ActivePlastics - Determination of the ultimate aerobic biodegradability in soil by measuring the oxygen demand in a respirometer or the amount of carbon dioxide evolved
土壤中塑料材料最终需氧生物分解能力的测定 采用测定密闭呼吸计中需氧量或测定释放的二氧化碳的方法
Application Summary AI generated
This standard specifies a test method for determining the ultimate aerobic biodegradability of plastic materials in soil under laboratory conditions. It is applied by measuring either the oxygen demand in a closed respirometer or the amount of carbon dioxide evolved, simulating natural soil environments. The standard is used for evaluating the environmental fate of plastics, particularly for products marketed as biodegradable in soil, such as agricultural mulching films or compostable packaging.
