The Analysis of Sodalime Granule Size Distributions

Abstract

NEDU has developed a procedure for translating mesh sizes given in sodalime specifications to those sieve sizes used in testing laboratories. This procedure is used to establish model Gaussian and log-normal distributions that are capable of meeting the specifications. The mesh size distribution measured by sieving a sodalime sample is then compared to the best model. A chi-square goodness of fit test is used to determine whether or not the sample distribution meets the best model distribution. Several Mathcad documents are provided to explain the mathematical basis for this procedure.
