In the run-up for amending the Austrian landfill ordinance, parameters were developed to assess the stability/reactivity of mechanically-biologically pretreated residual wastes. The Landfill Ordinance 2008 regulates limit values for Respiration Activity (="Atmungsaktivität") RA(4) (AT(4))<7mgO(2)(g dry matter (DM))(-1), Gas Generation Sum GS(21)<20NlkgDM(-1) and alternatively Gas Evolution (="Gasbildung") GB(21)<20Nl*kgDM(-1). Methods for analysing these parameters were established by the Austrian Standards Institute (2004). As laboratory practice shows, these methods also are used for the assessment of other wastes (sewage sludge, commercial waste, material from abandoned sites, biowaste compost). For measurement of respiration activity in Austria mainly two methods are used: the Sapromat®-method and the OxiTop®-method. Whether respectively to what extent these two methods give same results, is discussed in this paper. Since 2009 at ABF-BOKU 169 respiration activity tests of samples taken from different stages of MBT - as well as biowaste composting processes, materials from landfills as well as abandoned sites and residues from anaerobic treatment plants were analysed parallel by Sapromat® and OxiTop®. The results manifest very strong correlation between the Sapromat® and OxiTop® method. The correlation coefficient is 0.993. As a very clear tendency OxiTop® gives lower amounts than Sapromat®. In average the lower values of OxiTop® are around 88%.
在修订奥地利垃圾填埋条例之前，制定了一些参数来评估机械-生物预处理残余废物的稳定性/反应性。2008 年的《垃圾填埋条例》规定了呼吸活性 (="Atmungsaktivität") RA(4)（AT(4)）<7mgO(2)(g 干物质 (DM))(-1)、气体产生总和 GS(21)<20NlkgDM(-1)和气体生成 ("Gasbildung") GB(21)<20Nl*kgDM(-1)的限值。奥地利标准协会 (2004 年) 制定了分析这些参数的方法。实验室实践表明，这些方法也可用于评估其他废物（污水污泥、商业废物、废弃场地材料、生物废物堆肥）。在奥地利，主要使用两种方法来测量呼吸活性：Sapromat®法和 OxiTop®法。本文讨论了这两种方法是否能给出相同的结果。自 2009 年以来，ABF-BOKU 169 项取自不同阶段的 MBT 以及生物废物堆肥过程、垃圾填埋场和废弃场地的材料以及厌氧处理厂的残留物的样本的呼吸活性测试，通过 Sapromat®和 OxiTop®平行进行分析。结果表明 Sapromat®和 OxiTop®方法之间具有很强的相关性。相关系数为 0.993。OxiTop®给出的数值明显较低，呈非常清晰的趋势。平均而言，OxiTop®的低值约为 88%。
