Scope

1.1 This guide covers reasonable practices for designing and implementing sensory tests that validate claims pertaining only to the sensory or perceptual attributes, or both, of a product. This guide was developed for use in the United States and must be adapted to the laws and regulations for advertisement claim substantiation for any other country. A claim is a statement about a product that highlights its advantages, sensory or perceptual attributes, or product changes or differences compared to other products in order to enhance its marketability. Attribute, performance, and hedonic claims, both comparative and non-comparative, are covered. This guide includes broad principles covering selecting and recruiting representative consumer samples, selecting and preparing products, constructing product rating forms, test execution, and statistical handling of data. The objective of this guide is to disseminate good sensory and consumer testing practices. Validation of claims should be made more defendable if the essence of this guide is followed.
