The part of JIS Z 8402 -- 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 of JIS Z 8402 complements JIS Z 8402-2 by providing alternative designs that may be of more value in some situations than the basic design given in JIS Z 8402-2, and by providing a robust method of analysis that gives estimates of the repeatability and reproducibility standalrd deviations that are less dependent on the data analyst's judgement than those given by the methods described in JIS Z 8402-2.
