Test Procedures
1. System Initialization
Power on the instrument and the computer. Allow the xenon arc lamp to stabilize for the recommended warm-up period to ensure consistent irradiance output. Launch the analysis software and select the desired testing standard (e.g., GB/T 18830).
2. Calibration and Zeroing
Perform a baseline scan with an empty sample holder to calibrate the system's $100\%$ transmittance reference. This compensates for ambient conditions and current lamp intensity.
3. Sample Preparation and Loading
Cut the textile sample into the required dimensions, ensuring it is flat and free of wrinkles. Place the sample into the holder. The automatic X-Y positioning system will align the sample for the first measurement point.
4. Measurement and Data Acquisition
Initiate the scan. The instrument will measure the spectral transmittance at specified intervals (e.g., $2\text{ nm}$) across the $290\text{--}400\text{ nm}$ range. The software will repeat this process for different points on the fabric as required by the standard.
5. Report Generation
The software automatically calculates the mean UPF value, UVA transmittance, and UVB transmittance. You can then save the data to the database and print the standardized test report.
