UV accelerated aging test chamber

UV accelerated aging test chamber

Sonacme provides UV aging test chamber required for UV accelerated aging test. Uv exposure can be through direct exposure (i.e. outdoor exposure) or through glass exposure (i.e. indoor exposure). There are many test methods and two main practices for accelerated UV testing. Among them, Sonacme provides UV aging test chambers for the following test methods and practices and many other methods:

UV test standard:

ASTM G154 Standard operating practice for operating fluorescent ultraviolet (UV) lamp instruments for exposure of non-metallic materials

ASTM G155 Standard Operating Procedure for xenon arc lamp instruments for exposure to non-metallic materials

ASTM D7869 Standard Operating Procedure for Enhanced light and water xenon arc exposure tests for Transporting coatings

ASTM D2565 Standard Operating Procedure for xenon arc Exposure of plastics for outdoor applications

ASTM D5208 Standard Operating Procedure for xenon arc Exposure of plastics for outdoor applications

Applications and considerations for UV testing:

The ultimate goal of UV testing is to "compress time" so that we can know how the product will react as it is exposed to more and more sunlight. To do this, we need to accelerate the simulation of sunlight; This process is called accelerated weathering. As with any other accelerated aging process, our goal is to perform the best simulation at the fastest aging rate possible without causing reactions that would not occur under normal exposure conditions.

At present, two kinds of ultraviolet aging equipment are commonly used: xenon arc lamp and fluorescent lamp: xenon lamp aging test chamber and UV ultraviolet light aging test chamber. Each technique has its own advantages and disadvantages, and each technique can be used in a variety of test conditions, which can greatly change the test results. The xenon arc test is primarily used to assess the change in color/appearance of indoor/outdoor UV light over a period of time, either directly or through glass (indoor conditions).

ASTM G-155

Fluorescent lamp accelerated aging test (UV aging test chamber) is mainly used to evaluate the mechanical properties after exposure. This technique is used for comparison/authentication purposes. However, the scientific literature clearly shows that this technique, despite its versatility, has poor time prediction capabilities. For more information on this test method, please refer to ASTM G-154.

Sonacme also offers ultraviolet (UVC) exposure -UVC UV aging test chamber for surfaces used in medical environments. UVC exposure is commonly used for hygienic treatment in medical Settings. In addition to UV aging tests, you can also learn about our range of accelerated aging test chambers for coatings, paints and polymers. Please feel free to contact us.
