UpcomingPlastics—Determination of specific aerobic biodegradation rate of solid plastic materials and disappearance time (DT50) under mesophilic laboratory test conditions
塑料 中温实验室试验条件下固体塑料材料的特定需氧生物分解率和消失时间（DT50）的测定
Application Summary AI generated
This standard specifies a laboratory test method for measuring the specific aerobic biodegradation rate and the time required for 50% of a solid plastic material to disappear (DT50) under controlled mesophilic conditions. It is applied in the plastics industry for assessing the biodegradability of solid plastic products, such as packaging films or agricultural mulch, in environments like soil or compost at moderate temperatures. The standard is used by manufacturers and testing laboratories to evaluate and compare the environmental degradation performance of plastic materials.
