In this paper the author has considered a range of products whose average assay percentage varies from 92% to 99% with a minimum specification width of 1% either side or 0.5% one side width for testing the measurement system capability by measuring ‘99% confidence either side expanded measurement uncertainty’ and comparing it with minimum specifications width of the range of products, with a single designed experimentation instead of ‘n’ number of experimental designs (n = number of products in products range).
The author has explained that when & how to take corrective action on measurement system and improve the measurement system capability to the expected level.
The author used the Minitab software, DoE & ANOVA for estimating ‘standard components uncertainties’ and ‘combined uncertainty’ with minimum number of trails and minimum experimental efforts. The methodology had been validated with practical experimentation in which all the Type B uncertainty components are replaced with Type A uncertainty methods, which is more accurate and scientific.
Hence the methodology used in the paper is highly recommended to the laboratories where the ranges of product are measured with same laboratory setup.
