ActiveDetermination of the ultimate aerobic biodegradability of plastic materials in an aqueous medium--Method by measuring the oxygen demand in a closed respirometer
水性培养液中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的方法
Application Summary AI generated
This standard specifies a test method for determining the ultimate aerobic biodegradability of plastic materials by measuring oxygen consumption in a closed respirometer. It is applied in the evaluation of plastics intended for environments such as wastewater treatment plants or natural aqueous systems, where microbial activity breaks down the material. The method is used by researchers and manufacturers to assess the environmental fate of plastics under controlled laboratory conditions.
