3. Specific Parameters

• Temperature Range and Accuracy
  • With a temperature range of -40°C to +80°C and an accuracy of ±0.3°C, the chamber can subject BMW PR303.5 trim parts to a wide spectrum of temperatures. This is crucial for testing the part's performance and durability in extreme cold and hot conditions, such as in arctic regions or desert environments. The accurate temperature control ensures that the test conditions are precisely maintained, providing reliable and repeatable results.
• Humidity Range and Accuracy
  • The humidity range of 10% to 95% RH, with an accuracy of ±2% RH, allows for a comprehensive evaluation of the effect of moisture on the trim parts. High humidity can cause swelling, warping, or corrosion, while low humidity can lead to drying and cracking. The ability to precisely control the humidity level is essential for understanding and mitigating these potential issues.
• Solar Radiation Intensity and Spectrum
  • The chamber can simulate solar radiation intensities ranging from 0 to 1200 W/m², with a spectrum closely matching that of natural sunlight. This enables the testing of the trim part's resistance to UV radiation, which can cause fading, embrittlement, and other forms of degradation. The accurate simulation of solar radiation is vital for ensuring the long-term appearance and functionality of the parts.
• Wind Speed and Precipitation Levels
  • The wind speed can be adjusted from 0 to 20 m/s, and precipitation levels can be set to simulate light rain, heavy rain, or snowfall. These parameters allow for the evaluation of the trim part's water resistance, aerodynamic performance, and ability to withstand the forces of wind and precipitation. For example, testing the part's drainage channels and seals under different precipitation levels helps ensure that no water ingress occurs during actual vehicle operation.
• Testing Volume and Payload Capacity
  • The chamber offers a customized testing volume, typically ranging from 10 m³ to 30 m³, depending on the specific requirements of BMW PR303.5 trim parts. The payload capacity is designed to handle a significant amount of parts, with a maximum capacity of up to several tons, allowing for efficient testing of multiple batches or large assemblies.
• Data Sampling Frequency and Resolution
  • The data acquisition system samples data at a frequency of up to 500 Hz, providing a highly detailed record of the environmental parameter changes. The resolution of the temperature data is 0.1°C, the humidity data is 0.1% RH, the solar radiation data is 1 W/m², the wind speed data is 0.1 m/s, and the precipitation data is 0.1 mm. This high-resolution data is invaluable for identifying even the slightest trends and potential failure points, allowing for a more accurate assessment of trim part performance.
