Plan a discrimination or acceptance test: total servings, servings per panellist, and servings per sample from panel size, samples, and replicates.
Try sample values — fills the form with the worked example below.
–
Total servings
–
Servings per panellist
–
Servings per sample
Equation: Total servings = panellists × samples × replicates; per panellist = samples × replicates; per sample = panellists × replicates.
Method: ISO 6658:2017 general guidance on test design; ISO 4120 / ISO 10399 / ISO 5495 for the test itself.
Assumptions: Every panellist tastes every sample the stated number of times; no drop-outs or missing servings.
Limitations: Planning counts only — it does not randomise serving order (Tool 232) or assign sample codes (Tool 233).
Rounding: All counts are whole numbers.
This is a calculation aid, not a laboratory report — confirm against your accredited method before citing a value.
