ASTM G155 Test

The purpose of ASTM G155, Xenon Arc Exposure testing for Non-Metallic Materials is to describe the basic operating procedures for a xenon arc test chamber used to simulate the abrasion effects of sunlight, humidity, and heat.

ASTM G155 Test

ASTM G155 is an application for operating xenon arc light apparatus for exposure of non-metallic materials. This practice is the basis for all other standards for accelerated aging that use Xenon Arc UV light sources to simulate exposure to natural sunlight on an accelerated basis. Many standards call this practice.

Testing ASTM G155 allows to reproduce the effects of weathering that occur when materials are exposed to sunlight (directly or through window glass) and moisture. 

ASTM G155 outlines best practices for xenon arc testing, an aging test best performed on non-metallic materials made for outdoor, bright light uses. Similar to ASTM G154 - another popular type of weatherproofing test. However, the G154 test uses fluorescent lights to simulate outdoor weather conditions, while the G155 test uses xenon arc lamps.

Xenon arc lamps pass electricity through ionized xenon gas to produce light and are known for their ability to mimic all the effects of natural sunlight. Because xenon lamps simulate sunlight so well, ASTM G155 is the best choice of the two tests for outdoor products.

The G155 standard does not specify any way to test a material. However, xenon arc exposure typically involves repeatedly switching between cycles of light and humidity in a controlled in vitro environment.

ASTM G155 is used to perform accelerated aging in a wide variety of products and industries, including the automotive industry, surface coatings, pharmaceutical light stability tests, printing inks, roofing, rubber, adhesives, textiles, geotextiles, and others.

When testing your products using this app, samples are exposed to repetitive cycles of light and humidity under controlled environmental conditions. Moisture is usually produced by spraying the test sample with demineralized water or by condensing water vapor onto the sample.

ASTM G155 Experimental Parameters

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

  • Overall exposure time (hours) (used to simulate indoor/outdoor conditions)
  • lamp filters
  • Lamp brightness level
  • Type and duration of exposure to moisture
  • Timing of exposure to light and moisture
  • light exposure temperature
  • Moisture exposure temperature
  • Timing of a light/dark cycle.
