ISO 14853 prescribes an analytical method for determining the ability of plastic materials to be biodegraded in an anaerobic aqueous phase. ISO 14853 measures how much carbon is transiting from the sample to the biogas phases of carbon (CO2 and CH4) during biodegradation under a set of conditions associated with anaerobic digester conditions. The Potential to Validate Status at a Given Point in Time that Helps to Achieve Requirements Connected With The Designation Of The Biodegradability Product. The duration of the test can be from 90 days, according to your product needs.
ISO 14853 Test Method
| Test procedure | In this method, biodegradation is determined in an aqueous system by measuring the rate of production of biogas from anaerobic microorganisms. Sludge activity is tracked using several parallel blank and reference controls. Furthermore, three replicate vessels for each group are also prepared. Changes in the pressure of headspace above the vessels OR flux of biogas, and at the close of the test, inorganic carbon is extracted. |
| Incubation condition | The test substance is added to a sealed container containing digested sludge at a solid concentration between 1 g/L to 3 g/L. This container is then incubated at 35 ± 2ºC for a maximum of 90 days. |
