Abstract

Results of interlaboratory testing of the stone aggregate fraction 0 – 4 mm, analysed by variance analysis method (ANOVA), are presented. The experiment was planned with the three-factor staggered- nested model. The repeatability and reproducibility variances, and intermediate precision variances among ranges of results obtained under various reproducibility conditions, were estimated. The estimation of intermadiate variance is significant for determining the influence of heterogeneity of aggregates at each level of testing.
