ASTM G155

Standard Method for Using Xenon Arc Lamp Apparatus for Exposure of Non-Metallic Materials

ASTM G155 is an essential method for evaluating the resistance of materials to the most rigorous environmental and solar exposure conditions. Using a xenon light source, this standard rapidly simulates the UV effects of the sun, such as light intensity, humidity, and heat that can lead to a reduction in the aesthetic qualities of non-metallic materials.

Micom Laboratories is proud to offer testing services in accordance with ASTM G155, which is titled ‘Practice for Operating Xenon Arc Light Apparatus for Exposure of Non-Metallic Materials.’ This method is the cornerstone of many standards related to accelerated aging by solar ultraviolet radiation. ASTM G155 and other standards derived from it cover a wide range of products and applications. To view a product category list, refer to our dedicated Xenon Arc Testing section. ASTM G155 tests allow us to faithfully replicate the effects of accelerated aging due to UV radiation, whether outdoors or through a window.

Uses and Benefits of ASTM G155

ASTM G155 - Accelerated Weathering

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

This method exposes samples to repeated cycles of exposure to a filtered xenon arc, simulating different conditions depending on the filters used. Depending on the conditions you wish to simulate, humidity, and in some cases, a rain cycle simulating watering will also be combined with the exposure, all within a controlled environment.

The Practical Benefits

Using ASTM G155 offers many practical advantages. This method allows us to predict how materials and products will react to prolonged exposure to sunlight, which is vital for maintaining their aesthetics, durability, and real-life performances. Furthermore, it facilitates the establishment of robust specifications and performance standards for a variety of industries, enhancing consumer confidence and satisfaction in products subjected to these in-depth tests.

Experimental Parameters and Implementation of ASTM G155

To perform a relevant accelerated weathering test that is right for your application the following test parameters need to be defined carefully:

  • Overall exposure duration (hours) (used to simulate indoor/outdoor conditions)
  • Lamp filters
  • The lamp irradiance level
  • The type and duration of moisture exposure
  • The timing of the light and moisture exposure
  • The temperature of light exposure
  • The temperature of moisture exposure
  • The timing of a light/dark cycle.

There are predefined cycles in Table X3.1 of ASTM G155 that can be used when doing xenon arc testing. Please feel free to contact us if you need guidance in deciding which test cycle or test conditions to use for your specific needs. Our experts will be happy to assist you in obtaining the best accelerated weathering test possible.
