BS EN ISO 23977-2:2021 Plastics. Determination of the aerobic biodegradation of plastic materials exposed to seawater - Method by measuring the oxygen demand in closed respirometer
1 Scope
This document specifies a laboratory test method for determining the degree and rate
of the aerobic biodegradation level of plastic materials. Biodegradation of plastic
materials is determined by measuring the oxygen demand in a closed respirometer when
exposed to seawater sampled from coastal areas under laboratory conditions.
The conditions described in this document might not always correspond to the optimum
conditions for the maximum degree of biodegradation, however this test method is designed
to give an indication of the potential biodegradability of plastic materials.
NOTE This document addresses plastic materials but can also be used for other materials.
