Gives detailed descriptions of alternatives to the basic procedure for determination of the repeatability and reproducibility standard deviations of a standard measurement procedure, i.e. the split-level design and a design for heterogeneous materials, and covers the use of robust procedures for analyzing the results of precision experiments without the use of outlier tests to exclude data from the calculations, especially the detailed use of one such procedure.

This part ofISO5725

  • provides detailed descriptions of alternatives to the basic method for determining the repeatability and reproducibility standard deviations of a standard measurement method, namely the split-level design and a design for heterogeneous materials;

  • describes the use of robust methods for analysing the results of precision experiments without using outlier tests to exclude data from the calculations, and in particular, the detailed use of one such method.

This part ofISO5725 complements ISO5725‑2 by providing alternative designs that may be of more value in some situations than the basic design given in ISO5725‑2, and by providing a robust method of analysis that gives estimates of the repeatability and reproducibility standard deviations that are less dependent on the data analyst\'s judgement than those given by the methods described in ISO5725‑2.
