DIN EN ISO 14855-2:2009 在控制复合条件下塑料材料极端好气菌生物降解性和非集合性的测定.第2部分:实验室规模试验中释放二氧化碳的比重测量 ISO

This part of ISO 14855 specifies a method for determining the ultimate aerobic biodegradability of plastic materials under controlled composting conditions by gravimetric measurement of the amount of carbon dioxide evolved. The method is designed to yield an optimum rate of biodegradation by adjusting the humidity, aeration and temperature of the compasting vessel. The method applies to the following materials: -- natural and/or synthetic polymers and copolymers, and mixtures of these; -- plastic materials that contain additives such as plasticizers or colorants; -- water-soluble polymers; -- materials that, under the test conditions, do not inhibit the activity of micro-organisms present in the inoculum. If the test material inhibits micro-organisms in the inoculum, another type of mature compost or pre-exposure compost can be used.

DIN EN ISO 14855-1:2008 塑料材料在受控堆肥环境下最终需氧生物降解能力的测定.二氧化碳增量分析法.第1部分:通用方法

This part of ISO 14855 specifies a method for the determination of the ultimate aerobic biodegradability of plastics, based on organic compounds, under controlled composting conditions by measurement of the amount of carbon dioxide evolved and the degree of disintegration of the plastic at the end of the test. This method is designed to simulate typical aerobic composting conditions for the organic fraction of solid mixed municipal waste. The test material is exposed to an inoculum which is derived from compost. The composting takes place in an environment wherein temperature, aeration and humidity are closely monitored and controlled. The test method is designed to yield the percentage conversion of the carbon in the test material to evolved carbon dioxide as well as the rate of conversion. Subclauses 8.6 and 8.7 specify a variant of the method, using a mineral bed (vermiculite) inoculated with thermophilic microorganisms obtained from compost with a specific activation phase, instead of mature compost. This variant is designed to yield the percentage of carbon in the test substance converted to carbon dioxide and the rate of conversion. The conditions described in this part of ISO 14855 may not always correspond to the optimum conditions for the maximum degree of biodegradation to occur.

ISO 16929:2002 塑料.在半工业性实验规模试验规定的合成条件下塑料材料降解程度的测定

This International Standard is 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 compostability of plastics as outlined in ISO 17088, Plastics — Evaluation of compostability — Test scheme for final acceptance (currently under preparation). The test method laid down in this International Standard can also be used to determine the influence of the test material on the composting process and the quality of the compost obtained. It cannot be used to determine the aerobic biodegradability of a test material. Other methods are available for this (see e.g. ISO 14851, ISO 14852 or ISO 14855).
