ActivePlastics—Determination of the degree of disintegration of plastic materials under simulated composting conditions in a laboratory-scale test
塑料 在实验室规模模拟堆肥化条件下塑料材料崩解率的测定
Application Summary AI generated
This standard specifies a laboratory-scale test method for determining the degree of disintegration of plastic materials under simulated composting conditions. It is applied in the plastics industry to evaluate the biodegradability of plastics, such as packaging films or compostable bags, by measuring their physical breakdown in a controlled composting environment. The results help manufacturers and regulators assess whether a material meets requirements for industrial composting facilities.
