This document specifies a laboratory test method to determine the degree and rate of aerobic biodegradation level of plastic materials. Biodegradation is determined by measuring the CO2 evolved by the plastic material when exposed to marine sediments sampled from a sandy tidal zone and kept wet with salt-water under laboratory conditions.
This test method is a simulation under laboratory conditions of the habitat found in sandy tidal zone that, in marine science, is called eulittoral zone.
The conditions described in this International Standard may not always correspond to the optimum conditions for the maximum degree of biodegradation to occur.
Deviations from the test conditions described in this International Standard shall be justified in the test report.
