标准范围
This document describes three methods for the exposure of plastics in a marine environment. Method A
covers exposures where specimens float on the surface, method B covers exposures where specimens
are partially immersed method C covers exposures where specimens are completely immersed.
Although intended for marine (salt water) exposure, the methodology can be used with outdoor
brackish water and fresh-water exposures as well. Direct weathering of plastics on land is described in
ISO 877-1, ISO 877-2 and ISO 877-3.
Method A is particularly applicable to enhanced-degradability plastics where the environmental
degradation under marine floating exposure is expected to be accelerated relative to that of regular
plastic materials.
This document specifies the general requirements for the apparatus, and procedures for using the test
methods described.
It lists properties that can be used to evaluate changes in plastics subjected to marine exposure. More
specific information about methods for determining the changes in properties of plastics on exposure
and reporting these results is given in ISO 4582.
