimen can be avoided or accelerated.
Due to the high uniformity of the irradiation, the samples may be positioned in any order.
The irradiation control UV-MAT can control the UVC lamps to achieve a constant dose independent of lamp aging, contamination or temperature. The dose is measured with a calibrated sensor. For this purpose, the sensor already contains an extremely precise analog-digital converter and a temperature sensor. This can also be calibrated according to ISO/IEC 17025 on request.
The UV-MAT can optionally be controlled by a PC. This allows multi-stage irradiation and documentation of the irradiation.
Temperature controlling is made by an extern PID controller with measures the temperature of a thermocouple or black-panel temperature sensor.
