Plastics. Assessment of the intrinsic biodegradability of materials exposed to marine inocula under mesophilic aerobic laboratory conditions. Test methods and requirements
13.020.40 - Pollution, pollution control and conservation
83.080.01 - Plastics in general
This document specifies test methods and criteria for showing
intrinsic biodegradability in marine environments of virgin plastic
materials and polymers without any preliminary environmental
exposure or pre-treatment.
Test methods applied in this document are carried out at
temperatures in the mesophilic range under aerobic conditions and
are aimed to show ultimate biodegradability, i.e. conversion into
carbon dioxide, water and biomass.
This document neither assesses the constituents, such as
regulated metals or substances hazardous to the environment, nor
potential ecotoxic effects but intrinsic biodegradability only.
These aspects will be considered in a separate standard covering
the overall environmental impact of products intentionally or
accidentally released in the marine environment.
This document does not cover the performance of products made
from biodegradable plastic materials and biodegradable polymers.
Lifetime and biodegradation rates in the sea of products made with
biodegradable plastic materials are generally affected by the
specific environmental conditions and by thickness and shape.
Although results might indicate that the tested plastic
materials and polymers biodegrade under the specified test
conditions at a certain rate, the results of any laboratory
exposure cannot be directly extrapolated to marine environments at
the actual site of use or leakage.
This document is not applicable for “marine biodegradable”
claims of biodegradable plastic materials. For such purpose, see
relevant product standards, if available.
The testing scheme specified in this document does not provide
sufficient information for determining the specific biodegradation
rate (i.e. the rate per available surface area) of the material
under testing. For such purpose, see relevant standards about
specific biodegradation rate, if available.
