<p>This document specifies a laboratory test method to determine the degree and rate of aerobic biodegradation level of plastic materials. This test method can also be applied to other materials.</p>
<p>Biodegradation is determined by measuring the CO<sub>2</sub> 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.</p>
<p>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.</p>
<p>The conditions described in this document might not always correspond to the optimum conditions for the maximum degree of biodegradation to occur.</p>
<p>Deviations from the test conditions described in this document are justified in the test report.</p>
