本文件描述了一种通过测量吸氧率（OUR）来确定生长基质和土壤改良剂或其成分的有氧生物活性的方法。吸氧率是可生物降解有机物在特定时间段内被分解程度的指标。该方法不适用于粒度>10 mm且含量超过20%的材料。交叉引用:EN 13039EN 45501EN ISO 3696EN 13040购买本文件时可获得的所有现行修订均包含在购买本文件中。

This document describes a method to determine the aerobic biological activity of growing media and soil improvers or constituents thereof by measuring the oxygen uptake rate (OUR). The oxygen uptake rate is an indicator of the extent to which biodegradable organic matter is being broken down within a specified time period. The method is not suitable for material with a content of particle sizes > 10 mm exceeding 20 %.Cross References:EN 13039EN 45501EN ISO 3696EN 13040All current amendments available at time of purchase are included with the purchase of this document.
