適用范圍：This part of ISO 9276 specifies methods for the adjustment of an experimental curve to a reference modelwith respect to a statistical background. Furthermore, the evaluation of the residual deviations, after theadjustment, is also specified. The reference model can also serve as a target size distribution for maintainingproduct quality.This part of ISO 9276 specifies procedures that are applicable to the following reference models:a) normal distribution (Laplace-Gauss): powders obtained by precipitation, condensation or natural products (pollens);b) log-normal distribution (Galton MacAlister): powders obtained by grinding or crushing;c) Gates-Gaudin-Schuhmann distribution (bilogarithmic): analysis of the extreme values of the fine particle distributions;d) Rosin-Rammler distribution: analysis of the extreme values of the coarse particle distributions;e) any other model or combination of models, if a non-linear fit method is used (see bimodal example in Annex C).This part of ISO 9276 can substantially support product quality assurance or process optimization related toparticle size distribution analysis.
