Revision of E1885-18 Standard Test Method for Sensory Analysis—Triangle Test


The standard in the Triangle Test Method will be updated, along with all of the other standards on forced choice discrimination test methods, to make the Thurstonian delta the primary measure of the magnitude of a sensory difference, with the proportion discriminators, P(d), from the guessing model becoming a secondary metric. Other technical and editorial changes will be made as needed.
