本文件定义了一种试验方法，用于确定在规定条件下进行的中试规模好氧堆肥试验中塑料材料的分解程度。它是ISO 17088中概述的塑料工业可堆肥性评估总体方案的一部分。 本文件中规定的试验方法也用于确定试验材料对堆肥过程和获得的堆肥质量的影响。本试验方法不能用于确定试验材料的好氧生物降解性。 注:本试验可采用其他方法（例如，参见ISO 14851、ISO 14852或ISO 14855-1和ISO 14855-2）。

This document defines a test method used to determine the degree of disintegration of plastic materials in a pilot-scale aerobic composting test under defined conditions. It forms part of an overall scheme for the evaluation of the industrial compostability of plastics as outlined in ISO 17088. The test method laid down in this document is also used to determine the influence of the test material on the composting process and the quality of the compost obtained. This test method cannot be used to determine the aerobic biodegradability of a test material. NOTE Other methods are available for this test (for example, see ISO 14851, ISO 14852 or ISO 14855-1 and ISO 14855-2).
