ASTM G155 is the basic method for evaluating the resistance of materials to the harshest environmental and solar exposure conditions. The standard uses a xenon lamp light source to rapidly simulate the effects of solar UV, such as light intensity, humidity, and heat, which can lead to a loss of aesthetics in non-metallic materials.

SONACME Technology is proud to offer xenon test chambers that comply with the ASTM G155 standard. With ASTM G155 testing, we can realistically simulate the effects of accelerated aging caused by UV radiation, either outdoors or through a window.

ASTM G155 is used to age a wide range of products in a variety of industries, including the automotive industry, surface coatings, pharmaceutical light stability testing, printing inks, roofing, rubber, adhesives, automotive, textiles, geotextiles, and more.

This method repeatedly exposes the sample to a filtered xenon arc, simulating different conditions depending on the filter used. Depending on the conditions you wish to simulate, humidity and in some cases rainwater cycles that simulate watering are also combined with the exposure, all in a controlled environment.

There are many practical advantages to using ASTM G155. It allows us to predict how materials and products will react when exposed to sunlight for extended periods of time, which is critical to maintaining their aesthetics, durability, and real-world performance. In addition, it helps to establish robust specifications and performance standards for a wide range of industries, increasing consumer confidence and satisfaction with products that have undergone these in-depth tests.

SONACME Technology's self-developed and manufactured xenon test chambers meets the test requirements of the ASTM G155 test standard, including:

• Overall exposure time (hours) (for simulating indoor/outdoor conditions)

• Lamp filters

• Lamp irradiance levels

• Type and duration of moisture exposure

• Duration of light and moisture exposure

• Temperature of light exposure

• Temperature of humidity exposure

• Duration of light/dark cycle

In addition to meeting the ASTM G155 test standard, SONACME Technology's xenon test chambers also complies with several ASTM test methods. These include ASTM D2565, ASTM D4459 and ISO 4892.
