DIN EN 17417-2021 塑料在缺氧(反硝化)条件水性培养液中最终生物分解能力的测定. 采用测量增压的方法
Determination of the ultimate biodegradation of plastics materials in an aqueous system under anoxic (denitrifying) conditions - Method by measurement of pressure increase; German version EN 17417:2020
This document specifies a method for the determination of the ultimate anoxic biodegradability of plastics made of organic compounds, where the amount of the produced nitrogen and carbon dioxide at the end of the test is measured. The test substance is exposed to an inoculum stem
