范围:本文件规定了在固体浓度不超过15%的受控厌氧泥浆消化系统中评估塑料材料最终厌氧生物降解性的方法，该系统通常用于处理污水污泥、牲畜粪便或垃圾。本试验方法旨在确定试验材料中有机碳转化为二氧化碳和沼气的百分比和转化率。 该方法适用于以下材料，前提是其碳含量已知: --天然和/或合成聚合物、共聚物或混合物； --含有增塑剂、着色剂或其他化合物等添加剂的塑料材料； --水溶性聚合物。 它不适用于在试验选择的浓度下对试验微生物有抑制作用的材料。 注:抑制作用可通过抑制试验（e。 g、 ISO 13641-1或ISO 13641-2）。交叉引用:ISO 14853:2016ISO 8245ISO 13641-1ISO 15985ISO 13641-2购买本文件时提供的所有现行修订版均包含在购买本文件中。

Scope: This document specifies a method of evaluating the ultimate anaerobic biodegradability of plastic materials in a controlled anaerobic slurry digestion system with a solids concentration not exceeding 15 %, which is often found for the treatment of sewage sludge, livestock faeces or garbage. The test method is designed to yield a percentage and rate of conversion of the organic carbon in the test materials to carbon dioxide and methane produced as biogas. The method applies to the following materials, provided they have a known carbon content: -- natural and/or synthetic polymers, copolymers or mixtures; -- plastic materials that contain additives such as plasticizers, colorants, or other compounds; -- water-soluble polymers. It does not apply to materials which exhibit inhibitory effects on the test microorganisms at the concentration chosen for the test. NOTE Inhibitory effects can be determined by an inhibition test (e.g. ISO 13641-1 or ISO 13641-2).Cross References:ISO 14853:2016ISO 8245ISO 13641-1ISO 15985ISO 13641-2All current amendments available at time of purchase are included with the purchase of this document.
