Test Procedures

Sample Loading: Secure specimens to the sample holder. If the sample space is not fully occupied, fill with spacers to maintain stable chamber pressure and humidity.

Lamp Verification: Install UVA or UVB lamps according to standard requirements and confirm cumulative operating time.

Cycle Setup: Configure light intensity, temperature, duration, and condensation/spray cycle intervals in the controller.

Test Initiation: Verify water flow is unobstructed, start the equipment, and the instrument enters automatic cyclic testing mode.

Process Monitoring: Periodically review irradiance readings and operational data logs.

Rating Comparison: After testing concludes, remove samples and assess aging severity through visual color difference comparison, physical tensile strength testing, or chalking grade evaluation.

Maintenance Information

Lamp Replacement: Replace lamps sequentially every 1600-2000 hours to maintain stable irradiance energy.

Water System Cleaning: Use only deionized or distilled water. Clean the water tank regularly to prevent scale buildup that may shorten heating element lifespan.

Sensor Calibration: Calibrate the irradiance sensor every six months to ensure internationally valid test data.

Environmental Ventilation: The test chamber generates heat and should be placed in a well-ventilated area. Clean the intake air filter regularly.
