DIN EN ISO 14852-2004 水介质中塑料材料的富氧菌生物降解性的测定.二氧化碳增量分析法
Determination of the ultimate aerobic biodegradability of plastic materials in an aqueous medium - Method by analysis of evolved carbon dioxide (ISO 14852:1999); German version EN ISO 14852:2004
The Standard specifies a method, by measuring the amount of carbon dioxide evolved, for the determination of the degree of aerobic biodegradability of plastic materials, including those containing formulation additives. The test material is exposed in a synthetic medium under laboratory conditions to an inoculum from activated sludge, compost or soil.
