Accelerated aging tests have always played a crucial role in the field of material science, especially for the aging research of outdoor construction materials such as asphalt. Sonacme's xenon lamp aging tester shows excellent performance in simulating the durability test of materials under natural environment conditions. In this article, we will take the ASTM D4798 standard - accelerated aging test conditions and test procedures for asphalt materials (xenon arc method) as the benchmark, and discuss how Sonacme Technology's xenon lamp aging tester perfectly meet this international standard.

ASTM D4798 standard interpretation:

The ASTM D4798 standard specifies the conditions and procedures for accelerated aging tests of asphalt materials under xenon arc lamps, aiming to quickly assess the durability and stability of asphalt materials by simulating natural light and temperature conditions. The standard details key parameters such as the type of light source, black panel temperature, lamp irradiance, dry bulb temperature, etc. to ensure the accuracy and repeatability of test results.

Overview of Sonacme Technology desktop xenon lamp aging tester:

Sonacme Technology's xenon lamp aging tester adopts advanced xenon arc light source technology, which is able to highly simulate the ultraviolet, visible and infrared light in the solar spectrum, providing accurate environmental simulation for material aging research. The tester can also adjust the light source intensity and other parameters according to user needs to meet the accelerated aging test needs of different materials.

Fitting analysis:

Light source technology:

Sonacme 's xenon aging tester adopts 1.8KW imported air-cooled xenon lamps or 1.8KW domestic xenon lamps, whose spectral distribution is highly similar to that of sunlight, and is able to accurately simulate the ultraviolet, visible and infrared light radiation under natural lighting conditions. This feature is highly compatible with the requirements of ASTM D4798 standard for light sources, ensuring the accuracy and authenticity of the test environment.

Parameter adjustability:

Irradiance monitoring mode: 340nm or 420nm or 300nm ~ 400nm (choose one before ordering)

Irradiance adjustable range: 30W / M2 ~ 150W / M2 (full-spectrum 300-400nm), 0.3W / M2 ~ 1.5W / M2 @340nm, 0.5W / M2 ~ 2.7 W / M2 @420nm.
