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.<\/p>\n

This document is not suitable for the assessment of degradation caused by heat (thermo-degradation) or light exposure (photo-degradation).<\/p>\n
