The abilities of 70 individuals to serve as judges in laboratory‐type sensory panels were investigated. The ability to detect differences between the degrees of corrosion of cans and a low variability in judgments served as criteria for acceptance or rejection of an individual as sensory judge. An unstructured rating scale method was used for the sensory analysis. Data were evaluated by means of Spearman's rank correlation coefficient as well as by Wald's sequential analysis. Spearman's rank correlation coefficient proved to be of only limited value in this instance because it did not yield the desired effect of separation whereas Wald's sequential analysis allowed to influence the number of accepted judges by properly specifying calculation parameters.
