ActivePlastics—Artificial weathering including acidic deposition
塑料 含酸性沉积的人工气候老化
Application Summary AI generated
This standard specifies a laboratory test method for evaluating the resistance of plastics to artificial weathering that includes the effects of acidic deposition, such as acid rain. It is applied in the plastics industry for quality control and material selection, particularly for products intended for outdoor use in environments with high atmospheric acidity. The testing context involves exposing plastic specimens to controlled cycles of ultraviolet radiation, temperature, moisture, and acidic spray to simulate long-term environmental degradation.
