UpcomingDetermination of the ultimate aerobic biodegradability of plastic materials in an aqueous medium—Part 1: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 第1部分：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 measuring the oxygen demand of plastic materials in a closed respirometer to determine their ultimate aerobic biodegradability in an aqueous medium. It is applied in the environmental testing and certification of plastics, particularly for assessing the biodegradation potential of packaging, disposable products, or other plastic items in industrial wastewater treatment or natural water environments. The method is used by manufacturers and regulatory bodies to verify compliance with biodegradability claims under controlled laboratory conditions.
