UpcomingDetermination of the ultimate aerobic biodegradability of plastic materials in an aqueous medium—Part 2: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 第2部分：采用测定释放的二氧化碳的方法
Application Summary AI generated
This standard specifies a laboratory 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 plastics industry for evaluating the environmental fate of biodegradable plastics, particularly in wastewater treatment, composting, or aquatic environments where microbial activity is present. The method is used for product certification, research, and regulatory compliance to determine if a plastic will fully biodegrade under aerobic conditions.
