Popis
BS EN 17417:2020
This standard BS EN 17417:2020 Determination of the ultimate biodegradation of plastics materials in an aqueous system under anoxic (denitrifying) conditions. Method by measurement of pressure increase is classified in these ICS categories:
- 13.030.99 Other standards related to wastes
- 83.080.01 Plastics in general
This document specifies a method for the determination of the ultimate anoxic biodegradation 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 stemming from the denitrification tank of a wastewater treatment plant. Testing is performed under defined laboratory conditions.
Claims of performance are limited to the numerical result obtained in the test and not used for making unqualified claims such as “disposable in waste water treatment plants” and similar.
