ASTM G155 Standard Practice for Operating Xenon Arc Light Apparatus for Exposure of Non-Metallic Materials
The ASTM G155 procedure outlines fundamental principles and operational steps for utilizing xenon arc light and water apparatus. It is designed to simulate the weathering effects experienced by materials when exposed to sunlight, either directly or through window glass, and moisture from rain or dew. It is aimed at replicating real-life conditions and is focused on procedures for obtaining, measuring, and regulating exposure conditions.

ASTM G155 Introduction
ASTM G155 outlines how to use Xenon Arc Light Apparatus to test non-metallic materials’ durability under simulated outdoor weather conditions in a controlled lab. This involves exposing the materials to xenon arc light radiation, regulated temperature, and moisture levels. The test helps evaluate how well materials hold up against environmental stressors, improving their performance.
G155 Standard Test Method
Mounting Tests Specimens
The specimens are attached to specimen holders
Exposure
The G155 specimens are exposed to the specified test conditions
Repositioning of the Specimens
Repositioning specimens during exposure isn’t required if the irradiance at positions farthest from the center of the specimen area is at least 90% of that measured at the center. The uniformity of irradiance is determined.
G155 Equipment and Sample Preparation
Specimen Detail
Non-metallic materials are used as specimens for exposure to the xenon arc lamp.
Specimen Size
Each G155 test specimen is identified by a suitable indelible marking, excluding areas designated for testing. The property of the test specimens to be evaluated will be determined. Before exposing the specimens, the relevant properties are quantified according to recognized international standards.
G155 Test Result and Interpretation
ASTM G155 apparatus is designed to simulate the conditions experienced in real-world usage, including the effects of sunlight, moisture, and heat, to induce property changes in the tested materials.

Tests Related to G155 Standard
ASTM G155 is related to tests, including ASTM D3980 for paint testing, ASTM G26 for operating Xenon arc, and ASTM G113 for weathering tests.
Use of G155 in Various Industries
It is one of the widely used standards by automotive, construction, textiles, and packaging industries for simulating sunlight, heat, and moisture effects on non-metallic materials, which assures durability, weathering performance, and colorfastness under simulated outdoor conditions.
Materials Commonly Tested with G155
The standard is used in the testing of nonmetallic materials such as plastics, paints, coatings, textiles, and rubber in regard to degradation using xenon arc light, looking into their resistance to fading, discoloration, cracking, UV-sensitive films, and weather-resistant textiles.
Common Challenges and Troubleshooting in G155 Testing
Testing faced challenges of uniform sample exposure, consistent environmental conditions, and proper interpretation of results. Issues such as misalignment or temperature fluctuations can lead to inconsistent data. Troubleshooting includes calibrating apparatus, monitoring filters, and ensuring sensor accuracy.
Safety and Best Practices in G155 Testing
A Xenon arc light apparatus must be handled under strict safety measures, including UV-proof gear and heat-resistant gloves, regular maintenance, examination of safety interlocks, and proper disposal of consumables. Strict adherence to the manufacturer’s guidelines about operation and calibration minimizes risks and ensures accurate tests.
Importance of G155
It is a vital standard for predicting the longevity and performance of outdoor materials. It will help manufacturers design products that last. It provides a standardized method for evaluating degradation, improving product quality, reducing failures, and enhancing consumer confidence.
