This International Standard describes a method for sensory evaluation of test samples with the aim of placing a series of test samples in a ranking order.
The method applies to performing multisample difference testing using the criterion of intensity of single attributes, components of attributes or total impression.
It is especially recommended for the pre-sorting of test samples (to be followed by the application of other test methods) or when other methods are beyond the capabilities of the assessors to use reliably.
Among other things, the method enables the influence of different raw materials, processing, treatment, packaging and storage to be determined.
It may also be suitable for use in the training of assessors.
