Objectives of ASTM G155 Testing
The objectives of ASTM G155 focus on evaluating how materials respond to long-term environmental exposure. This section outlines how the standard aids quality control to achieve product excellence and market readiness.
- Ensuring Product Longevity: The test simulates solar radiation, UV exposure, and moisture, allowing manufacturers to predict degradation over time. This enables them to design materials that withstand real-world conditions, reducing the risk of premature failure.
- Achieving Regulatory Compliance: ASTM G155 testing ensures that products meet stringent international safety and quality standards. This compliance facilitates smoother market entry and reduces the likelihood of costly product recalls or trade restrictions.
- Optimising Product Development: By evaluating materials under simulated conditions, companies gain valuable insights to refine product formulations. This data supports innovation while controlling costs, enhancing both quality and efficiency in development cycles.
Industry Applications and Product Relevance
Various industries rely on ASTM G155 testing to verify product durability under simulated sunlight and environmental stressors. Below is a table summarising key applications and relevant standards.
| Industry | Product Applications | Relevant Standards | Testing Focus |
|---|---|---|---|
| Automotive | Vehicle paints, trims, interior components | ASTM G155, ASTM D7869 | UV stability, color retention, resistance to cracking |
| Construction | Exterior coatings, roof membranes, paints | ISO 4892-2, ASTM G155 | Adhesion, colorfastness, gloss retention |
| Consumer Goods | Outdoor furniture, signage, plastic products | ASTM G154 (UV-specific), ASTM D2565 | Structural integrity, prevention of fading |
For products like automotive paints and trims, compliance with ASTM G155 ensures that materials maintain their appearance and structural integrity under UV exposure and heat. Similarly, ISO 4892-2 supports long-term durability evaluations for exterior coatings and plastics in construction projects.

Core Testing Procedures and Methodology
The ASTM G155 standard defines procedures to expose materials to controlled xenon arc light, temperature, and moisture. These steps ensure reproducibility and accuracy in testing.
- Xenon Arc Exposure: Xenon arc lamps provide full-spectrum light to simulate natural sunlight, including UV, visible, and infrared radiation. This is crucial for materials like automotive coatings that face prolonged sunlight exposure.
- Controlled Environmental Conditions: The test regulates temperature and humidity to reflect various climatic conditions. This helps evaluate how materials behave when subjected to both UV exposure and fluctuating moisture levels.
- Customisable Test Cycles: Test cycles incorporate light and dark phases, with optional water spray intervals to replicate real-world weathering. Companies can tailor these cycles to match the performance criteria of specific products.
Our laboratories at 4ward Testing offer customisable testing protocols to ensure that each material is evaluated under relevant conditions, optimising data accuracy for decision-making.
