Aluminum-plastic panel is a kind of commonly used building decoration material, which is composed of aluminum alloy and plastic. In outdoor environments, aluminum-plastic panels are subject to ultraviolet light, climate change, and other environmental factors, which may lead to color fading, surface flour, oxidation, and reduced weather resistance.

The UV aging test chamber can simulate the solar UV radiation and other climatic conditions, and evaluate the weather resistance and stability of aluminum plastic panels by accelerating the aging process.

Method of test
Specific test steps of UV aging test chamber in the application of aluminum plastic plate:

Material selection and preparation: Select the aluminum plastic plate material that meets the requirements. Aluminum plastic plate is composed of aluminum alloy and plastic composite, should choose a certain thickness and specifications of the standard sample.

Set test conditions: according to the test requirements, determine the UV radiation source, temperature, humidity and radiation time in the test chamber and other parameters. These conditions should be able to simulate real UV radiation and climate conditions such as sunlight exposure, high temperature, humidity, etc.

Mounting sample: Fix the aluminum-plastic plate sample on the sample table of the test chamber to ensure that the sample surface is exposed to ultraviolet light source. Different installation methods can be selected, such as horizontal placement or inclined installation, to simulate the actual use situation.

Start the test: Start the UV aging chamber and expose the sample to simulated UV radiation. According to the set test conditions, radiation for a certain time. At the same time, humidity and heat cycling can be selectively carried out to simulate the real climate environment.

Monitoring and recording: Regularly monitor and record the performance changes of aluminum plastic plate samples. Appropriate instruments and equipment can be used, such as color difference meter, surface flour evaluation instrument, adhesion tester, etc., to measure and record the color change, surface flour degree, adhesion and gloss of aluminum plastic plate.

Evaluation results: According to the test data and evaluation indicators, the aging degree and performance changes of aluminum plastic plate samples were analyzed. The differences between the different test samples were compared to evaluate the weatherability and stability of the aluminum-plastic panel.

Interpretation of results: According to the test results, the weatherability and life expectancy of aluminum plastic panels were evaluated. To determine the material optimization scheme and improvement measures to improve the weatherability and long-term service performance of aluminum plastic panels.

Testing by UV aging test chamber can provide reliability assessment of aluminum-plastic panel materials, guide manufacturers and users to select appropriate aluminum-plastic panel materials, and ensure their durability and stability in outdoor environments.

Industry standards
In the UV aging test of aluminum plastic panels, the following industry standards can be referred to:

ASTM G155: “Standard Practice for Operating Xenon Arc Light Apparatus for Exposure of Non-Metallic Materials”

ASTM G155 is a standard published by the American Society for Materials and Testing (ASTM) for the operation of xenon lamp radiation equipment for exposure testing of non-metallic materials, including aluminum and plastic sheet materials. This standard can be used to evaluate the weatherability of aluminum plastic panels under ultraviolet radiation.

ISO 4892-2: “Plastics — Methods of exposure to laboratory light sources — Part 2: Xenon-arc lamps”

ISO 4892-2 is a standard published by the International Organization for Standardization (ISO) dealing with methods of exposure of plastic materials to laboratory light sources, which include xenon lamps. Some of the test methods in this standard can be applied to the UV aging test of aluminum plastic panels.
