Sustainable measurement/analysis methods

After some sustained work in this area, most notably the Standards, Measurement and Testing (SMT) Programme of the European Commission, the pitfalls that can be encountered when performing speciation analysis are better understood, and methods to evaluate and eliminate them are now reasonably well established.

Abstract This chapter presents a method for aggregation of different indicators, which are relevant for sustainability assessment. The originality of the procedure relies on the use of Averaging Quality Rating method that was used on the level of indicators analysis for making them comparable despite different measurement method (qualitative or quantitative). It is suitable for small- and medium-sized companies (SMEs) where the information system is rather undeveloped. 

A comparison of the experimentally determined critical arch spans /outlet widths and the critical outlet widths calculated from the Jenike method [2] are given in table 2, for fly ash, hydrated lime and olivine sand. In table 2 at filling represents the measured maximum arch span which occurred prior to sustained flow of the stored bulk solid. The intervals on the predicted outlet widths are at the 95% confidence limit determined from statistical analysis of the failure function data. The recommended mass flow design lines [2] correspond with hopper half angles of 37, 28, and 30 degrees respectively for fly ash, hydrated lime and olivine sand.
