Scope
GB/T 19276.2-2026 is the English-translated version of 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.
Plastics that are intended to break down in water need a way to show how far they are converted by microorganisms. This standard, Part 2 of the series on aerobic biodegradability in an aqueous medium, specifies a method that analyses the carbon dioxide evolved to determine the ultimate aerobic biodegradability of plastic materials. It is a recommended national standard.
Producers of biodegradable plastics, packaging companies, environmental and materials laboratories, certification bodies and researchers working on degradable polymers can use it. Customers who request biodegradation data for a product may also refer to it as the method behind the claim.
It was issued on 31 March 2026 and takes effect on 1 October 2026. It replaces GB/T 19276.2-2003, so laboratories that use the earlier edition should review their methods and equipment.
