ASTM G152 Standard Practice for Operating Open-Flame Carbon Arc Light Apparatus for Exposure of Non-metallic Materials
This practice outlines the fundamental principles and operational steps for employing open-flame carbon-arc light and water apparatus. Its purpose is to simulate the weathering effects experienced by materials when exposed to sunlight and moisture, such as rain or dew, in real-world scenarios. The focus of this practice is on establishing, measuring, and regulating exposure conditions. While various exposure procedures are provided in an appendix, it does not prescribe the ideal exposure conditions for specific materials under test.

ASTM G152 Introduction
Employing this apparatus replicates property alterations that materials undergo in actual usage conditions, including the impact of sunlight, moisture, and heat. MaTestLab is one of the best testing service providers, with the best network of testing laboratories in the USA to carry out ASTM G152 tests for our clients. Moisture introduction to the test specimen may be facilitated during these exposures.
ASTM G152 Test Method
Light and moisture cycles
In ASTM G152, specimens are subjected to repeated cycles of light and moisture in controlled environmental settings. Moisture is typically generated either by spraying the test specimen with demineralized water.
Exposure conditions
Exposure conditions can be adjusted by selecting lamp filters, controlling the lamp’s irradiance level, choosing the type of moisture exposure, timing the light and moisture exposure, and scheduling light and dark cycles.
G152 Equipment and Sample Preparation
Specimen Detail
The exact shape and dimensions of the specimens to be exposed are determined by the specific test procedure used for measuring the property of interest. The specimens mustn’t be cut from exposed materials.
Specimen Size
Non-destructive tests typically require a minimum of three specimens, whereas destructive tests necessitate at least six specimens to measure properties following exposure.
G152 Test Result and Interpretation
ASTM G152 is a standard practice for operating open flame carbon arc light apparatus for exposing non-metallic materials. This practice provides test procedures for subjecting materials to open flame carbon arc light and water, mimicking outdoor weathering effects. The test results help evaluate the performance of materials and coatings when exposed to sunlight and moisture.

Tests Related to ASTM G152
ASTM G152 is related to tests including ASTM D3980 for interlaboratory testing of paint, ASTM E691 for determining test precision, and ASTM G113 for natural and artificial weathering tests of non-metallic elements.
Use of G152 in Various Industries
It is one of the widely used standards in the automotive, construction, aerospace, and consumer goods manufacturing industries to assess the durability and weathering resistance of non-metallic materials to ensure their performance and integrity under environmental stressors.
Materials Commonly Tested with G152
It tests nonmetallic materials like paints, coatings, and plastics in an accelerated weathering in an open-flame carbon arc light apparatus and is essential to most outdoor products such as building materials and furniture.
Safety and Best Practices in G152 Testing
Testing is safety-sensitive, as it has high-intensity light and elevated temperatures. Safety measures include proper ventilation, PPE, calibration, and handling of materials. Best practices in sample preparation, test duration, and periodic monitoring for consistent results.
Importance of G152
The standard is important for predicting material degradation over time, improving formulations, and enhancing product longevity. It helps manufacturers mitigate product failure risks, reduce warranty claims, and ensures compliance with industry regulations in various applications.
