1.1 The objective of this document is to provide information to be reviewed and considered by the sensory scientist who wants to select and use scales to measure responses from consumers or trained assessors. 1.2 The document covers a brief definition of scales as well as some fundamental and practical challenges the sensory scientist should be aware of when using scales. It also provides a list and description of the most commonly used scales in sensory measurement along with a classification framework for these scales. 1.3 This guide is limited to aid sensory professionals in the selection and use of rating scales when one assessor assigns one symbol / value to one stimulus on an attribute. It does not cover details of the analysis nor is it intended to provide guidelines for questionnaire design. Fundamentals of measurement are not a focus of this document. Reliability and validity are only briefly covered. Measurement models used to convert scale responses into measures of unobserved sensory or hedonic quantities are not covered, nor are rankings. Lastly, the document focuses on single item scales, and multi-item scales are only briefly discussed. 1.4 This guide does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.
