Plastics. Determination of the ultimate anaerobic biodegradation of plastic materials in an aqueous system. Method by measurement of biogas productionBS ISO 14853: 2005 Plastics. Determination of the ultimate anaerobic biodegradation of plastic materials in an aqueous system. Method by measurement of biogas production BS ISO 14853 specifies a method for the determination of the ultimate anaerobic biodegradability of plastics by anaerobic microorganisms. The conditions described in BS ISO 14853 do not necessarily correspond to the optimum conditions for the maximum degree of biodegradation to occur.
