Plastics in marine environments under actual field conditions
Determination of disintegration of plastic materials
1 Scope
This document describes a test method for determining the disintegration of plastic materials exposed to the marine environment under actual field conditions:
The test is preferably conducted in the sandy sub-littoral zone and true coastal zone, where there are often intentionally placed (such as biodegradable fishing nets) or due to
The irresponsible behavior of humans has turned plastic materials into garbage: This depends on the physical properties, shape and size of the plastic, as well as currents and tides
sports:
This document specifies the general requirements for test equipment and describes the test methods:
This document does not apply to the determination of the disintegration properties of plastic materials exposed to the pelagic zone (such as the sea surface or sea water):
This document is not suitable for the evaluation of disintegration due to heat and light:
This document applies to the determination of disintegration properties, not biodegradation properties: Therefore, it cannot be used to prove or disprove biodegradable properties
(such as "biodegradable in the marine environment", etc:):
