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:

Pre-treatment: After the samples are cleaned, equilibrate them at 232 and 50% RH for 24 hours.

Initial chromaticity measurement: Use a colorimeter to record the initial Lab value (or YI yellowing index).

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).

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).
