1.1 The objective of this guide is to provide information to be reviewed and considered by the sensory scientist and consumer researcher who wants to select and use scales to measure responses from consumers or trained assessors. 1.2 This guide 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 a description of the most commonly used scales in the field of sensory evaluation and product testing along with a classification framework for these scales. 1.3 The scope of this guide is limited to the sensory and consumer science professionals selection and use of rating scales when one assessor assigns one symbol/value to one stimulus on an attribute. It does not cover the following: 1.3.1 Details of analysis of data obtained from rating scales, 1.3.2 Guidelines for questionnaire design, 1.3.3 Fundamentals of measurement such as reliability and validity, 1.3.4 Measurement models used to convert scale responses into measures of unobserved sensory or hedonic quantities, 1.3.5 Discrimination testing, 1.3.6 Rankings, and 1.3.7 Multi-item scales. 1.4 Units-The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard. 1.5 This standard 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 determine the applicability of regulatory limitations prior to use.
