1. Scope
This Standard Guide covers acceptance and preference measures when each is used in an unbranded two-sample test. This Guide covers how to establish a products hedonic or choice status based on sensory attributes alone, rather than brand, positioning, imagery, packaging, emotional, socio-cultural responses, or other non-sensory aspects of the products. The most commonly used measures of acceptance and preference will be covered, i.e., product liking overall as measured by the 9-point hedonic scale, a line scale, the labeled affective magnitude scale, and pictures scales, and choice measured by overall preference, either forced choice or with the no preference option.
Any organization that needs to know if a product is liked or preferred by end-users. No standard guide that covers issues to consider in hedonic product testing currently exists.
