Describes a method for the evaluation of the ultimate aerobic biodegradability of packaging materials based on organic compounds under controlled composting conditions by measurement of released carbon dioxide at the end of the test.

This European Standard specifies a method for the evaluation of the ultimate aerobic biodegradability of packaging materials based on organic compounds under controlled composting conditions by measurement of released carbon dioxide at the end of the test. This method is designed to resemble typical aerobic composting conditions for the organic fraction of mixed municipal solid waste. The packaging material is exposed in a laboratory test to an inoculum which is derived from compost. The aerobic composting takes place in an environment where especially temperature, aeration and humidity are closely monitored and controlled. The test method is designed to yield a percentage and rate of conversion of carbon of the test material to released carbon dioxide.

The conditions described in this European Standard do not necessarily always correspond to the optimal conditions allowing the maximum degree of biodegradation to occur.
