Overview
ISO 5492:2008/Amd 1:2016 is an amendment to ISO 5492:2008 - the international vocabulary for sensory analysis. Rather than prescribing procedures, this amendment expands and clarifies terminology used across sensory science. It was prepared by ISO/TC 34 (Food products), Subcommittee SC 12 (Sensory analysis) and adds definitions under general terminology, senses, and methods to support consistent communication in sensory testing and research.
Key topics
The amendment introduces clear, standardized definitions for terms widely used in sensory analysis, including:
- General terminology
- assessor bias, order bias, position bias, sequential bias, outlier
- homogeneity, repeatability, reproducibility
- Terminology relating to the senses
- retronasal, after-smell (residual smell), tactile after-feel
- Terminology relating to methods
- blind test, branded test, central location test, home-use test
- complete block design, incomplete block design, repetition, session
- closed-ended and open-ended questions, forced-choice method, in-out test
- conjoint analysis, flash profiling, consensus sensory profile, controlled area
These additions improve clarity about assessor effects (bias types), agreement measures (repeatability/reproducibility), sensory pathways (retronasal), and experimental designs/methods.
Applications
This vocabulary amendment is practical for anyone involved in sensory testing and product evaluation. Typical uses include:
- Harmonizing terminology in sensory protocols, reports and publications
- Designing experiments (choosing complete vs incomplete block designs)
- Training and calibrating panels to recognize and mitigate assessor bias
- Specifying test conditions (controlled area, central location vs home-use)
- Interpreting results consistently across labs (repeatability, reproducibility)
- Applying modern profiling methods (flash profiling, conjoint analysis)
Who benefits:
- Sensory scientists and panel leaders
- R&D and product development teams (food, beverage, consumer goods)
- Quality assurance and regulatory professionals
- Market researchers and consumer insights teams
- Academic researchers teaching sensory methodology
