ASTM D6400 is the standard specification for solid material biodegradation (by composting) required for the labeling of plastics designed to be aerobically composted in municipal or industrial facilities..
The properties in this specification are those required to determine if plastics and products made from plastics will compost satisfactorily, including biodegrading at a rate comparable to known compostable materials.
Further, the properties in the specification are required to assure that the degradation of these materials will not diminish the value or utility of the compost resulting from the composting process.
