ASTM Manual 26 is the first revision to the classic STP 434/Manual on Sensory Testing Methods (published 1968).

The science of sensory evaluation consists of a broad spectrum of methods and techniques that encompass psychology; statistics; product sciences, such as food science or cosmetic chemistry; other biological sciences; physics and engineering; ergonomics; sociology; and other mathematics, sciences, and humanities.

Some of its most powerful methods require an understanding of how people use language and other communication.

Manual 26 gives the reader a general knowledge of sensory evaluation methods. It provides a base of practical techniques and the controls that are necessary to conduct simple sensory studies.
