Product Description
I. Equipment core functions and application scenarios
Application Scenarios:
-
Material weathering test: simulate the anti-yellowing ability of materials (plastics, rubber, paint, textiles, etc.) under the action of light, temperature and humidity in a low wind speed natural ventilation environment.
-
Automotive interior testing: evaluate the color stability of dashboard and seat fabrics in a long-term ventilation environment.
-
Outdoor building materials verification: e.g. door and window seals, outdoor furniture aging resistance in a breezy environment.
Core functional modules:
Module
Technical Requirements
Role Description
Low wind speed circulation system
Wind speed range: 0.1~2m/s (adjustable), uniformity deviation 10%
Simulate the natural breeze environment, avoid strong wind to interfere with the aging mechanism
Lighting system
Xenon lamp/UV lamp (0.5~1.2W/m @340nm), spectrally matched to daylight.
Trigger the photo-oxidation reaction of the material to accelerate the yellowing process.
Temperature and humidity control
Temperature: 20~80, Humidity: 10%~90% RH
Simulates hot and humid or dry climatic conditions
Sample holder and rotation system
Multi-angle adjustable, support sample rotation (1~5rpm)
Ensure light and ventilation uniformity
Yellow colorimetric detection
Integrated colorimeter (E0.1) or spectrophotometer interface
Real-time monitoring of color difference changes (e.g. Lab value, YI yellowing index)
Data management system
The software automatically records the time-yellowing curve and supports the export of PDF reports.
Meet the data traceability requirements of ISO/ASTM standards
Second, the test standard and typical process
Applicable standards:
-
ISO 4892-2: Laboratory light source exposure test for plastics (Xenon lamp method).
-
ASTM G155: Xenon lamp aging test for non-metallic materials.
-
GB/T 14576: Test method for light yellowing resistance of textiles.
-
Enterprise standards: such as automobile OEM interior trim parts yellowing resistance test specification.
Example of test procedure:
1.
Pre-treatment: After the samples are cleaned, equilibrate them at 232 and 50% RH for 24 hours.
2.
Initial chromaticity measurement: Use a colorimeter to record the initial Lab value (or YI yellowing index).
3.
Test phase:
Condition setting: light intensity 0.8W/m @340nm, temperature 60, humidity 50% RH, wind speed 0.5m/s.
Cycle mode: light (8h) dark (4h) repeat to set cycle (e.g. 500h).
4.
Result evaluation:
Color difference E: E1.5 is qualified (some automotive standards require E1.0).
Yellowing Index YI: YI change value 3 (e.g. white material).
