DIN ISO 9276-4-2006 粒度分析结果的表示.第4部分:分类过程的特性(ISO 9276-4-2001)
Representation of results of particle size analysis - Part 4: Characterization of a classification process (ISO 9276-4:2001);English version of DIN ISO 9276-4:2006-02
The main object of this part of ISO 9276 is to provide the mathematical background for the characterization of a
classification process. This part of ISO 9276 is not limited to an application in particle size analysis, the same
procedure may be used for the characterization of a technical classification process (e.g. air classification,
centrifugal classification) or a separation process (e.g. gas or hydrocyclones).
In clause 3 the characterization of a classification process is described under the presupposition that the density
distribution curves describing the feed material and the fractions, as well as the overall mass balance, are free from
errors. In clause 4 the influence of systematic errors on the efficiency of a classification process is described. The
effect of stochastic errors in the characterization of a classification process is described in annex A.
