ActiveDetermination of the ultimate aerobic biodegradability of plastic materials in an aqueous medium--Method by analysis of evolved carbon dioxide
水性培养液中材料最终需氧生物分解能力的测定 采用测定释放的二氧化碳的方法
Application Summary AI generated
This standard specifies a test method for measuring the ultimate aerobic biodegradability of plastic materials by analyzing the carbon dioxide evolved when the material is exposed to microorganisms in an aqueous medium. It is applied in the environmental testing and certification of plastics, particularly for assessing the biodegradation potential of packaging materials, disposable products, and agricultural films in industrial composting or wastewater treatment environments.
