标准摘要
[中文适用范围]： 本文件规定了在真实现场条件下测定暴露于海洋生境的塑料材料崩解程度的试验方法。所研究的海洋区域是沙质潮下带和沙质潮间带，塑料材料可能被故意放置（例如可生物降解的渔网），也可能由于人类不负责任的行为而最终成为垃圾。这取决于材料的物理特性、形状和大小，以及水流和潮汐运动。本文件规定了设备的一般要求以及使用所述测试方法的程序。测定暴露于远洋区域（例如海面或海底上方的水柱）的塑料材料的崩解程度不属于本文件的讨论范围。本文件不适用于评估由热或光暴露引起的崩解。所述现场测试是崩解测试，而不是生物降解测试。因此，它不能用于证明生物降解，或做出诸如“在海洋环境中可生物降解”等不合格的声明。 [外文原描述]： This document specifies test methods for the determination of the degree of disintegration of plastic materials exposed to marine habitats under real field conditions. The marine areas under investigation are the sandy sublittoral and the sandy eulittoral zone where plastic materials can either be placed intentionally (e.g. biodegradable fishing nets) or end up as litter due to irresponsible human behaviour. This depends on their physical characteristics, form and size of the materials, and on water currents and tidal movements. This document specifies the general requirements of the apparatus, and the procedures for using the test methods described. The determination of the level of disintegration of plastic materials exposed to pelagic zones such as the sea surface or the water column above the seafloor are not within the scope of this document. This document is not suitable for the assessment of disintegration caused by heat or light exposure. The described field test is a disintegration test and not a biodegradation test. Therefore, it cannot be used for demonstrating biodegradation or for making unqualified claims such as "biodegradable in marine environment" and similar.
