Sensory analysis. Methodology. Ranking. | Status: Confirmed, Current

1 Scope This International Standard describes a method for sensory evaluation with the aim of placing a series of test samples in rank order. This method allows for assessing differences among several samples based on the intensity of a single attribute, of several attributes1) or of an overall impression. It is used to find if differences exist, but cannot determine the degree of difference that exists between samples. The method is suited for the following cases:

1. a) evaluation of assessors’ performance
   1. 1) training assessors,
   2. 2) determining perception thresholds of individuals or groups;
2. b product assessment
   1. 1) pre-sorting of samples
      1. i) on a descriptive criterion,
      2. ii) on hedonic preference;
   2. 2) determination of the influence on intensity levels of one or more parameters (e.g. order of dilution, influence of raw materials, of production, packaging or storage methods)
      1. i) on a descriptive criterion,
      2. ii) on hedonic preference;
   3. 3) determination of the order of preference in a global hedonic test.
