Accelerated weathering to simulate the damaging effects of long-term outdoor exposure of polymer materials according to ASTM G154, ASTM D4329, ASTM D4587, ISO 4892, SAE J2020.
All of Q-Lab’s panel holders are designed to meet the requirements of ASTM G154 and other international standards. The QUV chamber can accommodate a variety of sample types, but three principles should be considered when mounting odd-shaped specimens:
ASTM G154 is an accelerated UV ageing test using Specific Fluorescent lights to simulate the impact of sun exposure on paints, coatings and polymers.
By the end of the article, you will know what ASTM G154 is all about, when you should use it, and what to do once you have completed the testing process. What is ASTM G154? ASTM G154 is an American standard for measuring accelerated weather testing.
Intertek performs weathering testing on automotive materials and components, such as plastics and composites. Testing is performed against international and OEM-specific standards. (Automotive) Weathering testing standards include. QUV: ISO 4892-2, ASTM G154, ASTM D4329, ASTM D4587, SAE J2020.
Q-Lab’s UVA-340, UVA-351, and UVB-313EL lamps all meet the specifications of both ASTM G154 and ISO 4892-3 for Daylight, Window, and Extended UV. The following Q-Lab UV filters used in Q-SUN weathering testers meet the spectral requirements specified in ASTM G155 and ISO 4892-2.
The method is intended to reproduce the weathering effects that occur when the material is exposed to either solar radiation through glass (indoor conditions, ASTM D4459, Q-Sun) or to sunlight and moisture as rain or dew (outdoor conditions, ASTM G154, Cycle 1, QUV).
