DIN EN ISO 11136:2017-10

ISO 11136:2014 covers a general guidance for conducting hedonic tests with consumers in a controlled area. It uses tests based on collecting consumers' responses to questions, generally on paper or via a keyboard or a touch screen. Tests of a behavioural nature (such as recording quantities consumed ad libitum by the consumers) do not fall within the scope of ISO 11136:2014. The document covers also requirements for the recruitment of consumers, for the assembling a consumer sample, for the specification of the design of the controlled area, presentation of samples and a number of informative Annexes containing examples for data Analysis and an example of a recruitment questionnaire.
