xenon lamp

By using artificial light sources to generate radiation similar to sunlight, and under corresponding temperature, humidity, and spray conditions, the product is subjected to accelerated simulated weather resistance testing to obtain the weather resistance performance of the material in a short period of time

 

Xenon lamp aging test
Test purpose
By simulating the radiation of sunlight, combined with temperature, humidity, and spray conditions, accelerated weather resistance testing is conducted on the product to quickly evaluate the weather resistance performance of the material under the combined effects of light, temperature, humidity, and water spray.

 

Test Standard
According to the standard:

ISO 4892-2: Plastic laboratory light source exposure method (xenon arc lamp)

ASTM G155: Xenon Arc Lamp Exposure Test for Non Metallic Materials

SAE J2527: Xenon Arc Lamp Aging Test for Automotive Materials

 

Test Principle
Xenon lamp aging test uses xenon arc lamps to simulate solar spectra (including ultraviolet, visible, and infrared), combined with temperature and humidity control and spray systems, to accelerate the material aging process and evaluate the durability of materials in outdoor environments.

test equipment
 

Xenon lamp aging test chamber

Xenon arc lamp (simulating solar spectrum)

Filter system (simulating sunlight or filtering sunlight through window glass)

Temperature and humidity control system

sprinkler system

Irradiance meter

Sample holder

Assessment tools (colorimeter, gloss meter, microscope, etc.)

 

Test steps
Sample preparation:

Clean the surface of the sample to ensure that there are no oil stains or other contaminants.

Record the initial state of the sample (taking photos, measuring color difference, measuring glossiness, etc.).

Fix the sample inside the test chamber, ensuring that the exposed surface faces the light source.

Test condition settings:

Light source: Xenon arc lamp, simulating solar spectrum.

Filter system:

Sunlight simulation: using a daylight filter.

Window glass filtering sunlight simulation: Use window glass filters.

Irradiance: typically 0.35-1.20 W/m ² @ 340 nm (according to standards or requirements).

Temperature inside the box: Set according to demand (usually 40-70 ℃).

Blackboard temperature: Set according to requirements (usually 50-90 ℃).

Relative humidity: Set according to demand (usually 10-75%).

Spray conditions: Set the spray cycle according to the demand (such as spraying for 18 minutes and stopping spraying for 102 minutes).

Testing cycle: Depending on the requirements, it usually ranges from several hundred hours to several thousand hours.

 

Test Run:

Start the test chamber and maintain the set conditions.

Regularly check irradiance, temperature, humidity, and sprinkler system to ensure stable testing conditions.

Record environmental data during the testing process.

Test completed:

Take out the sample and restore it to a standard environment for 24 hours.

Record the status of the sample after testing (taking photos, measuring color difference, measuring glossiness, etc.).

Result evaluation:

Appearance changes:

Check whether the sample has discoloration, powdering, cracks, bubbles, and other phenomena.

Measure the color change (Δ E value) using a colorimeter.

Glossiness variation:

Measure surface glossiness changes using a glossiness meter.

Mechanical performance changes:

Evaluate the changes in properties such as tensile strength and impact strength of materials.

Microstructure analysis:

Observe surface microstructural changes using a microscope.

 

Precautions
Regularly calibrate xenon arc lamps and irradiance meters to ensure light source stability.

Ensure uniform exposure of the sample and avoid local overheating or insufficient lighting.

After the test is completed, the sample needs to be restored to a standard environment before evaluation.

 

Test Record
Record the testing conditions (light source type, irradiance, temperature, humidity, spray cycle, testing cycle, etc.).

Record the initial and post test states of the sample (photography, color difference measurement, glossiness measurement, etc.).

Record the specific manifestations of material performance changes.

 

Conclusion
Based on the test results, evaluate the weather resistance of the material in the xenon lamp aging environment and issue a test report. This test can provide important basis for material selection, product design, and improvement.
