本文件规定了在实验室规模的需氧条件下，塑料材料制成的样品暴露在海洋环境基质中时物理降解测量的试验方法。 本文件不适用于评估热（热降解）或光照（光降解）引起的降解。

This document specifies test methods for the measurement of the physical degradation of samples made with plastics materials when exposed to marine environmental matrices under aerobic conditions at laboratory scale. This document is not suitable for the assessment of degradation caused by heat (thermo-degradation) or light exposure (photo-degradation).
