適用范圍：This International Standard 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 wherespecimens are partially immersed and method C covers exposures where specimens are completelyimmersed. Although intended for marine (salt water) exposure, the methodology might be used with outdoorbrackish water and fresh-water exposures as well. Direct weathering of plastics on land is described in ISO 877.Method A is particularly applicable to enhanced-degradability plastics where the environmental degradationunder marine floating exposure is expected to be accelerated relative to that of regular plastic materials.This International Standard specifies the general requirements for the apparatus, and procedures for using thetest methods described.It lists properties that may be used to evaluate changes in plastics subjected to marine exposure. More specificinformation about methods for determining the changes in properties of plastics on exposure and reportingthese results is given in ISO 4582.
