This International Standard specifies a method for the determination of the ultimate aerobic biodegradability of
plastics, based on organic compounds, under controlled composting conditions by measurement of the amount of
carbon dioxide evolved and the degree of disintegration of the plastic at the end of the test. This method is designed
to simulate typical aerobic composting conditions for the organic fraction of solid mixed municipal waste. The test
material is exposed to an inoculum which is derived from compost. The composting takes place in an environment
wherein temperature, aeration and humidity are closely monitored and controlled. The test method is designed to
yield the percentage conversion of the carbon in the test material to evolved carbon dioxide as well as the rate of
conversion.
The conditions described in this International Standard may not always correspond to the optimum conditions for
the maximum degree of biodegradation to occur.
