Abstract / scope
ISO 29842:2011 specifies a method for the application of balanced incomplete block designs to sensory descriptive and hedonic tests.
ISO 29842:2011 applies when the number of test samples exceeds the number of evaluations that an assessor can perform reliably in a single session.
ISO 29842:2011 also specifies the fundamental characteristics of balanced incomplete block designs and establishes guidelines for their application in sensory evaluation.
