英文名称：Plastics — Methods for marine exposure

标准范围

ISO 15314:2004描述了海洋环境中塑料暴露的三种方法。方法A涵盖样品漂浮在表面上的暴露，方法B涵盖样品部分浸没的暴露，方法C涵盖样品完全浸没的暴露。尽管该方法旨在用于海洋（盐水）暴露，但也可用于室外微咸水和淡水暴露。方法A特别适用于可降解性增强的塑料，其中相对于常规塑料材料，在海洋漂浮暴露下的环境降解预计会加速。该标准规定了设备的一般要求，以及使用所述测试方法的程序。它列出了可用于评估海洋暴露后塑料变化的特性。在ISO 4582《塑料——在玻璃、自然风化或实验室光源下暴露于日光后颜色变化和性能变化的测定》中给出了关于测定塑料在暴露时性能变化和报告这些结果的方法的更具体信息。

ISO 15314:2004 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 and method C covers exposures where specimens are completely immersed. Although intended for marine (salt water) exposure, the methodology might be used with outdoor brackish water and fresh-water exposures as well.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.The standard specifies the general requirements for the apparatus, and procedures for using the test methods described.It lists properties that may 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, Plastics -- Determination of changes in colour and variations in properties after exposure to daylight under glass, natural weathering or laboratory light sources.
