ASTM G154 Standard Practice for Operating Fluorescent Ultraviolet (UV) Lamp Apparatus for Exposure of Materials
ASTM G154 establishes unified operation, measurement and control rules for fluorescent UV accelerated weathering chambers, to simulate outdoor aging damage caused by solar UV, heat and moisture (dew/rain) on non-metallic materials.
It only defines equipment operation procedures, and must be paired with material-specific standards to set exposure cycles and property evaluation rules; it cannot generate standalone test conclusions. Not applicable for bare metal corrosion testing.
ASTM D4329 covers specific procedures and test conditions based on practices ASTM G151 as well as ASTM G154. ASTM D4329 also covers the preparation of test specimens, the test conditions best suited for plastics, and the evaluation of test results.
ASTM D4329 useage:
Polymers can have their mechanical, electrical and optical properties significantly altered when exposed under outdoor conditions such as light, heat and water. This method is intended to prompt property changes associated with end-use conditions, including the effects of daylight, moisture in addition to heat. The simulation of the deterioration provoked by localized weather, such as, atmospheric pollution, biological attack, and saltwater exposure is not intended by the exposure used in this practice. For a combination of fluorescent light exposure and salt water, you should consider ASTM D5894.
