标准范围

本文件描述了在海洋环境中暴露塑料的三种方法。方法A包括试样漂浮在表面上的暴露，方法B包括试样部分浸入的暴露，方法C包括试样完全浸入的暴露。尽管该方法适用于海洋（咸水）暴露，但也可用于室外微咸水和淡水暴露。ISO 877-1、ISO 877-2和ISO 877-3中描述了塑料在陆地上的直接风化。方法A特别适用于增强降解性塑料，其中，与常规塑料材料相比，海上漂浮暴露下的环境降解预计会加快。本文件规定了仪器的一般要求，以及使用所述试验方法的程序。它列出了可用于评估暴露在海洋中的塑料变化的特性。ISO 4582中给出了有关测定塑料暴露后性能变化和报告这些结果的方法的更具体信息。

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.
