Lamp Anti-aging Test Chamber
The Lamp Anti-Aging Test Chamber is a high-performance laboratory instrument designed to evaluate the yellowing resistance and cold durability of a wide range of materials, including finished shoes, rubber, plastics, outsoles, synthetic leather, and other polymer-based products. By simulating prolonged exposure to ultraviolet (UV) light and low temperatures, this chamber allows manufacturers to assess how their products behave under real-world environmental stress.
Constructed with SUS 304 stainless steel, the chamber is corrosion-resistant, durable, and capable of supporting multiple fixtures to accommodate different material types and test protocols. It is an essential tool for footwear manufacturers, polymer material laboratories, and quality control centers seeking to ensure long-term product reliability and maintain compliance with international standards.
Application Scenarios
The Lamp Anti-Aging Test Chamber is widely applied across industries where material performance under cold conditions and UV exposure is critical:
Footwear Manufacturing: Evaluates yellowing and cold resistance of shoe uppers, soles, and insoles to ensure durability and appearance in low-temperature climates.
Rubber and Plastic Products: Tests for UV-induced discoloration and brittleness, helping manufacturers optimize formulations for outdoor or cold-weather applications.
Synthetic Leather and PU Materials: Assesses color stability and mechanical properties to maintain product aesthetics and functional performance.
Polymer Components and Accessories: Measures resistance to environmental aging, ensuring compliance for consumer goods, sports equipment, and industrial applications.
R&D Laboratories and Quality Control: Provides controlled conditions for material aging studies, batch testing, and product certification.
This chamber is also ideal for research on environmental stress resistance, helping R&D teams design longer-lasting materials and footwear products capable of withstanding harsh climates.
Compliant Standards
The Lamp Anti-Aging Test Chamber is designed to comply with internationally recognized standards for UV and yellowing evaluation:
| Standard | Description |
|---|---|
| GB/T 250 | Gray Scale for Assessing Change in Color, used to evaluate yellowing post-test |
| ASTM D1148 | Rubber deterioration — UV light and ozone yellowing test |
| ISO 105-B02 | Textiles — Tests for color fastness to light (simulated UV exposure) |
| QB/T 2726 | Footwear materials — Yellowing resistance assessment method |
| GB/T 24128 | Plastics — Determination of yellowing resistance under laboratory light sources |
Compliance with these standards ensures that your material testing results are reliable, repeatable, and internationally recognized.
Test Procedure
Power On & Time Setting: Switch on the chamber and program the desired test duration using the electronic timer.
Sample Placement: Place samples flat on the tray with the positive side facing upward, avoiding curling or folding.
Start Test: Press the start button to initiate UV yellowing exposure. The system will run for the preset duration, after which an alarm will sound.
Cooling: Remove samples and allow them to cool naturally before assessment.
Color Evaluation: Place cooled samples in a D65 standard light source box to compare them with untreated reference samples.
Grading Yellowing: Use the GB/T 250 Gray Scale to evaluate yellowing levels from Level 1 to Level 5.
Test Duration Options: Standard test cycles include 24, 48, or 96 hours, or custom durations as required by the user or testing standard.
This process ensures accurate and consistent assessment of material aging and yellowing behavior.
