ISO 11056 specifies a method for applying magnitude estimation to the evaluation of sensory attributes. The methodology specified covers the training of assessors and obtaining magnitude estimations as well as their statistical interpretation.
ISO 11056 on methods of sensory analysis through magnitude estimation method is relevant to:
Magnitude estimation is a psychophysical scaling technique where assessors assign numerical values to the estimated magnitude of an attribute. The only constraint placed upon the assessor is that the values assigned should conform to a ratio principle, i.e., if the attribute is twice as strong in sample B in comparison with sample A, the value assigned to sample B has to be twice that assigned to sample A. Attributes such as intensity, pleasantness or acceptability may be assessed using magnitude estimation.
ISO 11056 helps users by specifying a method that allows users to choose their own specific scale for judgments, allowing for in-depth investigations of user perceptions than when categorical scales are used.
Magnitude estimation is the privileged method to determine the Steven’s equation psychophysical power function. It can also be used to solve concrete problems.
